Patent ID: 11169105

Abstract:
A system for monitoring at least one characteristic property of a multiphase fluid is disclosed. The system comprises at least one pair of electrodes immersed within a multiphase fluid and defining a sample region located therebetween, signal generating means configured to generate and apply an electrical signal across the at least one pair of electrodes, measuring means configured for measuring an electrical parameter of the multiphase fluid in the sample region, the measured electrical parameter being caused to change in response to a flow of electrical current between the at least one pair of electrodes, and a processor configured to calculate relative impedance data corresponding to a ratio of a magnitude of an electrical impedance of at least one phase constituent of the multiphase fluid within the sample region measured at a first selected frequency point relative to a magnitude of an electrical impedance of at least one other phase constituent measured at a second selected frequency point, wherein the value or degree of variation of the relative impedance data is proportional to at least one characteristic property of the at least one phase constituent of the multiphase fluid.
