Ultrasonic wind speed and direction meter principle, technical parameters

The principle of ultrasonic wind speed and direction meter is to use ultrasonic time difference method to achieve the purpose of wind speed and direction measurement. The speed of sound propagation in the air is iterated with the speed of airflow in the wind direction. If the ultrasonic propagation direction is equal to the wind direction, then its speed is faster; Conversely, if the ultrasonic propagation direction if equal to the wind direction, then the speed is slower. Therefore, when the detection conditions are certain, the ultrasonic propagation speed in the air can correspond to the wind speed function, and accurate wind speed and wind direction information can be obtained after calculation.

FT-WQX2 ultrasonic wind speed and direction meter is a kind of wind sensor with compact structure and high precision. It can realize accurate measurement and monitoring of wind speed and direction. Although the speed of sound waves propagating into the air is significantly affected by temperature; however, the anemometer detects information in two opposite directions in two channels, so the effect of temperature on the speed of sound waves can be ignored.

FT-WQX2 ultrasonic wind speed and direction meter is a kind of more advanced wind speed and direction measuring instrument. As it can well overcome the inherent shortcomings of the mechanical wind speed and direction meter, it can work normally in all-weather and for a long time, and thus has been more and more applications.
