体积管检定容积式流量计的测量不确定度的分析与表示

Analysis and Indication of the Uncertainty of Measurement of Pipe- type Testing Volume Flowmeter

根据JJG1059-1999提供的技术指导,结合JJG667-97《容积式流量计检定规程》,以体积管检定流量计为例,对如何计算不确定度作了探讨,并设计了在检定证书中不确定度的规范表示格式。

Based on the technical guide provided in jjG1059-1999 and “Testing Procedure of Volume Flowmeter”JJG667-97, how to calculate the uncertainty of the pipe-type testing flowmeter is discussed, and the standard format to indicate the uncertainty in the test certificate is designed.
