Abstract

In this paper, the evaluation methods of flow standard facility in every regulations were compared and analyzed. Analysis of the two performance parameters of the flow stability within cumulative time and the flow stability between cumulative time. From the two angles of the structure of turbine flow meter itself and the calculation formula of the stability parameter, the selection principle of the stability parameter is determined. The flow stability between cumulative time is selected as the main parameter, and the flow stability within cumulative time as reference. And the results of flow stability test between the method of turbine flow meter and the weighing method were compared. The results show that the method of turbine flow meter can also be an accurate method for testing the flow stability of flow standard facility.
