DN80 Oval gear flow meter of cast iron KLC-A80.2/Z DN80, for sunflower oil 10-60 m3/h, 2-200 mPa.s

The oval gear flowmeter is composed of a metering unit and a pair of elliptical gears installed in the metering unit, and the upper and lower covers form a crescent-shaped sealed cavity (due to the rotation of the gear, it is not sealed) as the calculation unit of displacement. When the measured fluid enters the flowmeter through the pipeline, the pressure difference generated at the inlet and outlet pushes the gear pair to rotate continuously, and the fluid measured by the crescent-shaped cavity is continuously transported to the outlet. The product of four times the secondary volume is the total measured fluid flow. The elliptical gear generates a torque that causes it to rotate under the influence of the pressure difference △p of the measured medium. Rotor 1 and rotor 2 are alternately driven by one to rotate the other. Each rotor has two magnets as signal generation elements. In the centre of the two axes at the bottom of the cavity is a magnetic signal detection element. Each time the magnet returns to the detection element, the sensor counts a pulse. Each pulse corresponds to a certain amount of media discharge, so the volumetric flow rate of the media removed by each pulse can be obtained.
