Description
Overview
The OGM-40 mechanical flowmeter is a 1.5″ oval-gear meter that counts diesel, biodiesel, kerosene and paraffin through a roller register, with no battery and no electrics. If your bowser, tank stand or fuel bay is out in the veld and load-shedding is a fact of life, this is the meter that keeps counting.
Two rotating oval gears trap a fixed volume of fuel on every turn, and the register shows it on a resettable batch counter and a cumulative total. Accuracy is ±0.5% with repeatability of 0.03% or better, which is good enough for stock control and for checking drivers against the dip. For trade use, calibrate it on site against a proven measure.

Key features
- Mechanical roller register, no battery to replace
- Resettable batch total and non-resettable cumulative total
- Positive displacement oval gears, ±0.5% accuracy
- 25 to 250 L/min through 1.5″ (DN40) connections

Where it works
On Limpopo and Free State farms the OGM-40 sits on the delivery line from the main tank to the tractor and bakkie bay. Contractors use it on diesel trailers to account for fuel by machine, and mine workshops and transport depots in Mpumalanga and Gauteng fit it where a simple, tough counter beats electronics. It is for diesel, kerosene and light oils only, not petrol.

Questions about this product
How accurate is the OGM-40 mechanical flowmeter?
Accuracy is ±0.5% with repeatability of 0.03% or better. That suits stock control and driver accountability. For trade or custody transfer, calibrate it on site against a proven measure, because installation and fluid viscosity shift the reading slightly.
Does this meter need a battery or power?
No. The mechanical roller register is driven by the fuel flowing through the oval gears, so there is nothing to charge or replace. That makes it a good fit for remote farm tanks and sites hit by load-shedding.
Can I use it for petrol?
No. This is a standard meter for diesel, biodiesel, kerosene, paraffin and light non-corrosive oils. For petrol you need an explosion-proof unit, so contact us and we will advise.
Do you deliver to a farm or mine outside the big centres?
Yes. We deliver with our own trucks from Polokwane to all nine provinces in 1 to 3 days, including farms and mine sites. At a shipping weight of 3.8 kg this meter falls in the up to 30 kg band, so delivery is R550, and free on orders of R20,000 or more (VAT incl.).
