DEVICE TO MEASURE PRODUCT YIELD OF OIL AND GAS PRODUCING WELLS Russian patent published in 2013 - IPC E21B47/10 E21B43/34 

FIELD: oil and gas industry.

SUBSTANCE: device comprises an input pipeline, a separator with a float, mechanically connected with a gate valve, a gas pipeline with an installed gate valve, a high-limit gas counter and a two-way pneumatically controlled valve. The valve is equipped with position fixators and a membrane chamber. The liquid pipeline is equipped with a liquid counter and the same valve. The plus cavity of the valve chamber on the gas pipeline is pneumatically connected with the same pipeline - with its cavity between the gate valve and the valve. Valve position fixators are adjusted so that values of pressure drop, which open and close the valve on the gas pipeline, are less than appropriate values of pressure drop, which open and close the valve on the liquid pipeline.

EFFECT: simplified design, expansion of functional capabilities and improved consumer properties.
