Description
Overview
The M-50 (BT-M50) is a 2 inch diesel flow meter of the positive displacement type, reading from 38 to 550 L/min on a mechanical totalising register. It shares its cast aluminium body with the M-40 but takes 2″ pipework, which suits most small and medium road tankers.
Calibrated on site it holds about ±0.5%, and the body is rated to 10.5 bar. The register takes a ticket printer for dockets or a pulser for a fuel management system, so it can grow with your operation.
Because the same body serves the M-40 and M-50, spares such as gear plates and registers are shared, which keeps a mixed fleet simple to maintain. Plan for a strainer and air eliminator ahead of the meter, isolation valves on both sides and a proper bracket, since at about 24 kg it should not hang on the hose.
Key features
- 2″ (DN50) bore, 38-550 L/min
- Positive displacement measuring element
- Cast aluminium body, 10.5 bar maximum
- Mechanical totalising register with reset
- Ticket printer and pulser options
Where it works
This 2 inch diesel flow meter is the common choice on road tankers delivering to farms in the Free State grain belt, on depot loading points that fill bowsers and smaller tankers, and at mines and municipalities receiving 2″ deliveries. It handles a wide flow band, so the same meter works on gravity drops and pumped deliveries. For more flow, the M-80 3″ bulk flowmeter takes over, and the M-100 4″ bulk flowmeter tops the range.

Questions about this product
What is the difference between the M-50 and the M-50 digital?
They share the same 2" measuring body and 38-550 L/min range. The standard M-50 has a mechanical register that needs no power, while the digital version carries an electronic register running on 220V AC. Choose mechanical for tankers and remote sites, and digital where you have mains power and want an electronic readout.
Can I add a ticket printer to the M-50 later?
Yes. Swap the plain register for our mechanical register with ticket printer for M-40, M-50 and M-80 meters. It bolts onto the same body with its own gear plate, and uses the standard M-series ticket booklets. Many tanker owners start with the plain register and add the printer when customers ask for dockets.
Do you deliver to Bloemfontein, and what does it cost?
Yes. Our own trucks run from Polokwane to all nine provinces, normally in 1 to 3 days, and Bloemfontein is on the route. The M-50 meter weighs about 35 kg packed, so on its own it falls in the 30 to 60 kg band (R950). Because the price is above R20,000, delivery on this order is free.
