dc.description.abstract本计量系统以节流装置标准孔板为检测手段 ,采集实时工况参数 :压力、差压、温度 ,根据过热蒸汽流量计量数学模型 ,对流出系数c、流束膨胀系数ε、节流装置开口直径d、节流装置前过热蒸汽的密度 ρ等进行在线实时修正补偿 ,从而达到精确计量过热蒸汽流量的目的
dc.description.abstractIn this metric system, the orifice set is used as the detecting method to collect the real time working parameter i.e. pressure, differential pressure and temperature. In order to measure the flow of the super heated steam accurately, the efflux coefficient c , the efflux expansion coefficient ε , the open diameter d of the orifice set and the density ρ of the super heated in front of the orifice set etc. are corrected and compensated on line by means of the mathematical model for super heated steam flow.
