METHOD FOR DETECTION OF FLOW PARAMETRES FOR MULTIPHASE MIXTURE OF LIQUID AND GAS Russian patent published in 2010 - IPC G01F1/74 

FIELD: physics.

SUBSTANCE: detectors, which have various dependences of readings simultaneously on at least flow rates of flow components, are placed into measuring hydraulic channel. In order to obtain dependences of detector readings on measured parametres of flow, in process of calibration detector readings are recorded at various combinations of liquid and gas flows, and serial interpolation is carried out. Readings of detectors obtained in process of operation, using calibration dependences, parametres of multiphase mixture flow are defined. In order to detect flows of two mutually insoluble liquids and gas of three-component mixture flow, three detectors are used, dependence of readings of which on flows of liquids and gas differs. In order to detect flows of two mutually insoluble liquids, flow rate of gas and viscosity of flow of three-component mixture, three detectors are used, dependence of readings of which on flow rates of liquids, gas and viscosity differs. In a private case identical detectors are located in serially connected sections of measuring hydraulic channel of various diametre.

EFFECT: invention increases accuracy of multiphase mixture flow characteristics with simultaneous expansion of measured values range.
