天然气能量计量不确定度评定方法OACHSSCD
Method for energy measuring uncertainty of natural gas
在研究ISO15112:2007、GB/T 22723-2008《天然气能量的测定》和其它相关标准的基础上,根据国内某长输管道天然气能量计量的实际情况,对天然气能量计量中的流量测量、温度测量、压力测量、压缩因子测量等参数不确定度进行了研究,提出了不确定度评定计算方法.并使用文中的方法对国内某长输管线上5个有代表性的实验站点的流量测量、温度测量等的不确定度进行了评定,验证了计算方法的正确性和合理性.
Based on the research on "ISO 15112:2007, GB/T 22723-2008 (natural gas energy measurement)" and other related criteria, a concrete research of parameter uncertainty of natural gas in euergy measuring was conducted by taking a West-East Gas Pipeline experimental station as an exauple. A novel calculating method of uncertainty was proposed for the measurement of flow, temperature, pressure, compressibility factor and so on in the energy measurement…查看全部>>
