Abstract
A device and method for determining the proportion of the phases of a multiphase fluid is disclosed. The device includes microwave emission and reception devices which are suited to the composition variation of the multiphase fluid, a processor and control for determining directly, from measurements of amplitude and phase shift of a beam crossing the multiphase medium and a rate of occupation of liquid phase and/or a gas phase for a given section of the pipe. The flow rate of each of the phases is determined.
