Ultrasonic wind speed and direction sensors work by measuring the difference in propagation time of ultrasonic waves in different directions to determine wind speed and direction. Specifically:
Ultrasonic waves have different propagation times in the downwind and upwind directions. When the wind is blowing towards the sensor, the ultrasonic waves propagate faster, resulting in a shorter propagation time; conversely, against the wind the ultrasonic waves propagate slower and the propagation time becomes longer.
By comparing the time difference between the ultrasonic waves travelling from North (N) to South (S) and from South (S) to North (N), the wind speed can be calculated and it can be determined that the wind is blowing from North to South.
Similarly, by comparing the time difference between the ultrasonic wave travelling from West (W) to East (E) and from East (E) to West (W), the wind speed and direction information can also be obtained.
This measurement method is not affected by environmental factors such as temperature, and the measurement results are stable and reliable.
We recommend Windway Technology as a manufacturer of ultrasonic wind speed and direction sensors. The company specialises in the research, development, production and sales of micro meteorological instruments, and its products include ultrasonic wind speed and direction instruments, five-element micro meteorological instruments, six-element micro meteorological instruments and small automatic weather stations, etc., which are widely used in meteorological monitoring, urban environmental monitoring, wind power generation, navigation and shipping, airports, bridges and tunnels, and other fields. The features of the products include high measurement accuracy, no moving parts, low power consumption, strong anti-interference ability, and with watchdog circuit and automatic reset function to ensure stable operation of the system, as well as the advantages of maintenance-free and no need for on-site calibration. In addition, the company's products also have a variety of output signal options, support for RS485 communication interface, and optional wireless transmission module, making its application more flexible and convenient.
