The Spinner Anemometer consists of three single-path ultrasonic anemometers mounted on the spinner – taking measurements while the turbine operates. Accelerometers are included so that the correct azimuth angle of the sensor in question can be determined. The device was invented and patented by Troels Friis Pedersen of Risø/Danish Technical University. On page 6 you can read the full article about the Spinner Anemometer.
