AG2.0型超声波蒸发传感器应用及检定方法研究

Application and calibration method of AG2.0 ultrasonic evaporation sensor

文章从AG2.0型超声波蒸发传感器的系统结构和工作原理出发,详细介绍了该传感器的测量环境和技术参数,分析了业务应用的正确方法。根据实际检定工作,研究了AG2.0型超声波蒸发传感器的检定方法,展示了蒸发传感器现场检定实例。结果表明:由于测量环境的改变,AG2.0型超声波蒸发传感器测得的蒸发水位比实际值偏小,需将蒸发水位订正1.019的系数;检定中,注意蒸发零位值、检定和数据处理方法的变化,避免引起检定结论误判。

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.
