Ultrasonic Wind Sensor Application:
An ultrasonic anemometer is a common instrument at a weather station. It is used to measure the wind speed and wind direction. The most common type of anemometer uses mechanical sensors consisting of three or four hemispherical cups mounted on horizontal arms on a vertical rod. As the wind blows, the cups are pushed causing the arms to rotate at a rate proportional to the wind speed. In addition, a wind vane connected to the anemometer can give the direction measurements. While the cup and vane anemometers are very popular due to their very simple design, they can be susceptible under cold and humid conditions because of their mechanical rotating parts, possibly causing the turbine to stop operating during extreme conditions. Designed without any moving parts, the ultrasonic anemometers are more reliable, maintenance free, long-lasting, and can operate in challenging weather conditions. In this article, we will review the basic working principle of an ultrasonic anemometer, and discuss about some versions of ultrasonic anemometers reported by makers on the internet.
