Pressure drop and void fraction are important hydro-dynamic aspects for wet gas metering. Among differential pressure drop meters, Venturi meters are the most favoured devices for measuring unprocessed wet gas flows. However, Venturi meters are based on dry gas metering concepts, and various correlation factors have to be applied to the readings, Because the correction factors are flow-regime-dependent and only valid within specified operating flow conditions (preferably homogeneous or quasi-homogeneous flows), preconditioning or mixing devices are required. Electrical capacitance tomography (ECT) has been applied to measure wet gas separation processes. A combination of Venturi and ECT present the strengths of both principles and overcome the respective disadvantages. The combination also gives a possibility for wet gas pressure gradient calculation using void fraction measurement from ECT.
