Experimental Investigation of the Wet Gas Measurement Based on Triple Differential Pressures Method

摘要

In order to meter the wet gas without separation online, a novel measurement device composed of a long throat Venturi tube and a V-cone is proposed and a new metering method based on triple differential pressures. In this method, the ratios of the differential pressures are vital parameters used to establish the measurement correlations. The comparison of these correlations is also presented. In laboratory test, the measurement accuracy of the gas and liquid are 2.13% and 6.68% respectively.
