Abstract：Because of the complex cross-section and flow pattern in the inlet passage of the large-scale and low-lift pumping station,it is difficult to select the reasonable section for discharge measurement.In this paper,we propose to determine the transducer installation section for ultrasonic flowmeter and to optimize the pairs of installed transducers through 3-dimensional turbulent numerical simulation of the inlet passage.Combined with pump system model test for Baoying pumping station of East Route of South-to-North Water Diversion Project,two ultrasonic flowmeters are compared with discharge testing equipment of high accuracy for hydraulic machinery.The results show that the two ultrasonic flowmeters have high precision and stability,their maximal relative errors are 1.60% and 0.39% respectively.So,these two ultrasonic flowmeters can be used to improve the precision of pump discharge measurement,which can satisfy the precision requirements in site test.
