摘　　要：近年来,国际上对天然气需求逐年增加,为实现天然气贸易交接的高效和精准,天然气计量手段尤为重要。本文介绍了几种天然气常用流量计,通过对比发现,双腔孔板流量计优势明显。结合孟加拉RMS(Regulation and Metering Station)调压计量站项目的具体工艺条件,根据流量计的计算书,形成以双腔孔板流量计为主要计量仪表的计量系统设计方案。拓展了基于双腔孔板流量计作为天然气贸易计量手段的新思路,为我国“一带一路”发展战略提供了经典案例。In recent years,the international demand for natural gas is increasing year by year.In order to realize the efficient and accurate transfer of natural gas trade,natural gas measurement means are particularly important.This paper introduces several common flowmeters of natural gas.Through comparison,it is found that dual chamber orifice flowmeter has obvious advantages.Combined with the specific technological conditions of Bangladesh RMS(Regulation and Metering Station)project,according to the calculator of flowmeter,the dual chamber orifice flowmeter as the main metering system design scheme.A new idea based on the orifice flowmeter in valve chamber is developed,which provides a classic case for our development strategy of"The Belt and Road".
