Study of Flow Calibration Facilities of Master Meter Method with High Accuracy

In this paper,using turbine flowmeter as a master meter of a flow calibration facility,based on the principle of master meter method.Some methods to improve the accuracy of flow calibration facilities of master meter method are analyzed in detail.A method,synchronous pulse counting method,to improve the counting accuracy of facilities is proposed,and the method to obtain precise flowmeter factor is represented.Experimental results show that these methods can obtain a higher accuracy for flow calibration facilities of master meter method.
