METHOD OF FAST DETERMINATION OF LIQUID PHASE VOLUME CONTENT IN GAS-LIQUID FLOW AND DEVICE TO THIS END Russian patent published in 2012 - IPC G01F1/74 

FIELD: machine building.

SUBSTANCE: proposed method consists in isokinetic sampling of gas pipeline, using filter to separate liquid phase and measuring said phase volume fraction at fixed volume flow rate of gas-liquid mix. Note here that a-priori known liquid density (ρ_l) is used. Then, measured is density of gas flow not containing liquid phase (ρ_g) while volume content of liquid phase in has-liquid flow (volume content of liquid η) is defined from relation: Proposed device comprises isokinetic sampler, filter to separate liquid phase, volume flow rate meter and rotameter calibrated in units of density at constant flow rate. Aforesaid filter is made up of electric filter of elongated volume filled with thin-wall metal structure, cellular in crosswise direction and elongated in lengthwise directions. Filamentary electrode is located at the center of every cell whereto high voltage is fed.

EFFECT: continuous measurement and calculation of important parameter, actual density, ρ_c, possibility of use integrated with two-phase SHF-flow rate meters.
