Abstract
Flow standard device not only is the reference and transferring of flow unit value, but also is widely used as experimental device .The research and application of it is an important link in the development of flow measurement and test technology. In view of the characteristics of industrial application fields, A set of "standard and combined" water flow device is researched and designed in the paper. The device will be static weight method and the standard meter method gives reasonable collocation from system scale and uncertainty synthesis, it can realize the verification and experimental studies of various velocity type flowmeter has the characteristics of high verification efficiency, low cost and high automation. More than flow meters have been calibrated on the device. It is confirmed by the operation status and the experimental data that every technology criterion has reached the design requirements, and it proved is reasonable to the design scheme about water flow standard device of master meter and static weight method.
