Fuel Flow Measurement Redefined: The DFM Marine Flow Meter for Heavy Machinery
Discover the unparalleled precision of the DFM Marine fuel flow meter, tailored explicitly for heavy machinery. Whether it’s marine vessels, trains, mining equipment, or stationary engines like diesel generators. This model delivers fuel consumption measurement with accurate readings, revolutionising how you view fuel consumption.
Why the DFM Marine Flow Meter Stands Out:
- Versatility: It’s compatible with a wide range of liquids – diesel fuel, heating oil, burner oil, biofuel, and other fuels boasting a kinematic viscosity of 1.5-6mm²/S.
- Material Excellence: At its core, the measuring chamber is crafted from brass, ensuring corrosion resistance and prolonged durability.
- Customisation: Tailor your DFM Marine to fit your needs. Opt between the duralumin or brass bodies and select your preferred fuel line connection, be it threaded or flange.
How it Operates: Positioned past the fine filter in the fuel line, the DFM Marine operates as a direct volumetric fuel measurement device, housing a unique ring-type measuring chamber. As the fuel pressure drives through the flow meter inlet, the ring traverses along the chamber’s inner surface, pushing the fluid out systematically. For each complete ring rotation, a volume equivalent to the chamber’s capacity is pushed out. Volume is automatically calculated by the flow meter’s electronic unit.
Integrate your results seamlessly with Fuel Monitoring, GPS Fleet, or Telematics Monitoring Systems. This synergy provides real-time data insights and live t p conditions (t p = temperature and pressure). Therefore, making it a pivotal tool for informed decision-making.
Key Insights Delivered:
- Fuel Consumption Metrics: Gain insights into instant fuel consumption rates, hourly fuel consumption, overall consumption, and consumption during different engine modes.
- Operational Analysis: Track the total operational hours, differentiating between modes like “Idling”, “Overload”, and “Optimal”. Plus, reset counters as needed.
- Special Features: In addition, dive deep with insights into “Tampering” and “Interference” modes, current engine operation status based on consumption, fuel temperature, battery charge, and more.
- Diagnostics Function: Assess the flow meter’s performance, adapt settings to fuel system parameters, and access diagnostic codes and event logs for a holistic view.
Finally, enhance your experience further with the Service S6 DFM Software for PCs. Enabling you to tweak settings for units of measurement, operational mode boundaries, and temperature correction coefficients.
DFM Marine Models
The DFM 2000 allows measurement of consumption from 40 to 2,000 litres per hour. See below other model options.

- *Minimum threshold flow rate value when the meter starts operating. The value is indicated for reference only. Therefore, accuracy is not standardised for operation on the starting flow rate.
- **In differential/summarisation measurement mode, in accuracy is not higher than ±1.0% (depending on the proportion of fuel consumption in the chamber of each flow meter used)
- *** If fuel consumption in the range from Qmin to e-Qmin, the allowed inaccuracy is not more than ±1.0% . Therefore, for differential/summarisation fuel consumption modes – not more than ±2.0%
Power Supply
- Stand-alone power supply (DFM Marine C models) DFM Marine is powered from the built-in lithium-silicon battery. Estimated DFM Marine operation time until full battery discharge is not less than 36 months.
- Combined power supply (DFM Marine CK/CCAN models) — DFM Marine is powered from the external power source or built-in battery (in case external power is off). Power supply is switched to stand-alone mode in case of low level of external power supply (less than 8 V). Estimated DFM Marine operation time in this mode is not less than 36 months.
