摘　　要：介绍了多声路超声波流量计在南水北调东线泗阳站应用的测点布置和采用的声路,并结合机组模型试验证其测量精度,最大误差为0.52%,说明多声路超声波流量计完全可以满足泗阳站工程需求,同时结合流量测量正反转模型试验分析,为南水北调东线泵站多声路超声波流量计的安装位置、声路选择和测量精度确定提供参考。The application of multi-path ultrasonic flowmeter used in projector is introduced. Maximum error is 0.52%. By the pump Siyang pumping station of south to north water devotion model test report analyzed, the accuracy of multi-path ultrasonic flowmeter used on the irregular inlet passage meets the needs of the pumping station. The rules of transducers fixing section and number of path selecting are obtained, that will give a useful suggestion on the other pumping station.
