INDIVIDUAL LIQUID FUEL METER Russian patent published in 2021 - IPC C01F1/00 

FIELD: instrument engineering.

SUBSTANCE: invention relates to instrument-making, particularly, to measurement of fuel consumption in internal combustion engines, and can be used for control during filling with liquid fuel. Individual fuel liquid meter comprises a collection cylindrical housing consisting of an inlet branch pipe connected through a conical adapter with a magnetic permeable measuring cylinder with an internal diameter D₁, inside which there is a piston with diameter D₂ smaller than D₁, the end of which facing the inlet branch pipe has the shape of a truncated cone with a diameter equal to the inner diameter of the inlet branch pipe, and opposite end along periphery is equipped with four U-shaped staples made from magnetically impermeable material and located in circumferential direction with 90° interval, in one of which a magnet is inserted, and in the other three – retainers adjacent to inner surface of measuring cylinder and to spring, diameter of which is slightly less than D₁, resting against measuring ring end ring, connected to outlet pipe, wherein the annular gap between the measuring cylinder and the piston forms a living cross-section equal to or greater than the live cross-section of the inlet branch pipe, to the outer side of the measuring cylinder, to which a magnet adjoins, an electronic unit is pressed, in the bottom of which there is a row of magnetically sensitive elements, a temperature sensor is mounted in the wall of the inlet branch pipe, which are connected to a signal converter, a timer, an accumulator placed in the unit and a display in the cover of the above unit.

EFFECT: technical result is higher measurement accuracy and higher economic efficiency of individual liquid fuel meter.
