Description
Overview
The OGM-50 mechanical flowmeter is a 2″ oval-gear meter with a roller register that counts diesel, kerosene and paraffin with no battery and no wiring. It handles 30 to 300 L/min, so it keeps up with big transfer pumps and tanker offloading while staying completely independent of the grid.
Oval gears trap a fixed volume of fuel on each turn and drive the register directly, giving ±0.5% accuracy and repeatability of 0.03% or better. You get a resettable batch counter for each fill and a cumulative total for stock control. It is a good choice on remote sites, where an electronic display is one more thing to fail in the heat and dust.

Where it works
Mines and quarries in Limpopo and the Northern Cape use mechanical meters on remote diesel tanks, where nobody wants to chase batteries. Farms in the Free State and Mpumalanga fit them on large storage tanks, and contractors run them on bowsers that work far from a power point. Diesel and light oils only, not petrol.

Questions about this product
Does the mechanical OGM-50 need power?
No. The fuel flowing through the oval gears drives the roller register, so it needs no battery or mains. That suits remote tanks and sites that suffer load-shedding.
How accurate is it?
Accuracy is ±0.5% with repeatability of 0.03% or better, which suits stock control and driver accountability. Calibrate on site against a proven measure if you need trade-grade results.
Is it the same size as the OGM-40?
No. The OGM-50 has 2" (DN50) ports and handles 30 to 300 L/min, against 1.5" and 25 to 250 L/min on the OGM-40. At a shipping weight of 6.5 kg it is also heavier, though still in our lowest delivery band.
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 6.5 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.).
