Wind Professional 100 3-axis Ultrasonic Anemometer

The Wind Professional 100 ultrasonic anemometer is a rugged, high quality, low cost ultrasonic anemometer for the measurement of both horizontal and vertical wind flow. The optimal design with three outer paths of measurement around a middle bar minimises flow distortions and with unique, sophisticated quality checks for each instantaneous measurement ensures extreme accuracy and reliability.

The Wind Professional 100 ultrasonic anemometer is suitable for environmental systems for buildings and structures, for bridge monitoring, for basic 3 component wind monitoring, for pollution monitoring and as a reference instrument.

The anemometer has no moving parts, no calibration requirements and is easily connected to a computer or data logger using a digital output.

What it does

The Wind Professional 100 provides the following information in various data outputs which can be polled or output automatically:

• instantaneous and averaged data for the three component wind vectors
• virtual temperature
• horizontal wind speed and direction plus vertical wind component
• chart mode (provides 0-540º wind direction and speed values)
• NMEA value outputs
• raw data mode (uncorrected) or 2D / 3D head corrected data

Data can be averaged by:

• scalar or vectoral
• clock synchronised or running average
• separate output rates and sampling times

Some other important features:

• user definable north orientation (range 0-359º alignment off axis)
• data quality control to perform confidence checks on raw data
• date / time stamps with several options
• check sum information
• calibration validity output monitoring

Examples of data output

Normal data example (instantaneous). Every data string starts with a header line that consists of the string SNC followed by a space and 12 characters for the date/time stamp, another space and finally the UTC string i.e.:

SNC 940815090015 UTC

x = 1.83 y = -0.79 z = 0.20 T = 20.17



where:

x	mean x wind component in the sensor related orthogonal co-ordinate system (parallel to the black arrow on the electronic box); unit m/s
y	mean y wind component in the sensor related orthogonal co-ordinate system (horizontally perpendicular to x); unit m/s
z	mean z wind component in the sensor related orthogonal co-ordinate system (vertical); unit m/s
T	mean temperature; unit ºC
