INTRODUCTION: Accuracy of wind speed measurement is very important for wind energy
Why? Because windpower
is proportional to the cube of windspeed:
Wind Power(Watts)= A*V3 (v=wind speed in m/s)
So a small deviation in
wind speed (eg 0.5 m/s at 5 m/s=10 %) will result
in a deviation of Wind Power of 30%!
how about wind measurements for wind energy applications:

and environmental studies etc.
LOW COST windloggers and
Pro2 weather stations
for less demanding applications.
If higher accuracy is required (with optional calibration
certificate up to 0.1 m/s accuracy) and/or
also recording of maximum, minimum and standard deviation
(for determination of turbulence
intensity) then choose our advanced
Windlogger, which is
used for big wind energy
projects (with optional Measnet/NIST calibration certificates and

Our professional windloggers are equiped with a highly
accurate (1sec) running average filter and
16 bits AD conversion (resolution of 0.01 m/s) and still have
ultra low power consumption
(appr 100uA). Also the
possibility to use our

how about wind measurements for wind energy applications: this is
since 1983 and has been exported to over 90 countries.
ACCURACY of wind speed measurements is a KEY FACTOR for wind energy
The accuracy of the calculated
Wind Energy production from wind data:
As the Power of
a wind turbine is proportional to the cube of the
wind speed (v3),
a small deviation in wind speed will highly
affect the calculation of the energy production.
deviation of the calculated energy production is equal to:
system accuracy / average wind speed.
For example: when the yearly average wind speed is 6 m/s, measured
system accuracy of +/- 0.5 m/s, the error in the calculation
of the annual
energy production is appr. +/- 25%.
The accuracy should be in the range of 0.1- 0.2 m/s for good results of
or evaluation of the energy production of a (planned) wind energy
First Class systems are available in any configuration with
required if bank credits are used for financing wind energy projects:
- according to European MEASNET standard and according to IEC 61400-121-CD
- according to NIST standard for MAX40+ anemometer (low cost / high performance)
Expandable with meteo sensors and power transducers for power
Data processing software is available
and data processing services are available
for eg: calculation wind energy
production, determination of power curve of wind turbine etc.

More detal;ed information:
The WindOne system is designed to
provide an affordable and easy-to-use solution for wind site evaluation
wind generator power performance evluation. It easily supports both
simple and complex monitoring applications.
The WindOne system records
wind speed, gust, turbulence intensity (standard deviation/average wind
and direction, as well as the time and date, battery
voltage, and other optional important wind parameters,
like tempearture and atmospheric pressure.
The WindOne is capable of recording wind speed from one (up to eight!)
anemometers, making it ideal for
more complex studies involving multiple
wind speed instruments and other sensors.
The accuracy is excellent by using a two paremeter calibration:
slope and offset of anemometer and meets
international standards (like WMO/IEA). Optional individual calibration certificates available
resulting in an excellent 0.1 m/s accuracy.
The 16 bits conversion & calculation of values assure an unbeatable
accuracy at very low costs.
The ultra low power consumption
of appr 100 uA makes it ideal for remote applications, running at safe
battery pack (no solar panel required, also not if the wireless GPRS
option is installed!)
The WindOne records directly to a Secure
Digital (SD™) card (128MB to 2GB) to provide reliable data
An inexpensive SD™ card will store years of data at 10 min
An optional wireless GPRS internet connection is possible: receive
datafiles automatically at a server!
With optional online graphs,
Using the recorded data is simple. The SD™ card is inserted into a
card reader attached to the USB port
on your computer and will then show up as a drive.
Microsoft Excel or practically any spreadsheet program
can be used to view, graph, and analyze your wind data.
