Research and Application of Verification Device for Rain Gauge
Based on the principle of mass measurement and volume conversion,this paper proposes the design of the opening and closing signal by accurately measuring and controlling the quality and time of the water supply unit.A rain gauge verification device is developed to realize the traceability of the rainfall value in the water conservancy industry.After evaluating the measurement uncertainty of the verification results,it is proved that the device meets the design requirements.Compared with the traditional manual verification method,the device avoids the uncertainty factors brought by manual operation,improves the verification accuracy,and uses the computer to control the whole process of verification to realize the automatic verification and improve the efficiency with a good application prospect.
