Abstract:Based on the system structures and working principles of the AG2.0 ultrasonic evaporation sensor,the measurement environment and technical parameters of the sensor are introduced in detail,and the correct method of business application is analyzed.According to the actual verification work,the verification method of the AG2.0 ultrasonic evaporation sensor is studied,and an example of on-site verification of the evaporation sensor is demonstrated.The results show that due to the change of measurement environment,the evaporation water level measured by AG2.0 ultrasonic evaporation sensor is smaller than the actual value,and the evaporation water level needs to be corrected by 1.019 coefficient.During the verification,the changes of evaporation zero value,verification and data processing methods should be paid attention in order to avoid causing misjudgment of the verification conclusion.
