Abstract：According to the needs of regular calibration of AG2 ultrasonic evaporation sensor of national automatic weather station in Jilin province,this paper introduces the system structure,wiring principle and measurement performance index of evaporation sensor.The experimental analysis is carried out and field calibration methods are studied.The experimental results show that the method of using digital multimeter to read the measured value is better than the value obtained by the station ground comprehensive observation business software and the detection speed is faster.This method is feasible in field calibration and provides theoretical support for the revision of the verification regulation of evaporation sensor in automatic weather station.
