| 摘 要： | 基于质量-时间法高压天然气流量标准装置的天然气原级计量中的附加管容对计量精度有不可忽略的影响,通过研究附加管容的容积不确定度、气体的密度不确定度、时间不确定度等影响因素,给出了附加管容质量不确定度的计算方法,为降低由附加管容引起的原级计量装置的不确定度给出理论依据。

| Abstract: | The influence of the additional pipeline capacity is not neglectable in the high pressure natural gas flow rate standard device based on mass-time method.Through the study of volume uncertainty,gas density uncertainty and time uncertainty, the calculation method of mass uncertainty in additional pipelines is given as well as the theoretical basis for reducing the uncer-tainty. |
