DEVICE TO MEASURE COMPOSITION OF MULTI-PHASE MIXTURE FLOW Russian patent published in 2015 - IPC G01F1/74 

FIELD: measurement equipment.

SUBSTANCE: device to measure composition of a multi-phase mixture flow comprises a measurement tube (1), forming a pipeline for the multi-phase mixture flow, a radiation facility (2) to radiate the multi-phase mix in the measurement tube (1) with electromagnetic radiation, a detection facility (3) to detect radiation of the radiation facility (2), which passes via the multi-phase mix in the measurement tube (1), An analysis facility (5) to determine composition of the multi-phase mixture on the basis of detected radiation and calibration data of at least one liquid phase and at least one gaseous phase, at the same time a calibration vessel (4) is placed near the measurement tube (1) so that the radiation facility (2) may radiate the calibration vessel (4), and the detection facility (3) may detect radiation of the radiation facility (2), stretching via the calibration vessel (4); the calibration vessel (4) may connect to the measurement tube (1) so that the calibration vessel (4) is filled with the multi-phase mixture or appropriate phases of the multi-phase mixture from the measurement tube (1); there is a data collection facility (6) to produce calibration data from radiation detected by the detection facility (3), which passes via the calibration vessel (4), when the calibration vessel (4) is filled with a multi-phase mixture or appropriate phases of the multi-phase mixture from the measurement tube (1).

EFFECT: provision of the possibility of self-calibration with measurement of composition of a multi-phase mixture flow.
