FIELD: physics.
SUBSTANCE: invention can be used for online observation of industrial processes affecting multiphase fluid media. System for monitoring at least one characteristic property of a multiphase fluid medium comprises at least one pair of electrodes submerged into a multiphase fluid and defining a sample region located between them, signal generating means configured to generate and apply an electrical signal between at least one pair of electrodes, measurement device configured to measure the electrical parameter of the multiphase fluid medium in the sampling region, the measured electrical parameter is forcedly changed in response to the electric current flowing between at least one pair of electrodes, and a processor configured to calculate relative impedance data corresponding to the ratio of the electrical impedance value of at least one phase component of the multiphase fluid medium in the sampling region measured at the first selected frequency value, relative to electric impedance value of at least one other phase component, measured at second selected value of frequency, wherein value or degree of change of data of relative impedance is proportional to at least one characteristic property of at least one phase component of multiphase fluid medium.
EFFECT: invention provides higher efficiency and speed of monitoring composition of multiphase fluid medium.
