Abstract
A method and a device for measuring the qualities of a fluid including at least two liquids, the two liquids having at least one characteristic intrinsic factor relative to microwaves for a given frequency, such as the loss factor. The characteristic of the fluid is measured by a microwave flux for at least two different microwave frequencies, and, with the values of the factors of the intrinsic characteristics of each of the fluids at the two frequencies being known, the respective quantities of the two liquids are determined. The invention applies in particular to measuring the concentrations and flowrates of various phases in a multiphase fluid such as a petroleum effluent having an aqueous phase.
