摘要：針對天然氣流量計實流標定問題，借鑒Groningen、Bergum和Westerbork的天然氣流量檢測裝置的特點與經驗，采用標準羅茨流量計和標準渦輪流量計作為標準表，以天然氣作為檢定介質，形成標準表法天然氣流量標準裝置。為進一步解決標準流量計的溯源，本文還討論了雷諾內插法的溯源方式連通高低壓溯源鏈的可能性與可靠性，認為當操作條件與檢定條件有差異時可以使用該方法溯源。

Abstract: This paper describes verification methods of natural gas flow meter based on Groningen、Bergum and Westerbork testing apparatus, in which roots flowmeter and turbine flowmeter are used as standard meters, natural gas is used as verification medium. Additionally, we introduces also calibration problem of the natural gas flow meter apparatus. Finall, we discuss Reynolod’s interpolation method and expect this method can be used when eperation condition and verification condition disacord.
Key words: Natural gas flow meter verification apparatus；Natural gas flow；Verification
