Paper Abstract

A new method for wet gas metering with a long-throat Venturi tube is presented. Correlations between the differential pressures (DP) of the convergence segment and straight segment of the tube and the parameters of gas-liquid two-phase flow are obtained by combining models of orifice and Venturi meters for wet gas metering. A prototype device of the Venturi-based wet gas meter has been designed and constructed. The calibration of the discharge and modification coefficients are accomplished through experiments. Experimental results show that the long-throat Venturi meter can be used to measure the wet gas with a mass quality from 0.06 to 0.412.
