FIELD: physics, measurement.
SUBSTANCE: measurement electronic device (20) comprises interface (201) for reception of frequency characteristic of flow material and system (203) for processing of data related to interface (201). System (203) for data processing is intended for reception of frequency characteristic from interface (201), breakdown of frequency characteristic at least into frequency component of gas and frequency characteristic of fluid and detection of volume content of gas by frequency characteristic and one or more components from frequency characteristic of gas and frequency component of fluid.
EFFECT: invention provides for higher accuracy of measurements in double-phase flow due to fast detection of frequency by received signals of Coriolis flow metre detectors.
