摘要
论述在中压天然气流量计实流标定中,调压及流量点调节引起检定用天然气各参数变化对测量准确度的影响。并讨论了中压天然气流量计实流标定中天然气压力和温度的控制调节方法,保证检定用天然气各参数的波动符合检定规程的要求。
In this paper, we discussed the influence of changes in related parameters upon the measurement accuracy, under natural gas pressure regulation and traffic point regulation. The control method of gas pressure and temperature was discussed, to meet the requirement of the verification regulation.
