Abstract：Based on the theory of variety for researching a low head pump system,a new method to separate inlet conduit from pump system was put forward for measuring its hydraulic loss. Problems relative to the test device,test rule,losses calculation method and error analysis,etc. were illustrated in this paper. Compared with the traditional method,the new method has advantages of reducing expenses,shortening period and being more accurate. The new method was applied to measure the hydraulic losses of two groups of elbow inlet conduits,the geometry shape of which are different. The test results signify that the hydraulic losses of elbow conduit are relative closely to their geometry shapes.
