METHOD FOR DETERMINING AMOUNT OF WATER AND OIL IN WATER-OIL EMULSION Russian patent published in 2006 - IPC G01N22/04 

FIELD: oil industry, possible use when determining amount of water and oil in water-oil emulsion.

SUBSTANCE: when determining amount of water and oil in water-oil emulsion, constant electric current with value, providing synchronization of wave resistance of source-receiver and wave duct, is sent from source-receiver via wave duct, made in form of two-wire isolated line with Schottky diode between lines. Simultaneously from source-receiver along wave duct high-frequency electric current is sent, time of expansion of high-frequency current along wave guide is measured. Wave guide of fixed length is used and it is positioned in moving water-oil emulsion. From source-receiver along wave duct simultaneously sent is high-frequency electric current and direct electric current, greater, than current of synchronization of wave resistance of source-receiver and wave guide. Resulting current is measured. Time and speed of current expansion along wave guide are measured and amounts of water and oil in oil-water emulsion are computed.

EFFECT: increased efficiency.
