It uses ultrasonic technology to measure the air velocity. The detection head consists of a single transmitter and a row of two receivers. When the wind direction is the same as the arrow direction, the transmission time of A will increase with the increase of wind speed, and the transmission time of B will increase with the increase of wind speed. The wind speed increases and decreases. The wind direction is opposite to the arrow direction. The transmission time of A decreases and the transmission time of B increases. According to the phase difference of the ultrasonic signals received by the two receivers, the wind speed and direction can be calculated.
