Comparison of measured data

We conducted a comparative experiment for six months on three types of sensors: XFC2-2H, propeller type of American Y brand, and Ultrasonic type of Finnish V brand. One month's wind speed measurement data is shown in the figure. The consistency of the data measured by the three wind speed sensors is good. The wind sensor of propeller tail type requires an adjustment cycle to make the windward surface to catch up with the wind direction, and accurate wind speed values can be only measured when the propeller is facing the windward surface. Taking the comparison data as a reference, due to the lower starting values of wind speed and wind direction, the wind speed response of XFC2-2H was significantly faster.
