WA15
Wind set with cup anemometer and wind vane
A high-performance wind measurement set with an industry-standard track record in meteorological applications. It combines the WAA151 cup anemometer — fast response, low starting threshold, and excellent linearity up to 75 m/s — with the counter-balanced optoelectronic WAV151 wind vane, mounted on a common cross-arm. Shaft heating in both sensors keeps the bearings operational in cold climates.
