METHOD FOR SIMULTANEOUS DETERMINATION OF FLOW RATES AND CONCENTRATIONS OF COMPONENTS OF MULTIPHASE MIXTURE WITH SELF-CHECK FUNCTION (VERSIONS), AND INTELLIGENT MEASUREMENT SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC G01F1/74 

FIELD: measurement equipment.

SUBSTANCE: invention relates to control and measurement equipment and can be used for determination of flow rate values of a multiphase flow without any preliminary separation, for example for measurement of flow rate of oil wells. The proposed intelligent measurement system includes devices for metrological self-check, namely two velocity sensors and two sensors of acoustic specific conductivity, which are located in the first and second pipe sections respectively, for which alignment of fields of the measured values is provided. For that purpose, the above two pipe sections are connected in series and have a similar cross section. There are two versions of the method's implementation. According to the first version, readings of the above sensors are compared to provide metrological diagnostic self-check of the system. The second version of performance of metrological diagnostic self-check of the system involves calculation of flow rates of two liquid and gas phases for each of the pipe sections and their comparison. The above described system implements any of the above methods or simultaneously both of those methods.

EFFECT: proposed invention provides a possibility of metrological self-check of an intelligent measurement system.
