浅谈天然气流量量值溯源

分析了天然气流量量值溯源所具有的特殊性，介绍了天然气流量量值溯源的重要组成部分，其中对国际上具有代表性的MT法、HPPP法和PVTt法天然气流量原级标准装置的工作原理、不确定度范围及应用作了重点介绍。指出，增加核查标准装置和积极参加天然气量值国际比对活动对提高我国天然气流量量值溯源工作的重要意义。

Discussions on the Quantity Traceability of Natural Gas Flow Rate

Based on the analysis of the particularity in the quantity traceability of natural flow rate, an introduction focuses on the key components of the quantity traceability of natural flow rate, especially on the working principle, the uncertainty range and the appli- cation of the MT, HPPP and PVTt methods about the primary standard equipment of natural gas flow rate. At last, some suggestions are put forward in order to increase the checking standard equipment, to participate in the international contrastive activities about natural gas quantity actively, and to improve the quantity traceability of natural gas flow rate in our country.
