基于科氏流量计的凝析天然气计量技术

he on-line metering technology of wet gas flow was briefly introduced; the research works and development of Coriolis meter in two-phase flow metering were reviewed from the points of technology history, theoretical model, field application and signal processing. Three problems were proposed which is closely correlated with the application of Coriolis meter as wet gas meter. A serious of experiments were carried out and some primary experimental results were analyzed, which includes the parameter fluctuant of Coriolis meter, the ways of meter installation and the detection of mixture density and mass flow rate. All of these can be referenced in the research works of accurately metering wet gas flow based on Coriolis meter.
