Measurement of the wind direction and the wind velocity
in 3 dimensions X, Y, Z
• Highest precision
• Real-time measurement
• Maintenance-free / heatable
• Digital/analogue outputs and inputs
Particularly suited for the use in the fields of:
• Meteorology
• Climatology
• Aviation
• Turbulence measurement
• Immission control
The Ultrasonic Anemometer 3 D serves for the measurement of the wind direction and the wind velocity from all spatial directions. The maintenance-free and wearless anemometer needs no re-calibration, and is equipped with a heating for winter operation even under extreme conditions.
All calculations are carried out by a high-capacity digital-signal-processor (DSP) within the propagation time of the ultrasonic signals with an accuracy basis of 32 bit.
The instrument offers comprehensive statistic functions such as gliding averaging, standard deviation, co-variance etc., which can be selected via the digital interface. The gliding averaging can be set optionally in vectorial or scalar form, identically or differently for each parameter.
