负压法检定气体旋进旋涡量计的计量特性分析

Negative Pressure Method Test Flowmeter Metrological Characteristics Analysis

气体旋进旋涡流量计在工业生产中应用越来越多,主要则是应用在城市能源贸易交接计量中,对其本身的精度要求越来越高。本文就采用负压法检定气体旋进旋涡流量计的测量误差进行分析,以及不确定度的评定做了分析,有利于提高在检测过程中对误差测量的控制。

Gas Swirlmeter application in industrial production more and more, it is mainly used in urban energy custody transfer measurement, the accuracy of their own have become increasingly demanding. In this paper, the use of negative pressure method test gas Swirlmeter measurement error analysis, and to assess the uncertainty of the analysis made, will help improve the control of the measurement error in the detection process.
