ABSTRACT:
Volumes of different constitutive phases of a multiphase mixture contained in a vessel are measured after vertical stratification, mainly by comparing by two differential pressure detectors, the pressure generated by three fluid columns, one being totally filled with at least one of the fluids (a liquid phase for example topped by a gas phase), a second one with at least two of the fluids (one liquid phase for example topped by the same gas phase). The vessel can be, for example, an elongated column with a calibrated section arranged vertically and provided with pressure taps at three distinct points of the height thereof which taps communicate with detectors by appropriate fine lines. A processing set combines the pressure measurements in order to obtain the respective volumes of the phases. This method can be used for volume measurements in various vessels; notably in chemical engineering facilities and to conduct tests on porous geographic samples saturated with a multiphase mixture.
