Description
Overview
The FM120 is a 1″ mechanical flowmeter for diesel and light oils with a 4-digit resettable batch counter and an 8-digit cumulative total. It measures from 20 to 120 L/min, has an aluminium and plastic body, and is rated to 3.5 bar. The register is driven by the fuel itself, so there are no batteries or cables.
The 8-digit total is useful when you want to reconcile months of issues against deliveries without the count rolling over. Reset the 4-digit batch before each fill to read litres per vehicle. Typical accuracy is around ±1% once calibrated on site. Fit it after a filter to protect the measuring chamber, and mount it where the driver can read the counter without climbing onto the trailer. It is a plain, honest meter that farmhands and drivers understand at a glance.

Where it works
This mechanical flowmeter suits farm tanks in the Free State and Limpopo, bakkie bowsers that stand in the veld for weeks, and municipal depots that want a meter with nothing electronic to fail. If you prefer the meter in the nozzle, see the analogue flowmeter nozzle; for a cheaper turbine option, the FM-TEM turbine flowmeter. More in our fuel flowmeters range.

Questions about this product
Does it need batteries or power?
No. The FM120 is fully mechanical. Fuel passing through drives the counter, so there is nothing to charge, wire or replace. That makes it a good choice for bowsers and remote tanks that stand unused for weeks, and for sites where load-shedding knocks out other electronics.
Can I reset the total?
Only the 4-digit batch counter resets, which you do before each fill. The 8-digit total keeps running and cannot be reset, so you can use it to check fuel issued against fuel delivered over a month or a season. Write down the total reading at each tank delivery.
Will it measure petrol?
No. It is sold for diesel, paraffin and light oils. Petrol requires explosion-proof equipment throughout the system, so do not fit this meter to a petrol line. Contact us if you need advice on dispensing petrol safely on your site.
How much is delivery to Upington?
The meter ships at 1.8 kg, which is in the up-to-30 kg band at R550, Upington included. Our own trucks run from Polokwane and normally arrive within 1 to 3 days. Orders of R20,000 or more including VAT ship free.
