ABSTRACT:
A microwave system for determining the volume fraction of water in a fluid. In the described application, the fluid is crude oil, and the system is used to determine the volume fraction of water in the crude oil. First and second microwave beams, differing in frequency, reception location, or both, are transmitted through the liquid, and respective absorption losses are calculated. The volume fraction of water is determined according to the absorption losses. Different reception locations are used to detect the passage of a large slug of water.
