Abstract In the traditional measuring bench of centrifugal pump the means of measuring was lagged,the speed was slow,and the accuracy was insuffient.To solve the above problems,an auto-measuring system based on RS485 Bus was developed.The system could realize the performance and cavity tests which include the auto-control of valve and vacuum pump,real-time data acquisition,data processing and saving,plotting and getting the report of testing.The result of experiment show that the system make up for the fault in the traditional measuring system,and has features that the degree of automatization is high,the accuracy is suffient and measuring speed is quick.centrifugal pump;performance test;auto-measuring; RS485
