FLOW MEASUREMENT INSERT Russian patent published in 2020 - IPC G01F1/42 G01F1/66 G01D21/02 G01K13/02 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measurement of multiphase flow of oil, gas and water via pipe for ground production, which can be connected to well for oil/gas production. Insert for measuring multi-phase flow for insertion inside pipe comprises first insulating disc arranged upstream, having such size and shape, to form a sealed waterproof seal with inner surface of pipe. Second downstream insulation disc also has such size and shape to form a sealed waterproof seal with inner surface of the pipe. First insulation disc comprises the first hole, and the second insulation disc has the second hole. Lower edge of the first opening is located higher vertically in the first insulation disc than the lower edge of the second hole in the second insulation disc. From the first hole to the second opening the measuring container passes, forming a flow channel, which has a descending slope in case the insert for measuring multiphase flow is in its working orientation.

EFFECT: technical result is creation of easy-to-manufacture and installation of flow meter, which meets safety requirements in operation.
