Ultrasonic wind direction anemometer is an instrument that utilizes ultrasonic technology to measure wind direction and wind speed. It measures the information such as time difference or phase difference of ultrasonic wave propagation in the air through ultrasonic sensors arranged at different locations, and then calculates the wind speed and direction.

The instrument has the following distinctive features:

High measurement accuracy: it can provide more accurate wind direction and wind speed data.

Fast response speed: it can quickly capture the change of wind direction and wind speed.

Good stability: less interference by environmental factors, stable working condition.

No need for maintenance: there are no movable parts, reducing the maintenance workload.

Strong adaptability: it can work normally under a variety of harsh environmental conditions.


Ultrasonic wind anemometers have important applications in the fields of meteorological monitoring, aerospace, navigation, wind power generation, etc., which provide key wind direction and wind speed information support for research, decision-making and operation in related fields.
