Spinner Anemometer

A spinner anemometer is an anemometer, a wind measuring instrument, that utilizes the aerodynamic flow over the spinner of a wind turbine for measurement of wind speed, yaw error and flow inclination angle to the wind turbine rotor. The components of a spinner anemometer are the wind turbine spinner, three 1D sonic sensors and an electronic conversion box. The spinner anemometer can be used for wind turbine control and verification of power performance and loads.
