Oval Gear Transmitter
Models OGT and OGT-SF, 1/2 inch
The Models OGT and OGT-SF electronic lube meters are designed
specifically to dispense motor oils (SAE 5…50), gear oils
(SAE 80…240), automatic transmission fluid, antifreeze (Ethylene
Glycol), brake fluid, windshield wiper fluid, and engine coolant
solutions. Modular design, low cost, lightweight and rugged make
the OGT the best choice for automated dispensing systems.
The transmitter mounted on the meter can be wired to batch
controllers, remote counters and other electronically operated
instruments that can accept pulses from a reed switch, and have
scaling capabilities. The oval gear transmitter is contained in a
plastic housing.
As fluid passes through the metering chamber by entering the inlet
port, the internal gears rotate, forcing the fluid to exit through the
outlet port. Each rotation of the gear displaces a given volume of
fluid. Controlled clearances between the gears and chamber wall
minimize leakage.
As the gears rotate, a magnet on each end of the gear causes the
reed switch to open and close. Contact closures from the switch are
transmitted to a remote batch controller or counter.
1500 psi rating
Leakproof magnetic drive
This transmitter is normally connected to metering systems that
have scaling capabilities and that can accept a reed switch pulse.
Does not require external power
Rugged, corrosion-resistant plastic enclosure
Hermetically sealed reed switch output
Compatible with most flow controllers and counters with
scaling capabilities
Contains only two parts, which reduces maintenance costs
Accuracy to ± 0.75%
Humidity- and moisture-resistant transmitter
Two year limited warranty
Typical applications are automated motor oil batching systems,
antifreeze dispensing systems and other applications that require
totalizing meter flow and monitoring rate of fluid flow passing
through the meter.
NNOTE: The use of meters in applications other than those described
in this material may result in inaccuracy and possible meter
failure. Each meter is designed for use with a specific type
of fluid. Do not use petroleum-based products in a meter
designed for water-based fluids, or water-based fluids in
a meter designed for petroleum-based products. It is also
important that fluids be properly filtered before entering the
meter. Foreign particles will cause inaccuracy or malfunction
of the meter. Warranties are void in the circumstances
described above.
