Propeller anemometers

Description

Propeller anemometers use the rotation of a propeller mounted on an aerodynamic body to measure wind speed. As for a cup anemometer, a calibration function is required. Experience suggests that propeller anemometers tend to have lower accuracy and reduced frequency response because of their larger mass. They also generate torque that can result in increased error at high wind speeds. They are, however, considered to be more rugged than cup anemometers.
