膜式燃气表测量结果不确定度评定

Evaluation of Uncertainty of Measurement Results of Membrane Gas Meter

膜式燃气表是计量燃气消耗量的常用计量器具,其量值是否准确直接保证贸易结算的公平合理。通过对测量结果进行的不确定度评定,从而对检测设备及检测样品做出适当的评价,以验证其是否符合相关标准的规定。本文以漯河市质量技术监督检验测试中心燃气表检定计量标准建立时取得的数据为基础,依据2005年我国发布的膜式燃气表检定规程,在规定的标准环境条件下对膜式燃气表测量结果的不确定度进行分析和评定。

Membrane type gas meter is a commonly used measuring instrument which calculates the consumption offuel gas .The accuracy of the value of a quantity will ensure a fair trade settlement. Through the uncertainty evalua？tion to the measured results to make an appropriate evaluation to the testing equipment and the testing samples to testwhether they accord with the provisions of relevant standards.This text is based on the data when the gas meter cali？bration and measurement standards of quality and technical supervision, inspection and testing center in Luohe Cityare set up.According to the membrane type gas table verification regulation which is published in China in 2005, toanalyse and evaluate the uncertainty of membrane type gas table of measurement results under the provisions of thestandard environmental conditions.
