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。
Introduced the multichannel ultrasonic flowmeter in Siyang station of the East Route of South to North Water Diversion Road and the use of the sound path, and combined with the unit model test to prove its accuracy, the maximum error of 0.52%, indicating that the multi-channel ultrasonic flowmeter completely It can meet the engineering requirements of Siyang Station. Combined with the forward and reverse model test of flow measurement, it provides a reference for the installation location, sound path selection and measurement accuracy of multi-sound path ultrasonic flowmeter in the Eastern Route Pumping Station of South-to-North Water Diversion Project.
