Product information "Starting threshold - Cup Anemometer"
Measurement in accordance to ISO 17713-1. The starting threshold will be determined by measuring the lowest wind speed at which the cups of the anemometer start to continuously turn and the anemometer is producing a measurable output signal. The anemometer is mounted with a tilt angle of 0 deg. During the measurements, the tunnel speed is slowly increased from 0 m/s upwards. This procedure is performed several times whereas the initial position of the cups is varied by approximately ten degrees for each run. Minimal flow speed approximately 0.2 m/s.
