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 (7) that provides a signal representing a measure of the water content of said fluid. The flow meter also comprises a double differential pressure generating (3) and measuring (4) structure, denoted a DDP-unit (2), that provides two measurement signals (6A and 6B) representing two independent values of differential pressure (DP) in said fluid (1). In addition to the above, the meter also comprises a signal processing unit (8) having inputs (9A-C) for receiving the measurement signals and the water content signal, and a calculation module (10) which calculates values representing the volumetric flow rates of said gas, liquid hydrocarbons and water in said fluid.
