摘要：An apparatus for measuring a multiphase fluid stream which flows in a pipe ()comprising: a measuring unit (), coaxial to the pipe, consisting of an isokinetic samplingdevice () suitably configured for allowing the equidistribution of the flow at the inlet in n
channels () having an area A, of which m are sampling channels and a flow restriction ()both equipped with differential pressure measuring means (), a phase separator (),connected to the sampling device, measurers and regulation means downstream of saidseparator. A method in accordance with said apparatus which comprises: the isokineticsampling of a portion q of the multiphase flow Q at the inlet, measuring the flow-rates ofthe liquid qL and gas qG of the portion sampled and calculating the liquid and gas flow-rates (QL and Q) from the sampling sections according to the equations QG=n/tn qG andQL=n/m qL. The method provides isokinetic sampling for portions of flow removedranging from 5% to 20%.
