Advantages of ultrasonic wind speed and direction sensors

In many fields, such as wind power generation and weather monitoring, accurate wind vector data is needed. The wind vector data are measured by mechanical anemometer and ultrasonic anemometer. Mechanical anemometer is driven by natural wind, wind cup rotation to obtain wind direction data, and wind cup rotation drives the internal axis, according to which the wind speed can be calculated. This equipment is simple in structure, low in price, has been developed for many years, has been quite perfect, but its internal rotating parts, easy to wear, will be frozen by rain and snow, blocked, and even due to rotation inertia, starting wind speed and other problems, making the data error is relatively large.

With the advancement of technology, ultrasonic anemometer has appeared on the market.

The process of ultrasonic anemometer is relatively simple, and the volume is small, easy to install and use.

It uses the principle of ultrasonic wave, ultrasonic wave is a kind of sound wave, frequency is higher than 20kHz, high frequency, short wavelength, with good directivity, the sensor made by ultrasonic wave is ultrasonic sensor.

Fengtu technology ultrasonic wind speed and wind direction sensor integrates wind speed and wind direction, no moving parts, zero wear, maintenance-free, no on-site calibration.
