Measuring principle
Oval gear meters

As fluid passes through the metering chamber by entering the inlet port, it forces the internal gears to rotate and exits through the outlet port. Each rotation of the gear displaces a given volume of fluid. Controlled clearances between the gears and chamber wall insure minimum leakage. As the gears rotate, a magnet on each end of the gear activates the reedswitch and forward the pulses to the display or to the pulse output.
Applications
Oval gear meters are volumetric meters and are best suited for liquids with a viscosity up to 5.000 mPas. (special models up to 1.000.000 mPas.). Typical applications are mineral oils, hydraulic oils, solvents, brake fluids, coolants, transmission oils, etc.
