FIELD: oil and gas industry.

SUBSTANCE: device consists of a vertical cylindrical vessel, input and output liquid lines made in the form of siphon pipe, a gas line, gas-phase pressure and temperature gauges, a computing element. Volume displacement metre and a stop valve are installed in the common line, one by another, before the line entry into the collecting reservoir, at that the gas line and the output liquid line connected by downward siphon pipe are communicated with hydraulic lock. Pressure and temperature gauges are installed in the gas line; the stop valve, the volume displacement metre and the computing element are interconnected through a pulse distributer for measurement of the working medium. The stop valve is a bypass valve of step-by-step action with magnetic locking, discharge and control of positions - open and closed.

EFFECT: improving accuracy and quality of well gauging.
