FLOW METER Russian patent published in 2017 - IPC G01F1/75 G01F15/14 G01F15/18 

FIELD: measurement equipment.

SUBSTANCE: flow meter for liquids comprises: a measuring case (10) surrounding an impeller (50) mounted therein for rotation, a supply tube (12) and an outlet tube (13); the impeller eccentrically mounted in the outlet tube (13) downstream of a narrow part forming a nozzle (14). The impeller is connected to the transmitting element of the sensor, and the measuring case (10) provides for respective sensor (90) for determining the fluid flow rate through the measuring case (10) based on the number of revolutions of the impeller. The impeller size, corresponding to the outer diameter, is smaller than the nominal inner diameter of the outlet tube (13), which allows the impeller to be installed in the tube (12, 13) made as a single piece.

EFFECT: production of a flow meter having a smaller size and easier to install.
