【Abstract】 The paper summarizes the traditional methods of flow measurement and brings forward another method using build-in 7510 portable ultrasonic flowmeter, it is effective to use the meter to measure the discharge of a single pump in low lift and large flow rate pump station. The working principle, performance and installation of build-in 7510 portable ultrasonic flowmeter were described. The pump discharge of Jiangdu second pump station of the South-North Water Project was made and the uncertainty of the measurement results was analyzed.更多还原
