General information

The model LM OGT-HF High Flow meter is designed to handle flow rates up to 115 l/m. The meter is designed specifically to dispense motor oils (S.A.E. 5-50), gear oils (S.A.E. 80-240), automatic transmission fluid, antifreeze (Ethylene Glycol), and engine coolant. Modular design, compact foot print, and rugged design make the LM OGT-HF the best choice for automated dispensing systems.

Measuring principle

Oval gear meters

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.
