摘要
天然气贸易交接计量在天然气贸易中起着重要作用,天然气流量计的准确度直接影响企业的经济效益,然而高压天然气流量计的精确检定仍是一个难题。高压活塞式(High Pressure Piston Plover简称HPPP)气体流量标准装置具有流量稳定、准确度高等特点。研究HPPP法原理并将其应用于天然气检定站场的检定工艺流程和量值传递溯源。
The transferring measurement of natural gas plays an important role in the gas trade. The accuracy of natural gas flow meter directly influences the economic benefits. However, the precise test of the high-pressure gas flow meter is still a problem. HPPP （High Pressure Piston Plover）has many advantages such as stable flow rate and high accuracy. This article discusses the principles of HPPP, the test methods and process used in natural gas test station and the value transferring traceability.
