摘要
伴生气计量仪表目前在油田运用的类型主要有标准孔板节流装置、旋进旋涡气体流量计和气体罗茨流量计三种。在选用转油站湿气计量仪表时，不宜选用容积式计量仪表、标准孔板节流装置和旋进旋涡气体流量计较适合转油站湿气计量，对大口径（ＤＮ＞１５０ｍｍ）伴生气计量装置，以及用于外输伴生气计量交接的仪表，宜选用标准孔板计量装置，在小口径并且不是伴生气计量交接地点的仪表，宜选用旋进旋涡气体流量计一．
There are three kinds of associated gas flowmeter present used in oilfield: standard orifice plate throttling unit, procession vortex gas flowmeter,and gas roots flowmeter. On pump stations choosing wet gas flowmeter is not appropriate. Standard orifice plate throttling unit and procession vortex gas flowmeter are more appropriate wet gas gauging. For associated gas flowmeters which diameter larger than 150mm and handing over meter which uses on out transportation gas gauging, choosing standard orifice plate gauging unit is suitable. For small diameter gauge and not at associated gas handing over site choosing procession vortex gas flowmeter is suitable.
