湿式气体流量计是一种具有独特误差特性的容积式流量计,其计量校准需遵守特定的技术规则,测试人员除具备流量计量基本素质外,还应熟悉湿式气体流量计的工作原理、基本结构和应用要求。需要注意的是,JJF1357-2012《湿式气体流量计校准规范》主要适用于实验室条件下,湿式表作为标准装置时的校准依据;而作为贸易结算的计量器具,其检定依据宜参照JJG633-2005《气体容积式流量计》检定规程。
Wet gas flow meter is a kind of positive displacement flowmeter with unique error characteristics. Its measurement and calibration must comply with specific technical rules. Besides the basic quality of flow measurement, testers should also be familiar with the working principle of wet gas flowmeter. The basic structure And application requirements. It should be noted that, JJF1357-2012 “wet gas flowmeter calibration specification” is mainly applicable to laboratory conditions, the wet meter as a standard device calibration basis; and as a trade settlement measuring instruments, the test basis should refer to JJG633-2005 “Gas volumetric flowmeter” test procedures.
