摘要:
天然气流量测量是一种连续的测量、一种不可重复的测量、一种因测量结果不正确会引起后续的昂贵代价的测量,需要严密的测量过程控制。核查是实施测量过程控制、确保计量结果准确可靠的重要方法之一,不仅适用于实验室,也适用于工业计量。通过对国内外核查方法应用情况的分析,提出了开发天然气流量计量核查系统的项目,付诸实施后,取得了明显效果。 

Abstract:
As a continuous and unrepeated measurement, natural gas flow measurement maybe cause high cost from incorrect measurement. Hence, it is necessary to be strict in the process control of gas flow measurement. To ensure measurement accurate and reliable, the verification technique is one of the effective methods to implement process control, and it not only be applied in laboratory, but also be widely applied in industrial metrology. The paper analyzes the applications of the verification method at home and abroad,proposes the development project of verification system used in natural gas flow measurement, which is put into practice and achieve remarkable results.
