<b>Abstract.</b> The accurate flow rate measurement of multi-phase flows is an important task in petroleum and petrochemical industry. Unlike the measurement of single phase flows using differential pressure meters, the multi-phase flow behavior poses difficulties for the accurate measurement. This work examines the characteristics of the multi-phase flow in differential pressure flow meters such as Venturi meters. For this purpose the Two-Fluid model, based on an Eulerian - Eulerian approach for the multi-phase mixture, will be used and it will be focused on the study of dispersed flows. In differential pressure-type flow meters, the accuracy depends strongly on the knowledge of the flow behavior, fundamentally about the relation between differential pressure and mean velocity of the flow. For multi-phase flow these relations are not fully known, and there are several new variables affecting the flow, like void fraction, relative velocity between phases (slip velocity), interfacial momentum transfer, etc.. Preliminary results obtained using the two fluid model are compared with experimental values of velocities distributions and differential pressure across the Venturi.
