THE ESTABLISHMENT OF THE HIGH-PRESSURE GAS QUANTITY TRACEABILITY SYSTEM

摘要：

　　This article introduces the quantity traceability system of high-pressure gas flow standard devices that Nanjing branch and Guangzhou branch of national station of petroleum and natural gas flow have established.The system,including the original grade standard devices,secondary standard devices,working standard devices and working measuring instruments,calibrates and verificates high-pressure natural gas as the medium.In this paper,the working principle,the composition,the analysis and evaluatation of uncertainty in measurement,that belongs to secondary standard devices and working standard devices of Guangzhou branch,have been described in detail.
