Operational principles
Measurement of elliptical gear flowmeter is composed of a casing and a pair of gearrotor and the upper and lower cover plate, a known volume of cavity between them as measure unit flowmeter. The slight pressure on the inlet of the gear rotor differential drive rotation, and will continue to import liquid through the cavity measurement to export. According to the rotation frequency rotor to counter (two meter), indicating the flow.
