Detailed description of elliptical gear flowmeter for oil filling machine:

A flowmeter is composed of a measuring box and a pair of elliptical gears installed inside the measuring box, forming a sealed lunar cavity with upper and lower cover plates (not absolutely sealed due to the rotation of the gears) as the unit for calculating the primary displacement. When the measured liquid enters the flowmeter through the pipeline, the pressure difference generated at the inlet and outlet drives a pair of gears to rotate continuously, continuously delivering the liquid measured by the lunar cavity to the outlet. The product of the number of revolutions of the elliptical gear and four times the displacement per time is the total flow rate of the measured liquid
