Application for Ultrasonic Wind Sensor:
anemometers work on the principle that the travel time of sound waves through air is affected by the wind speed component parallel with the direction of travel. The basic element of a sonic anemometer consists of an ultrasonic sound emitter and receiver at opposite ends of a sampling volume.It works by the rotation of the arrow of the wind direction, and transmits it to the coaxial code plate, at the same time outputs the relevant values of the wind direction. Usually the main body of the wind direction sensor adopts the mechanical structure of the wind vane.
