Abstract
The present invention is directed to a flow meter that obtains the individual flow rates of gas, liquid hydrocarbons, and water in a predominantly gas-containing flowing fluid mixture. The flow meter comprises a water content meter () that provides a signal representing a measure of the water content of said fluid. The flow meter also comprises a double differential pressure generating () and measuring () structure, denoted a DDP-unit (), that provides two measurement signals (A andB) representing two independent values of differential pressure (DP) in said fluid (). In addition to the above, the meter also comprises a signal processing unit () having inputs (A-C) for receiving the measurement signals and the water content signal, and a calculation module () which calculates values representing the volumetric flow rates of said gas, liquid hydrocarbons and water in said fluid.
