Abstract: Wet gas is a s ub - set of gas - liquid two - phase flow, which widely exists in industrial processes, especially in the natural gas industry. The accurate flow rate measurement of wet gas is of great importance. Differential pressure (DP) flow meters, such as orifice plate flo w meters, Venturi flow meters and V - Cone flow meters, are the most commonly used meters in wet gas flows due to their low capital expenditure and robust performance. The mostly common approach to realize two - parameter measurement is the so - called dual - DP met hod, which can be subdivided into dual - throttle - device method and single - throttle - device method. The metering principles of dual - DP method is on the basis of over - reading correlations. The gas and liquid flow rates are obtained by solving the combined cor relations. The drawback of such method is error propagation, which results in the prediction error of the liquid phase flow rate being much larger than that of the gas phase. Besides, the method may fail in particular cases (the equations have no solution) . The other alternative approach is to utilize the fluctuation of DP signals. However, the prediction accuracy is not satisfied.
