Abstract　Th is paper int roduces a new in2line technique fo r metering the mult iphase flow of o ilöw aterög as. It in2 tegratedly ut ilizes the state2of2art measuring and cont ro l techniques of mult iphase flow condit ioning, cro ss co rre2 lat ion flow measuring, dual gamma fract ion measuring,mult iphase flow analog computat ion, computer cont ro l and
communicat ion technique etc. to meter in2line the mult iphase flow. It has great ly imp roved on the adap tability of flow regimes,measuring range and measuring accuracy etc. Based on these techniques the mult iphase metering p roduct s have been successfully tested and evaluated by the domest ic and overseas autho ritat ive o rganizat ions. The main specificat ions have come up to and surpassed the levels of the same type p roduct smanufactured by fo r2 eign companies.
