Abstract:
1. Flow meter capable of measuring the individual flow rates of gas, liquid hydrocarbons, and water in a predominantly gas-containing flowing fluid mixture comprising: a water content meter comprising a microwave resonator for providing a signal representing a measure of the water content of said fluid mixture based on a measure of dielectric permittivity, a double differential pressure generating unit DDP-unit for measuring two differential pressures in said fluid and for providing therefrom two measurement signals representing two independent values of differential pressure in said fluid mixture, a signal processing unit having inputs capable of receiving said two measurement signals and said water content signal, and a calculation module for calculating values representing the volumetric flow rates of said gas, liquid hydrocarbons and water in said fluid mixture, and wherein said DDP-unit and said microwave resonator are combined in a common structure.
