Analysis of Flow Ratio Measurement Rate of Shuibao Hydrological Station
In order to find out whether the observation data of radar wave flow measurement system in Shuibao hydrological station meet the requirements of flow observation standard.Collect manual measurement data and radar wave flow measurement system observation data,draw the water level-flow relationship curve,and carry out three tests to collect the measured data of flow ratio measurement;the measurement error of radar wave current measurement system is studied by using random uncertainty calculation formula and system error analysis.The results show that the test results of the water level-discharge relationship curve are reasonable and meet the requirements of the code;the calculation results of system error and random uncertainty meet the requirements of the specification,and the flow rate measured by the radar wave flow measurement system is better than that measured by manual measurement.The radar wave flow measurement system can be popularized in Shuibao station,which realizes the automation and digitization of flow data transmission.The application of the flow measurement flume in the station has improved the accuracy of low water flow measurement,which can provide technical support for the further promotion of the flow measurement flume in the river.
