Abstract The rainfall sensor needs to be calibrated and maintained regularly to ensure the accuracy of the data when there are errors in the calibration.Combined with the principle of the rainfall sensor,the concept of “Flow at the Turn” has been put forward in this paper.A lot of analysis to the conventional errors and the adjusting method in the rainfall sensor calibration are discussed.Aiming at the particular situation that the heavy rain is bigger than the standard data and the light rain is less,according to the experimental data,a solution is provided that the results of heavy rain can be corrected by the light rain.This scheme is feasible and can effectively solve the adjustment problem of SL2-1 rainfall sensor.
