FIELD: oil and gas production.
SUBSTANCE: liquid-gas mixture component-wise flow metre comprises a variable pressure drop flow metre in the form of a built-in fluid oscillator (3) with a power nozzle (5) and a jet collision chamber, a differential pressure pickup (8) on the fluid oscillator. In side walls (13) of the jet collision chamber, there is a measuring circuit (2) of a moisture metre so that the walls from both sides of the chamber are simultaneously regarded as a resonant circuit of the moisture metre. The moisture metre capacity is limited by the power nozzle (5) and a hydraulic outlet (6) of the fluid oscillator. The moisture metre and flow metre - moisture metre (3) are connected to a calculator (4).
EFFECT: higher accuracy of measuring volume flow rate of gas, condensate and water.
