Wind direction indicators – Wind vanes – Two and three axis ultrasonic anemometers (direction)

The wind vane anemometer also called Anemoscope is used to indicate the wind direction. It is normally used together with a cup anemometer, and in some cases, they are coexistent in the same instrument body.

In the Wind Measurement Laboratory, it is possible to issue a calibration report on the measurement of the wind direction of wind vane anemometers but also of biaxial and triaxial ultrasonic anemometers. The procedure is carried out by measuring, at known angles intervals, the wind direction indicated by the anemometer under calibration.
