摘要
提出宽量程膜式燃气表校准过程的修正系数的概念,对在膜式燃气表修正系数测量过程中影响测量结果的不确定因素进行了逐项分析评定及合成。采用JJF 1059.1—2012《测量不确定度评定与表示》规定的方法对测量结果进行报告。
The concept of correction coefficient in the calibration process of wide-range diaphragm gas meter is put forward,and the uncertain factors affecting the measurement results in the measurement process of correction coefficient of diaphragm gas meter are analyzed,evaluated and synthesized item by item.The method stipulated in Evaluation and Expression of Uncertainty in Measurement(JJF 1059.1-2012)is used to report the measurement results.
