A rotating vane anemometer measures airflow through mechanical velocity. Airflow passes over the propeller of the vane anemometer, causing rotational motion. The speed of rotation is then converted into a value for airflow speed. Vane anemometers can typically measure airflows in a range of 1 m/s to 15 m/s. Speeds below this range are too low ...
