天然气管道标准孔板流量计计量误差的分析

Error analyze for measurement of natural gas flow by standard orifice meter

结合国家石油天然气行业2004最新实行标准SY/T 6143-2004对长输天然气管道供气单位与用户双方气量交接中的孔板流量计计量误差进行了一些分析;其次,通过一定量的计算,分析了孔板流量计计量中各参数和变量对计量误差的影响,并对误差大小做了一个粗略的估算;最后,结合所做的误差分析,从个人角度对孔板计量装置的合理设置谈几点粗浅的认识,供同行业参考,探讨。

This text combines the national petroleum natural gas profession 2004 practice standard SY/T6143 - 2004 rightnesseses to lose the natural gas piping at grow to be provided for the spirit unit and the customer both parties＇tolerance to hand over to connect lately medium of the bore plank flowmeter calculated an error margin to carry on some analysis;Pass one calculation of the fixed amount secondly, analyze the bore plank flowmeter to calculate to win each parameter and change quantity to the influence that calculates an error margin, and did a to the error margin size to estimate roughly; End, combine the error margin do analysis, calculate the reasonable constitution of the device to talk to the bore plank from personal angle what time superficial understanding, provide to go together the industry reference, study.
