摘要
差压式流量计是一种常用的流量测量仪表,广泛应用于多种工业领域.本文参照JJG 640-2016《差压式流量计检定规程》中流出系数的计算方法,依据JJF 1059.1-2012《测量不确定度评定与表示》,对差压式流量计的流出系数进行不确定度评定.
Abstract
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".
