Abstract:In view of the problems existing in the calibration of gas flow standard facilities by master method, such as short verification period , complicated removal and installation of master meter, a new method to trace the value of master meter is proposed and by experiments ,the feasibility of this method is verified. Experimental results show that: the meter factor get from the new method is no more than 0.1% different from the traditional method,and the error of the flowmeter calibrated by the flow standard facilities and higher level standard facilities shall not exceed 0.1%.
