Aluminum alloy Oval Gear Flow Meter with pulse /4-20mA
Gear flow meter is a kind of flow meter for measuring volume flow rate with high precision. With the flowof the medium, the gears mesh and rotate; under the action of fluid flow, the differential pressure is formed at both ends of the instrument's inlet and outlet, and no power supply is required; a pair of gears rotate freely and the cavity between the gears is filled with liquid; the liquid is discharged with the rotation, and the flow rate of the liquid flowing through the instrument can be known by measuring the number of revolutions of the gears.
