█ PRINCIPLE OF ULTRASONIC WIND SENSOR
Ultrasonic wind measurement is an application of ultrasonic detection technology in gas media. It uses the influence of ultrasonic waves in air to measure wind speed by the influence of air flow (wind). Compared with the conventional wind cup or rotor type anemometer, the biggest characteristic of this measuring method is that the whole wind measuring system does not have any mechanical rotating parts, and it is a non-inertial measurement, so it can accurately measure the high frequency components of the gust pulsation in the natural wind. Combined with modern computer technology, it is of great significance to reveal the characteristics of natural wind at a higher level to improve the ability to resist wind and reduce disasters and the rational use of wind resources.
