A method and system of performing multiphase flow measurements. The method includes separating an incoming multiphase flow into a majority liquid component and a majority gas component. The majority liquid component comprises a water component and an oil component. The method further includes determining if the majority liquid component includes entrained gas. If the majority liquid component is substantially free from entrained gas, then the method further includes determining a water-cut of the majority liquid component, determining a density of the majority liquid component using a Coriolis flowmeter, and processing the water-cut and the density of the majority liquid component to determine a density of the oil component.
