Description
Overview
The FM150 is a 1″ oval gear flowmeter with a mechanical roller counter. Two meshing oval gears move a fixed volume of fluid with each turn, which gives ±0.5% accuracy across 20 to 120 L/min. It suits diesel, paraffin and lubricating oils, and the body is aluminium and plastic.
Positive-displacement measurement is the reason to pick this meter over a turbine. It reads accurately at lower flow and with thicker fluids, so one meter can serve a diesel line one week and an oil drum the next. The counter is mechanical, so nothing needs charging. Supplier pressure data is limited, so check with us if your pump runs above 3 bar. As with any meter, fit a strainer or filter ahead of it, because grit is the main enemy of the gears.

Where it works
Choose this oval gear flowmeter for transport workshops in Gauteng that issue engine oil and diesel, for plant-hire yards that bill customers for fuel, and for farms in the Free State and Mpumalanga that want a tighter count on expensive inputs. For bigger lines step up to the FM900 1.5″ diesel flowmeter, or compare the cheaper FM120 mechanical flowmeter. See all fuel flowmeters.

Delivery and warranty
Kamano delivers with its own trucks from Polokwane to all nine provinces, normally in 1 to 3 days. This item ships at 2.6 kg, which puts it in the up-to-30 kg band at R550. Orders of R20,000 or more (VAT incl.) travel free, so it pays to combine it with a bigger order. Ask us for the warranty terms on this model.
Questions about this product
Why choose oval gear over a turbine meter?
Accuracy and flexibility. An oval gear meter moves a fixed volume with each turn, so it holds ±0.5% across its range and handles thicker oils. A turbine meter is cheaper but reads best with thin fuels at steady flow. If you bill customers or dispense oil, the oval gear meter pays for itself.
Can I use it for engine oil?
Yes. Oval gear meters are well suited to engine and hydraulic oils as well as diesel and paraffin. Very thick gear oils can reduce the maximum flow, so allow for a slower fill in cold weather. It is not suitable for petrol.
How do I calibrate it?
Pump a known volume into a calibrated container at your normal flow rate and compare it with the counter. Adjust using the calibration screw described in the instructions, then recheck. Calibrate separately if you switch between diesel and oil, as viscosity affects the reading slightly.
How much is delivery to Nelspruit?
The meter ships at 2.6 kg, which is in the up-to-30 kg band at R550, Nelspruit (Mbombela) included. Our own trucks leave Polokwane and usually deliver within 1 to 3 days. Orders of R20,000 or more including VAT ship free.
