XF200L Ultrasonic Wind Speed and Wind Direction Sensor is a measuring instrument that uses the time difference of ultrasonic wave in the air to measure the wind speed and direction. Compared with the traditional mechanical anemometer, it has the characteristics of minor abrasion, long service life, and fast response. It can be widely applied into urban environmental monitoring, wind power generation, meteorological monitoring, bridges and tunnels, navigation ships, aviation and airports and other fields. No maintenance and field calibration required.
