Abstract：Flowmeters are widely used in coal mine safety production，its performance field testing in the development，manufacture and use. This purpose，the paper application of virtual instrument technology research and development of a set of water flow standard device，a detailed discussion of the hardware configuration and software design flow standard device，and gives the measurement uncertainty of water flow standard device. After hundred sets of various types of flowmeter for inspection and testing，operation results show that the water flow standard device detection system is stable and reliable，high test efficiency，certain practical value and popularization significance.
