Key Benefits

Anemometer with excellent linearity
The WAA151 is a fast response, low-threshold anemometer. Three lightweight, conical cups mounted on the cup wheel, provide excellent linearity over the entire operating range, up to 75 m/s.
Sensitive wind vane
The WAV151 is a counter-balanced, low-threshold, optoelectronic wind vane. Infrared LEDs and phototransistors are mounted on six orbits on each side of a 6-bit GRAY-coded disc. Turned by the vane, the disc creates changes in the code received by the phototransistors.


Long and successful track record in meteorological applications
Low measurement starting threshold
Conical anemometer cups provide excellent linearity
Heated shaft prevents bearings from freezing
