					PART I


ITEM 1 - BUSINESS

General

Sutron Corporation (the Company) was incorporated on 
December 30, 1975 under the General Laws of the Commonwealth
of Virginia.  The Company designs, manufactures and markets
products and provides services that enable government and commercial
entities to monitor and collect hydrological and meteorological
data for the management of critical water resources, for early 
warning of potentially disasterous floods or storms and 
for the optimization of hydropower plants.

The Company's headquarters is located at 21300 
Ridgetop Circle, Sterling, Virginia 20166, and the Company's 
telephone number at that location is (703) 406-2800. The Company 
maintains a worldwide web address at www.sutron.com. The Company
makes available free of charge through the Investors section 
of the Company's website at www.sutron.com the annual, quarterly
and current reports, and amendments thereto, which the Company
files with, or furnishes to, the SEC. Such reports and 
amendments are available on the Company's website as soon as 
reasonably practical after the Company has filed such reports 
with, or furnished such reports to, the SEC. 

Sutron is focused on providing real-time solutions and 
services to our customers in three areas of the hydrological
and meteorological markets.  First, we provide dataloggers, 
satellite transmitters/loggers and sensors. Second,
we provide turnkey integrated systems for hydrological and
meteorological monitoring networks and airport weather systems. 
Third, we provide services consisting of installation, 
maintenance of hydrological and meteorological systems, and 
other related engineering services.  The Companys customers
include a diversified base of federal, state, local and foreign
governments, engineering companies, universities, and hydropower
companies.

The Company's ongoing, strategic business units consist of the
Company's Hydromet Products Divison, the Integrated Systems
Division, the Hydrological Services Division and the Airport
Weather Systems division. Each unit includes a range of products
and services designed to meet the specific needs of a particular
customer segment. 


Hydromet Products Division

The Hydromet Products Division manufactures dataloggers,
satellite transmitters/loggers and sensors. Sutron's data loggers
collect sensor data and transmit the data to central facilities 
primarily by satellite radio but also by telephone, fiber optics
and microwave. Sutron's sensors support the collection 
of hydrological and meteorological data and include a tipping 
bucket rain gauge, a barometric pressure sensor, a temperature 
sensor, and several water level sensors. The Companys 
equipment is compatible with sensors from other companies.  
Sutron has long-standing relationships with suppliers for wind 
speed and wind direction, water quality, humidity and solar 
radiation sensors.  The Company received an ISO 9001 
certification on March 12, 1999 and an ISO 9001:2000 certification
on August 13, 2003.  The principal products that are manufactured
by the Hydromet Products Division are described below.

                                     2 
 
  ------------------------------------------------------------------------ 


8210 Data Logger

The 8210 Data Logger/Transmitter is a simple-to-
operate, low-cost data collection platform which supports a 
wide variety of telemetry applications.  The 8210 is 
environmentally hardened, capable of operating from -40 C to 60 
C, making it ideal for remote locations. As a data recorder, 
the 8210 will store over 65,000 readings in battery backed 
memory.  The 8210 supports a wide variety of communications,
including radio, satellite, and telephone.  The 
Telephone/Voice Synthesis option allows communications over 
standard telephone circuits using either a synthesized voice 
message or a modem connected to a computer terminal.

Xpert and XLite Dataloggers

The Xpert Datalogger is the Companys next generation datalogger.
It has a  Microsoft CE operating system, a 486 processor, C++ 
programming and standard 2 MB memory that is expandable to over 
1 gigabyte.   The Xpert has enabled the Company to enter closely
related environmental markets such as tides and weather monitoring.  The 
XLite, a derived product based on the Xpert, does not have a display but
is similarly capable.  The XLite was  released at the end of 2001. 

SatLink2

In January 2004, the SatLink2 was certified by the National
Environmental Satellite, Data and Information Service (NESDIS).
The SatLink2 is a redesign of the original SatLink transmitter
in order to improve margins and to provide the latest features.
The SatLink2 is a high data rate satellite transmitter that 
transmits at 100, 300 and 1200 baud, incorporates GPS and functions
as a logger. The original SatLink was certified by NESDIS in 
July 2001 for operation on the Geostationary Operational Environment
Satellite (GOES)system. NESDIS operates two U.S.Government 
environmental satellites on this system.  All GOES customers 
are mandated by NESDIS to purchase high data rate satellite 
transmitters and to replace all old 100 baud transmitters 
within a ten-year period beginning in July 2001.  NESDIS made this a
requirement in order to increase the amount of data that the two 
GOES satellites can handle. SatLink is also certified on satellite 
systems in Europe and Asia and relays data from even the most
remote sensors and loggers to everywhere around the globe and 
works with virtually all dataloggers. SatLink is programmable from 
any PC using software provided with the unit. 

Accubar Gauge Pressure Sensor

The Accubar Gauge Pressure sensor is a highly accurate solid state
pressure transducer capable of measuring air/dry gas pressures
from 0 to 22 psi with a maximum pressure of 35 psi.  It is housed
in an aluminum case and with its low power consumption and low
maintenance requirements, it is ideal for remote monitoring
applications.

AccuBubble Self-Contained Bubbler System

The AccuBubble Self-Contained Bubbler is a mercury-free and 
nitrogen-free bubbler apparatus designed for low maintenance 
water level measuring. Using the Sutron Accubar Pressure Sensor
as the control and sensing element makes the AccuBubble a very 
stable and highly accurate water level measuring device.
The AccuBubble uses power conservation techniques to minimize 
current consumption. The bubbler purges the orifice line prior to 
each measurement. This eliminates the need for a constant bubble rate, 
which has been known to consume excessive power. In addition, the 
purging sequence prevents debris build up in the orifice line.
The AccuBubble uses an oil-less, non-lubricated piston and cylinder
compressor. This type of compressor is designed to give consistent 
air delivery without the use of a diaphragm which can rupture over time.
The AccuBubble uses the SDI-12 communications protocol as the control
interface. This allows the unit to be configured by any data loggers 
supporting the SDI-12 standard.

Tides and Ports Systems

The National Ocean Survey (NOS), part of the National Oceanic and 
Atmospheric Administration (NOAA), has the responsibility to accurately
measure tide levels around the perimeter of the United States. NOS ensures
that measurements have the highest accuracy by using the best water
level instruments available. In 2004 and 2003 our Hydromet Products Division 
provided state-of-the-art tide stations to the National Ocean Survey
valued at $900,000 and $676,000.  Tide stations are based on our Xpert
data logger and SatLink2. Xperts run the powerful Windows CE multi-tasking
operating system and the Company has taken advantage of Windows CE to equip
each tide station with software that meets and exceeds all of the NOS 
requirements.   In 2004, the Company enhanced the capabilities of tides
systems by adding Storm Surge/Tsunami software.  This software provides
added capability to provide tsunami warnings.

                                     3
 
  ------------------------------------------------------------------------ 


Integrated Systems Division 

The Integrated Systems Division provides system integration services
consisting of the design and development of customer-specific hardware 
configurations and software applications for hydrological and 
meteorological monitoring and control systems, the sale of Sutrons
real-time database software (XConnect), and long-term software 
support for XConnect users.  This capability allows the Company
to provide turnkey hydrological and meteorological systems to 
a variety of users.  Projects range in size from one station to hundreds
of stations.  Projects usually require design, equipment integration,
software application development and installation and training on both
hardware and software.  Projects can range in duration from a few days
to twelve months depending on the scope and complexity of the system.

Hydrological Services Division

The Company provides hydrological services including equipment
installation and maintenance, data interpretation and analysis,
flow modeling (low flow, rainfall runoff, unsteady flow routing,
water surface profiles), field studies (time of travel, diffusion,
dispersion, calibration of flow control structures, site location),
hydrologic studies (water budget, regression analysis, basin 
inventory studies) and environmental permitting.

Airport Weather Systems

The Airport Weather Systems Division was started in July 2003 
with the hiring of a division manager with over 20 years experience
in the Automatic Weather Observation System (AWOS) market.  AWOS
stations are installed at airports and provide monitoring of 
real-time weather data that is crucial to flight safety. An AWOS 
station typically includes a sensor suite to measure wind direction
and speed, temperature, relative humidity, precipitation, and barometric
pressure as well as cloud height and horizontal visibility/RVR.  Sensors
are connected to a Sutron datalogger which processes the data, stores it
in a relational database and transmits real-time weather parameters to all
designated users, regardless of location.  The system produces weather 
reports for aviation and meteorological use, virtually automatically and 
without need of human intervention. Sutron is leveraging its 
experience with sensors and data collection to enter this market.

Distribution Methods of Products and Services

The Companys products and services are currently sold in the 
United States by the Companys direct sales force.  As of 
December 31, 2004, the Company employed seven salaried sales and 
marketing personnel, including four engaged directly in field 
sales activities, and three in various other marketing and sales 
support functions.  Internationally, the Company utilizes 
agents to sell its products and services.

                                     4
 
  ------------------------------------------------------------------------ 


Customers

During 2004, approximately 44% of the Companys products and 
services were sold to the Federal Government.  Revenues in 2004 
among the various agencies were as follows: Department of
Defense, 16%; Department of the Interior, 20%; Department of
Commerce, 6% and various other agencies of the federal 
government, 2%.  The revenues from the Corps of Engineers 
were spread among some ten (10)  separate Districts, and the
revenues from the Department of the Interior among two (2) 
agencies, the U.S. Geological Survey and the Bureau of Reclamation. 

The Company also performed on various contracts of foreign 
origin.  Total revenues from foreign customers amounted to 
approximately 32% of total revenues in 2004, 28% of total 
revenues in 2003 and 29% in 2002. Sutron actively markets
its products and services internationally.

Contracts for products or services with federal, state and 
local government agencies typically allow for termination at 
the convenience of the government and for audit and annual 
negotiation of overhead rates.  Upon termination, the Company 
would be entitled to reimbursement for allowable costs incurred 
and to a proportionate share of profits or fees earned to the 
date of termination.  Such contracts are also typically 
dependent upon compliance by the contractor with applicable 
civil rights, equal employment opportunity, and contract 
procurement requirements.  

The Company at this time has no reason to believe that any 
material changes will occur in the 
foreseeable future with respect to federal, state, or local 
government programs or services with respect to which the 
Company has been granted its contracts or provides its 
services.  However, due to changes in administration, national 
goals and budgetary restrictions, funding of such programs or 
services could be altered or abolished.  If a substantial cut-
back in the level of funding by the applicable government 
agency were to occur, it would have a material adverse effect 
on the Company.  

Competition

The Company is aware of both domestic and foreign competitors 
offering complete real-time networks of their own and 
companies which fabricate real-time networks from components 
manufactured by themselves and others. The Company is also 
aware of numerous additional firms, ranging in size from large 
to small, from general to highly specialized, and from new to 
well established, offering competitive dataloggers, high data 
rate satellite transmitters, sensors and other instruments 
and software.

Several of these companies have financial, research and 
development, marketing, management and technical resources 
substantially greater than those of the Company.  The Company 
may also be at a competitive disadvantage because it purchases 
certain sensors and other equipment components, as well as 
computer hardware and peripheral equipment, from manufacturers 
who are or may become competitors with respect to one or more 
of the Companys products.

The Company, with respect to its professional engineering and 
technical services, is in competition with numerous diverse 
engineering and consulting firms, many of which have larger 
staffs and facilities, and are better known, have greater 
financial resources, and have more experience than the Company. 
As to its hydrological services, the Company is aware that many 
firms offer equipment installation and maintenance services; 
some of these companies have larger staffs, are better equipped,
and have greater financial, marketing and management resources 
than the Company.

Price, performance and experience are believed by 
the Company to be the primary competitive factors with respect 
to all of its products and services.

                                     5
 
  ------------------------------------------------------------------------ 


Research and Development

During the three years ended December 31, 2004, 2003, and 2002,
Sutron's internally funded research and development costs were
$1,018,874, $1,065,558 and $1,480,706 respectively. 

In 2004, the Companys product development focus was on continual 
improvement of the SatLink2 and other core products.  The Company
certified the SatLink2 to operate on the European/African 
geostationary satellite system, METEOSAT, and on the Chinese 
environmental satellite, FY-2C.  The Company expects China to be a 
significant market.  The Company also worked towards certification
of a 40 Watt SatLink2 that can be installed on existing
and new ocean system buoys to send ocean and weather parameters
including tsunami warnings through the global geostationary
satellite systems in near real time. Certification of the 40 Watt
SatLink2 was received from NESDIS in March 2005.

The Company invested heavily in the redesign of the SatLink transmitter
beginning in 2002 and continuing in 2003.  In January 2004, the 
SL2-G312-1 Satellite Transmitter (SatLink2) was certified by the 
NESDIS. The SatLink2 is a redesign of the original SatLink transmitter 
in orderto improve our margins and to provide the latest features.  It
is not only a satellite transmitter but also has logging capability which 
is attractive to customers who have limited logging requirements and 
therefore avoids the purchase of a separate datalogger.

In 2002, the company released the logger version of the SatLink
and developed tidal monitoring applications based on the Xpert and 
XLite products that were instrumental in winning orders from the 
National Ocean Survey for tides systems.  The Company released 
the Xpert and XLite dataloggers in 2001. 

In 2002, the Company also released XConnect, a base station 
software application that is compatible with leading database 
software including Oracle and Microsoft SQL Server.  The Company 
added enhancements to XConnect's reporting features in 2003 
incorporating Crystal reports.

Patents, Trademarks, Copyrights and Agreements

Although the Company does not deem patent protection to be of 
significant importance to its industry, it has and may in the 
future seek patents for certain of its products, real-time 
networks, and technology as well as Company software products, 
real-time networks, and technology.  Company software products 
and innovations may not be patentable but may be subject to 
automatic but limited copyright protection.  The Company has
 treated its products, real-time networks, technology and 
software as proprietary and relies on trade secret laws and 
internal non-disclosure safeguards rather than making their 
designs and processes generally available to the public by 
applying for patents.  Further, the Company believes that, 
because of the rapid pace of technological change in the 
computer, electronics and telecommunications industries, patent 
and copyright protection is of less significance than factors 
such as the knowledge and experience of Company personnel and 
their ability to design and develop enhanced and new products, 
real-time networks and their components.

Raw Materials

The raw materials used by the Company, such as electronic 
components and fabricated parts, are generally available from a 
wide variety of sources at competitive prices. The Company does 
not anticipate that its present or proposed business activities 
would be substantially adversely affected by the scarcity of 
any raw materials.  

Backlog

The Companys backlog at December 31, 2004 was $5,620,968 as
compared with $4,350,688 at December 31, 2003.  The Company 
anticipates that 76% of its 2004 year-end backlog will be 
shipped in 2005.

Employees

The Company had a total of 72 employees as of December 31, 
2004 of which 71 were full time.

                                     6
 
  ------------------------------------------------------------------------ 


ITEM 2 - PROPERTIES

On July 30, 1992, the Company entered into a five and one-half 
year lease, for approximately 17,000 square feet of 
manufacturing and office space in Sterling, Virginia.  The 
lease commenced on October 23, 1992.  This facility allowed the 
Company to consolidate it's manufacturing, systems integration, 
research and development, and sales and administration 
departments into one building.  An option for an additional five 
years was exercised in 1997.  An option for an additional 
three years was exercised in November 2002.  The lease will 
expire in March 2006.

In July, 1999, the Company leased additional space of approximately
7,000 square feet in Sterling, Virginia.  Two departments, integrated 
systems and research and development were relocated to the new space 
during fiscal year 2000 in order to provide increased production and
warehouse space at the corporate headquarters. The lease expires in
March 2003 and has been renewed for three more years and will expire
in March 2006.

The Company entered into a lease agreement in October 2002 for 
approximately 3800 square feet of office and warehouse space in West 
Palm Beach, Florida. The four year lease expires in October 2006. The
Hydrological Services division will use this space which consists of
both office and warehouse space. 

The Company entered into a  lease agreement for approximately 1500
square feet of office space in Brandon, Florida.  The five-year lease,
expires in December 2008.  The Hydrological Services division will 
use this space for offices.

The Company entered into a lease agreement for approximately 1800
square fet of office space in New Delhi, India in November 2004.
The lease term is month to month.  The India branch office will
use this space for offices.

The Company believes that its facilities are adequate for its 
present needs and that its properties are in good condition, 
well maintained and adequately insured.

ITEM 3 - LEGAL PROCEEDINGS

From time to time, the Company is involved in litigation with 
customers, vendors, suppliers and others in the ordinary course 
of business, and a number of such claims may exist at any given time. 
All such existing proceedings are not expected to have a material 
adverse impact on the Company's results of operations or financial
condition. The Company is a party to the proceedings discussed below. 

In 2003, the Company filed a claim with the Advance Tax Court 
of India seeking a ruling on a decision by the Government of 
Andhra Pradesh (GoAP) of India to assess a 48% income tax on the 
Company's contract of approximately $1,606,000.  The GoAP believed
that the Company had established a branch office in India and was 
therefore subject to Indian income tax.  Although the Company did
file an application for branch office status and received approval
to open a branch office, the Company did not complete the 
registration and approval process with the Government of India
and had not opened a branch office in India.  The income tax 
amount that is at issue was approximatly $770,000.  

The Advance Tax Court of India heard the case in September 2004 and
ruled that Sutron Corporation has a Permanent Establishment in 
India by virtue of its Country Manager who maintains an office
in New Delhi.  The Country Manager has the authority to sign
contracts and perform other duties on behalf of the Company that
fulfills the requirements of Indian tax law and as defined in
Double Taxation Avoidance Agreement with the United States of
America.  

As a result of this ruling, Sutron Corporation entered into
an agreement with Ernst & Young, New Delhi, India to file tax
returns  for the tax periods April 1, 2002 to March 31, 2003
and April 1, 2003 to March 31, 2004.  The returns for both 
tax periods were filed in October 2004.  A refund in the 
amount of approximately $137,000 will be issued to Sutron for the
tax period ending March 31, 2003 resulting from excess withholdings
by the Government of Andhra Pradesh in excess of the tax amount of
approximately $5,250.  A tax payment of approximately
$5,600 was made for the tax period ending March 31, 2004.  All taxes
paid in India will be applied as income tax credits on the
Company's U.S. tax returns in accordance with the Double 
Taxation Avoidance Agreement with the United States of America
and will therefore offset federal taxes.  
           
	                          7
 
  ------------------------------------------------------------------------ 


The Company is currently awaiting acceptance on two systems that
were provided to the Government of Andhra Pradesh in 2002. All 
contractual items on the systems have been accepted with the
exception of four water level monitoring sites that are located at
reservoirs.  The Government of Andhra Pradesh believes that 
the sites should go down approximately 100 meters at the sites.
The Company does not believe that it is required to provide 
monitoring at 100 meters due to lack of specification in the
Request for Proposal (RFP) and the Company's proposal that
specified 10 meters at each site.  This matter will most 
likely be referred to an arbitrator as per provisions of the 
contract.  In the event that the Company loses the arbitration
hearing, additional costs of approximately $120,000 will be 
incurred to install the sites down to 100 meters.
 


ITEM 4 - SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

No matter was submitted during the fourth quarter of 2004 to a

Fiscal 2004 Compared to Fiscal 2003

Results of Operations

The Companys revenues for 2004 increased 51% to $16.7 million from $11 
million in 2003. The Company derives its revenues from the sale of products
consisting primarily of dataloggers, satellite transmitters/loggers and sensors,
integrated systems, hydrological services consisting primarily of equipment 
installation and maintenance and engineering services and airport weather
systems.  

Revenues from sales to domestic customers increased in 2004 to $11.3 million
from $7.9 million in 2003, an increase of 42%. Standard products sales
increased to $6.96 million in 2004 from $5.65 million in 2003. Revenues 
from integrated systems, which includes special projects and the Companys
branch office in India, increased significantly to $1.95 million compared
to $1.3 million in 2003 primarily due to increased software services projects
and engineering services provided to Hanscom Air Force Base to develop the
AN-FMQ-13(V)2 wind sensor system.  Revenues for hydrological services 
increased to $2.36 million from $1 million in 2003 due to the expansion
of operations in Florida.  

Revenues from international sales increased 74% to $5.4 million in 2004
from $3.1 million in 2003.  Sales of products increased to $3.73 million
from $944 thousand in 2003 due to the Company providing dataloggers,
sensors and other equipment totaling $2.4 million to a Canadian consortium
for a flow monitoring and flood warning system in Poland. Revenues from
integrated systems, which includes special projects and the Companys branch
office in India, decreased to $1.7 million from $2.0 million due to fewer
international systems projects.  Revenue from airport weather systems, a
division started in 2003, declined to $8 thousand in 2004 from $70 
thousand in 2003.

The Companys largest customer in each of years 2004 and 2003 was the
Department of the Interior, the principal agencies being the US Geological
Survey and the Bureau of Reclamation, which accounted for 20% and 28% of
revenues, respectively.  Non-federal government, commercial and international
revenues represented 56% of revenues in 2003 versus 55% in 2002.

  ------------------------------------------------------------------------ 


Gross Profit

Gross profit for 2004 increased 90% to $6.43 million from $3.36 million in
2003.  Gross profit as a percentage of revenues for 2003 increased to 38.5%
as compared to 30.5% in 2003.

Gross profit improved in 2004 due to the increase in revenues and due to
improvements in the design and manufacturability of the SatLink 2 Satellite
Transmitter/Logger.  The Company certified the Satlink2 in January 2004 
and began shipping units in May 2004.  The SatLink2 was designed to have
fewer parts, improved manufacturability and improved features compared 
to the SatLink . The Company also benefited from large project awards with
Hanscom Air Force Base and a Canadian consortium for a flow monitoring
and flood warning system in Poland.  Both contracts required significant
quantities that allowed the Company to obtain supplier pricing discounts 
that greatly improved margins.  The Companys gross margin is dependent on
product volumes, product mix, overhead expenses and projects that vary in 
terms of size, complexity and pricing competitiveness.   All of these factors
fluctuate from year to year.  

Selling, General and Administrative Expenses

Selling, general and administrative expenses were $2.4 million in 2004 as 
compared with $2.2 million in 2003.  Selling, general and administrative 
expenses as a percentage of revenues decreased to 14.4 in 2004 from 20.1% in
2003 due to the increase in revenues.
                                     

Research and Development Expenses

Research and development expenses decreased 4% to $1.02 million in 2004 from
$1.06 million in 2003.  Research and development expenses as a percentage of
revenues decreased to 6.1% in 2004 from 9.7% in 2003.  In 2004, engineers
worked directly on certain contracts including the Hanscom Air Force Base 
AN-FMQ-13(V)2 Wind Sensor System resulting in engineering costs being included
in cost of sales. 

In 2004, the Companys product development focus was on continual improvement
of the SatLink2 and other core products.  The Company certified the SatLink2
to operate on Chinas environmental satellite, FY-2C.  The Company expects China
to be a significant market.  The Company also worked towards certification of
a 40 Watt SatLink2 Satellite Transmitter/Logger that can be installed on 
existing and new ocean system buoys to send ocean and weather parameters 
including tsunami warnings through the global geostationary satellite systems 
in near real-time. Certification of  the 40 Watt SatLink2 Satellite 
 Transmitter/Logger was received from NESDIS in March 2005.

The Company continued its development efforts in 2004 relating to tides
monitoring systems by adding Storm Surge/Tsunami software.  Tides systems
are based on the Xpert datalogger and the SatLink2 transmitter.  The Company
received orders for tides systems totaling $900 thousand in 2004 and $676
thousand in 2003.  The Company expects a significant increase in revenue
from tides systems in 2005 due to increased funding by the federal government
for tide monitoring and tsunami warning systems.

Other Income (Expense)

Other income and expenses consisted of interest expenses of $30 thousand
in 2004 and 2003.  

Fiscal 2003 Compared to Fiscal 2002

Results of Operations

The Companys revenues in 2003 increased 8% to $11 million from $10.2 million
in 2002. The Company derives its revenues from the sale of standard products 
consisting primarily of dataloggers, SatLink transmitters and sensors, 
systems and software that are done on a project specific basis, hydrological and
engineering services and airport weather systems.  

Revenues from sales to domestic customers increased in 2003 to $7.9 million from
$7.25 million in 2002, an increase of 8.7%. Standard products sales increased 
slightly to $5.65 million in 2003 from $5.6 million in 2002. Revenues from 
integrated systems and software were down $256 thousand to $1.3 million from 
$1.56 million.  Revenues for hydrological services increased to $992 thousand 
from $110 thousand in 2002 due to the expansion of operations in Florida and 
winning five major multi-year contracts in 2002 and 2003 with the South Florida 
Water Management District.  

Revenues from international sales increased slightly to $3.1 million in 2003 
from $2.95 million in 2002.  Standard products decreased to $944 thousand 
in 2003 from $1.3 million in 2002 due to decreased sales from China. Revenues 
from integrated systems and software were up $400 thousand to $2.0 million from 
$1.6 million due to several large projects including a $499 thousand
project to provide a rainfall measuring system to the government of Morocco, a
$730 thousand World Meteorological project to provide airport meteorological 
systems to 13 small island states in the Caribbean and a $446 thousand standard 
product order from a hydropower company in Venezuela. The Company sold its first
airport weather system in 2003 and realized revenue of $71,000.

The Companys largest customer in 2003 and 2002 was the Department
of the Interior, the principal agencies being the US Geological Survey and the 
Bureau of Reclamation, which accounted for 28% and 26% of revenues.
Commercial and international revenues represented 55% of revenues in 2003 versus
48% in 2002.

  ------------------------------------------------------------------------ 


Gross Profit

Gross profit for 2003 decreased 2.7% to $3.36 million from $3.45 million
in 2002. Gross margin as a percentage of revenues for 2002 decreased to
30.5% as compared to 33.8% in 2002. Increased sales of SatLink 
transmitters caused a decrease in the Companys margins.  The Companys
new SatLink transmitter, the SL2-G312-1, was certified in January 2004
and will significantly improve future margins due to fewer parts
and improved manufacturability.  The Companys margins were also
impacted by three projects that were awarded in 2002.  Two projects
were with the Government of Andhra Pradesh of India and one project
was with the Meteorological Service of Mexico.  All three projects were
bid very competitively.  The company completed the Mexico project in
2003. The Government of Andhra Pradesh projects are near completion.
The Company anticipates that these projects will be completed in mid
2004.  The Companys gross margin is dependent on product and system
costs, product mix and overhead expenses, all of which fluctuate from
year to year.  

Selling, General and Administrative Expenses

Selling, general and administrative expenses were level at $2.2 million
in 2003 and 2002. Selling, general and administrative expenses as a 
percentage of revenues decreased to 20.8% in 2003 from 21.8% in 2002 
due primarily to the increase in sales.

Research and Development Expenses

Research and development expenses decreased 28% to $1.06 million in
2003 from $1.48 million in 2002.  Research and development expenses
as a percentage of revenues decreased to 9.7% in 2003 from 14.5% in
2002.  The primary reason for the decrease  was the completion of
Xconnect systems software.  Upon its completion in late 2002, the
Company transferred several software engineers into direct departments
in order to provide customers with systems and   application development
services. 

In 2003, the Companys product development focus was on the design and
certification of the SatLink2 in order to enhance the product and 
improve margins.  The SatLink2 is a high data rate satellite 
transmitter that transmits at 100, 300 and 1200 baud, 
incorporates GPS and functions as a logger as well.  All GOES 
satellite customers are mandated by NESDIS to purchase high data rate
satellite transmitters and to replace all old 100 baud transmitters
within a ten-year period effective July 2001.  The Company 
believes that the SatLink2 will allow it to dominate the replacement
market.

In 2003, the Company continued its development efforts relating to
tidal monitoring  applications by introducing enhancements to its
tides monitoring systems.  The tides systems are based on the 
Xpert and XLite dataloggers and use the SatLink transmitter.
The Company won orders totaling $663 thousand in 2003 and  $450
thousand in 2002 for tides systems.  The Company also completed
the development of an analog expansion module in 2003.

Other Income (Expense)

Other income and expenses consisted of interest expenses of $30
thousand in 2003 compared with $47 thousand in 2002.  

Liquidity and Capital Resources

The Companys working capital was $5.35 million at December 31, 2004
compared with $3.4 million at December 31, 2003.  Cash on hand was 
$1,419,171 at December 31, 2004 compared to $388,612 at December 31, 2003.  
Of the cash balance on hand at December 31, 2004, $277,454 was restricted 
and served as collateral for international standby letters of credit and 
$108,568 was restricted and served as bid bonds on international tenders.	

Net cash provided by operating activities was $2,133,859 for the year ended 
December 31, 2004 as compared to cash used by operating activities of 
$526,355 for the year ended December 31, 2003 and cash provided by operations 
of $853,560 for the year ended December 31, 2002.  

Net cash used in investing activities was $213,709 for the year ended 
December 31, 2004, compared to $156,983 and $61,698 for the years ended 
December 31, 2003 and 2002, and was primarily due to purchases of property 
and equipment.

Net cash used by financing activities was $893,740 for the year ended 
December 31, 2004 due to payments on the line of credit and on shareholder 
and term notes. Net cash provided by financing activities was $670,210 for 
the year ended December 31, 2003 due to proceeds from the line of credit and 
shareholder notes.  Cash used by financing activities was 493,098 for the year 
ended December 31, 2002 due to payments on the line of credit and term notes.

The Company has a revolving credit facility of $1,625,000 with BB&T Bank.  
The credit facility expires on August 5, 2005. Management believes that 
its existing cash resources, cash flow from operations and short-term 
borrowings on the existing credit line will provide adequate resources for 
supporting operations during fiscal 2005.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


To the Board of Directors and Stockholders
Sutron Corporation
Sterling, Virginia


	We have audited the accompanying balance sheets of Sutron 
Corporation as of December 31, 2004 and 2003, and the related 
statements of operations, stockholders' equity, and cash flows 
for each of the three years ended December 31, 2004.  These 
financial statements are the responsibility of the Corporation's 
management.  Our responsibility is to express an opinion on these 
financial statements based on our audits.

	We conducted our audits in accordance with the standards of 
the Public Company Accounting Oversight Board (United States).
Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free
of material misstatement.  An audit includes examining, on a test 
basis, evidence supporting the amounts and disclosures in the 
financial statements.  An audit also includes 
assessing the accounting principles used and significant estimates 
made by management, as well as evaluating the overall financial 
statement presentation.  We believe that our audits provide a 
reasonable basis for our opinion.

	In our opinion, the financial statements referred to above 
present fairly, in all material respects, the financial position 
of Sutron Corporationas of December 31, 2004 and 2003, and 
the results of its operations and its cash flows for each 
of the three years ended December 31, 2004, in conformity with
generally accepted accounting principles.

SUTRON CORPORATION

NOTES TO FINANCIAL STATEMENTS

(1)  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Nature of Business

Sutron Corporation ("the Company") was incorporated
on December 30, 1975 under the General Laws of the 
Commonwealth of Virginia.  The Company operates from its
headquarters in Sterling, Virginia.  The Company has several 
branch offices located throughout the United States and a branch 
office in India.  The Company is a leading provider of real-time
data collection and control products, systems software and 
professional services in the hydrological and
meteorological monitoring markets.  The Company's products include
dataloggers, satellite transmitters/loggers, sensors and
systems and applications software.  Customers include a diversified
base of Federal, state, local and foreign governments,
universities, engineering firms and hydropower companies.

Revenue Recognition

The Company utilizes the accrual method of 
accounting for both financial statement and tax
 return reporting purposes.  The Company recognizes
 revenue from product sales upon shipment.  Selling,
 general, and administrative expenses are charged
 against periodic income as incurred.  Revenue 
from cost-plus-fee contracts is recognized to the
 extent of costs incurred, plus a proportionate
 amount of fees earned.  Revenue from fixed-price
 contracts is recognized on the 
percentage-of-completion method based on costs 
incurred in relation to total estimated costs. 
 Revenue from time-and-materials contracts is 
recognized to the extent of billable rates, times 
hours delivered, plus materials costs incurred.  
Contract costs include allocated indirect costs 
and general and administrative expenses.  
Anticipated losses are recognized as soon as 
they become known.

Cash and Cash Equivalents

For purposes of the statements of cash flows, cash 
equivalents include time deposits and all highly liquid
debt instruments with original maturities of three months
or less.  Interest paid amounted to $32,489, $27,859, and
$48,936 in 2004, 2003 and 2002, respectively.  Income
taxes paid amounted to $600,000 in 2004.  No income taxes
were paid in 2003 and 2002.

The Company has entered into international contracts that require
standby letters of credit.  Certain standby irrevocable letters of 
credit issued by the Company's previous bank shall expire in March 
2005.  At December 31, 2004, $277,454 of the cash and cash equivalents
balance is restricted for these standby letters of credit that were
issued by the Company's previous bank. During the year, the Company
submitted contract proposals that required bid bonds or bank guarantees
in the form of a certified check.  At December 31, 2004, $108,568 of 
the cash and cash equivalents balance is restricted for these bid bonds. 
 
Inventory

Inventory is stated at the lower of cost or market.  Electronic components
costs, work in process and finished goods costs consist of materials, labor 
and overhead and are recorded at a standard cost that approximates the 
average cost method.

Accounts Receivable

Based on managements evaluation of uncollected accounts receivable at 
the end of each year, bad debts are provided for utilizing the allowance 
method.  The allowance for doubtful accounts as of December 31, 2004 and
2003 approximate $32,100 and $10,000, respectively.  At December 31, 2004
and 2003, the Companys investment in accounts 90 days or more past due 
is $434,818 and $175,950, respectively, net of contract retainages.  

Property and Equipment

Equipment is recorded at cost and depreciated over their estimated useful 
lives, ranging from 3 to 7 years, using the straight line method for
financial statement purposes, and the straightline and accelerated 
methods for income tax purposes.  Expenditures for maintenance, repairs, 
and improvements that do not materially extend the useful lives of the 
assets are charged to earnings as incurred.  When items of property, plant,
and equipment are disposed of, the cost of the asset and the related 
accumulated depreciation are removed from the accounts.  Any gain or 
loss resulting from the removal from service is taken into the current 
period earnings.

Income Taxes

The Company utilizes an asset and liability approach to accounting for 
income taxes.  The objective is to recognize the amount of income taxes 
payable or refundable in the current year based on the Companys income 
tax return and the deferred tax liabilities and assets for the expected 
future tax consequences of events that have been recognized in the 
Companys financial statements or tax returns.  The asset and liability 
method accounts for deferred income taxes by applying enacted statutory 
rates to temporary differences, the difference between financial statement 
amounts and tax bases of assets and liabilities.  The resulting deferred 
tax liabilities or assets are classified as current or noncurrent based 
on the classification of the related asset or liability.  Deferred income 
tax liabilities or assets are adjusted to reflect changes in tax laws or 
rates in the year of enactment.

Foreign Currency Translation

Results of operations for the Companys foreign branch office are translated 
from the designated functional currency to the U.S. dollar using average 
exchange rates during the period, while assets and liabilities of the 
foreign branch office are translated at the exchange rate in effect at the 
reporting date.  Resulting gains or losses from translating foreign currency 
financial statements are included in other comprehensive income, net of any 
related tax effect.

Financial Instruments

The estimated fair value of cash and cash equivalents, accounts 
receivable, accounts payable and accrued expenses and short term notes 
payable approximate their carrying amounts in the financial statements.
Based on the borrowing rates currently available to the Company for debt 
with similar maturity dates and collateral, the estimated fair value of 
longterm debt is $90,000 and $100,000 at December 31, 2004 and 2003,
respectively.

Use of Estimates

The preparation of financial statements in conformity with accounting 
principles generally accepted in the United States of America, requires 
management to make estimates and assumptions that affect the reported 
amounts of assets and liabilities and disclosure of contingent assets 
and liabilities at the date of the financial statements and the reported 
amounts of revenue and expenses during the reporting period.  Actual 
results could vary from the estimates that were used.

Capital

The Company has 12,000,000, $.01 par value, shares authorized.  There 
were 4,289,551 shares issued and outstanding at December 31, 2004, 2003
and 2002.  The Companys Board of Directors has authorized the repurchase
of up to 100,000 shares of its common stock in open market transactions.  
As of December 31, 2004, 13,800 shares have been repurchased.

Earnings Per Share

The Company has adopted Statement of Financial Accounting Standards (SFAS) 
No. 128, which establishes standards for computing and presenting earnings 
per share (EPS) for entities with publicly held common stock.  The standard 
requires presentation of two categories of earnings per share, basic EPS 
and diluted EPS.  Basic EPS excludes dilution and is computed by dividing 
income available to common stockholders by the weighted average number of 
common shares outstanding for the year.  Diluted EPS reflects the potential 
dilution that could occur if securities or other contracts to issue common 
stock were exercised or converted into common stock or resulted in the 
issuance of common stock that then shared in the earnings of the Company.  

Stock Compensation Plans

At December 31, 2004, the Company had three stock-based employee compensation
plans, which are described more fully in Note 12.  The Company accounts for
its stock-based employee compensation plans under the recognition and 
measurement principles of Accounting Principles Board (APB) Opinion No. 25,
"Accounting for Stock Issued to Employees," and related interpretations.
APB No. 25 provides that compensation expense relative to a companys employee
stock options is measured based on the intrinsic value of the stock options
at the measurement date.

In December 2004, the FASB issued SFAS No. 123 (revised), "Share-Based 
Payment".  SFAS No. 123R eliminates the intrinsic value method under APB
25 as an alternative method of accounting for stock-based awards.  SFAS
NO. 123R also revises the fair value-based method of accounting for share-
based payment liabilities, forfeitures and modifications of stock-based
awards and clarifies the guidance of SFAS No. 123, "Accounting for Stock-
based Compensation," in several areas, including measuring fair value, 
classifying an award as equity or as a liability and attributing 
compensation cost to reporting periods.  In addition, SFAS No. 123R amends
SFAS No. 95, "Statement of Cash Flows," to require that excess tax benefits
be reported as a financing cash inflow rather than as a reduction of taxes
paid, which is included within operating cash flows.

The Company is required to adopt SFAS No. 123R for the interim period beginning
December 15, 2005, using one of three implementation alternatives specified
under SFAS No. 123R.  The Company is currently in the process of determining
which implementation alternative to use and what the expected financial impact
of SFAS No. 123R may be.

If compensation expense had been recorded based on the fair value of awards
under the stock option and purchased plans set forth in SFAS No. 123, as 
amended, the Company's net income (loss) attributable to common stockholders
would have been adjusted to the pro forma amounts presented below, for the 
years ended December 31:
