Evaluation of the Uncertainty of Discharge Coefficient for Differential Pressure Flowmeters for Gases
Differential pressure flowmeter is a commonly used flow measurement instrument,which is widely used in many industrial fields.This paper refers to the calculation method of discharge coefficient in JJG640-2016"Verification Regulation of Differential Pressure Flowmeters",and evaluates the uncertainty of discharge coefficient of differential pressure flowmeter according to JJF 1059.1-2012"Evaluation and Expression of Uncertainty in Measurement".
