Abstract：An approach for measuring pump set characteristics was presented to change the status that the pump system characteristic calculated by the empirical formula was not exact.The formula of the pump set pipeline characteristic was derived by means of the energy equation of the inhalation of water-absor-bent cross-section tube,pump intake cross-section,pump outlet cross-section and the cross-section of valves.Therefore,the actual characteristics of pump setting could be easily calculated through measuring the relevant parameters in the formula to determine the pipeline losses,the pressure at the end of device and the upgrade elevation when the flow was being regulated by the inverter.In the measurement system which is composed of the virtual instrument and the LabVIEW,the automatic testing of the pump set characteristics is realized easily by inputting the relevant data in the program.The pump set characteristic curve was measured by use of the testing system and was basically consistent with the calculated value.
