Wind Speed and Direction Detection Device Based on Annular Wind Tunnel

This paper mainly introduces the wind speed and wind direction detection device based on the annular wind tunnel. The device consists of two parts, which are the wind speed detection part with the standard pitot tube as the standard device and the wind direction detection part with the standard dial as the standard device. Through the analysis of the principle, detection method and uncertainty of the wind speed and wind direction detection device, it shows that the device has high accuracy and good reliability in the measurement of wind speed and wind direction.
