FIELD: oil industry.
SUBSTANCE: method for measuring the flow rate of a gas-liquid flow relates to the field of measuring the flow rate of multicomponent gas-liquid flows and can be used in the oil industry. The technical result is achieved in that, according to the method, a flow is passed through a flowing longitudinal slit-shaped body with an inlet, a thermal charge pulse is supplied at the input, measured components charged at the same time to different temperatures are advanced with a flow through the body, the flow rate is measured by the time of passage through the body of a thermal charge, using a thermal imager, a thermogram of a heat mark moving with the flow, the mass fractions of the components and the total consumption are calculated.
EFFECT: invention provides a simplified measurement of the flow rate of a multicomponent gas-liquid flow using a single simple thermal parameter for identifying the measured component of a gas-liquid flow.
