YMCP-1型非接触微波流速仪比测试验及系数分析

Comparative Test of Noncontact Type Microwave Velocity Meter YMCP-1 and Analysis of Its Coefficient

微波流速仪系数是流量测验中用到的重要参数,其值应通过比测试验来确定。选择黄河中游府谷、吴堡两站开展微波流速仪比测试验工作;通过比测试验资料,对水面流速系数和微波流速仪系数进行了分析计算;最后对微波仪测流误差进行了分析,经计算误差满足规范要求,故其试验成果可投入生产使用。

The microwave velocity meter coefficient is an important parameter used in flow measurement. Its value must be determined by comparative test . The comparative test work of rating this coefficient is conducted in Fugu and Wupu hydrological station , which are located in midstream of Yellow River . Through test and analysing test data , the surface velocity doefficient and microwave velocity meter coefficient are calculated and analyzed , the flow mea- surement error of microwave velocity meter is analyzed too . Its error can meet the requirement of specification , the test results can be put into effect.
