專家解讀視頻
Specifies test methods of the performance of sonic anemometers/thermometers which employ the inverse time measurement for velocity of sound along differently oriented paths. Applicable to designs measuring two or three components of the wind vector within an unlimited (360 degrees) azimuthal acceptance angle.
