Product Description

Ultrasonic anemometers measure the horizontal wind speed and direction as well as the temperature. The Ultrasonic Anemometer 3 D serves for the measurement of the wind direction and the wind velocity from all spatial directions. The maintenance-free anemometer needs no re-calibration, and can be 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.
