The DFM 100 DK Differential Flow Meter is designed for accurate measurement of diesel fuel consumption in engines with fuel supply and return lines.
Using differential flow measurement, the DFM 100 DK determines actual fuel consumption by measuring the difference between fuel supplied to the engine and fuel returned to the tank.
Ideal for diesel engines, generators, construction machinery, agricultural equipment, commercial vehicles and fleet monitoring systems, it provides reliable fuel-consumption data for operational control, fuel monitoring and telematics applications.

DFM 100DK Differential Flow Meter by Technoton
The DFM 100DK Differential Flow Meter by Technoton is a professional fuel monitoring solution designed for accurate measurement of diesel engine fuel consumption in systems with separate fuel supply and return lines.
Unlike a conventional single-line fuel meter, the DFM 100DK uses differential measurement to determine the amount of fuel actually consumed by the engine. This makes it particularly suitable for generators, trucks, heavy machinery and industrial diesel engines.
Accurate Diesel Fuel Consumption Monitoring
The DFM 100DK Differential Flow Meter measures fuel passing through the engine’s supply and return circuits. By comparing these two fuel flows, the monitoring system can determine actual engine fuel consumption.
Reliable fuel-consumption information can help operators improve operating-cost control, analyse equipment efficiency and identify abnormal fuel usage.
The system is suitable for professional applications including:
- Diesel generators and gensets
- Heavy trucks and commercial vehicles
- Construction machinery
- Agricultural machinery
- Mining equipment
- Stationary diesel engines
- Industrial machinery
- Special-purpose vehicles
- Fleet monitoring systems
- Remote equipment monitoring
How Differential Fuel Measurement Works
Many diesel engines circulate substantially more fuel than they actually consume. Fuel travels from the tank toward the engine injection system, while unused fuel returns to the tank through a separate return line.
The DFM 100DK Differential Flow Meter monitors these supply and return fuel circuits to determine actual engine consumption.
Actual Fuel Consumption = Supply Fuel Flow − Return Fuel Flow
This measurement principle makes differential flow meters particularly useful for diesel engines where conventional single-line measurement is unsuitable.
Generator Fuel Monitoring
The DFM 100DK is an effective solution for monitoring diesel consumption on generators and gensets.
Generator operators can use fuel-consumption information together with engine operating hours, electrical output and load information to evaluate operating efficiency.
When connected to compatible monitoring equipment, fuel-consumption data can also become part of a centralized telemetry or SCADA monitoring system.
This is particularly valuable for organizations operating multiple generators or remote power-generation installations.
Fleet & Vehicle Fuel Monitoring
The DFM 100DK Differential Flow Meter can also form part of a professional fleet telematics system.
Actual fuel-consumption information can be combined with GPS tracking and vehicle operating data, allowing fleet operators to analyse consumption patterns and compare the performance of different vehicles or machines.
This can help organizations:
- Monitor actual diesel consumption
- Analyse fuel efficiency
- Compare vehicle or equipment performance
- Identify abnormal fuel consumption
- Control operating expenses
- Improve fleet management
- Generate fuel-consumption reports
Combine DFM with DUT-E Fuel Level Sensors
For comprehensive fuel monitoring, Technoton DFM flow meters can be combined with DUT-E fuel level sensors.
These technologies perform complementary functions.
DFM: Measures the amount of fuel consumed by the engine.
DUT-E: Measures the quantity and level of fuel inside the tank.
Combining these measurements can provide operators with a more complete picture of fuel consumption, refuelling, tank levels and equipment operation.
Integration with Telematics Systems
The DFM 100DK Differential Flow Meter is designed for professional fuel monitoring applications where consumption information needs to be incorporated into a broader equipment-management system.
Depending on the system configuration and associated equipment, fuel data can be integrated with compatible:
- GPS tracking systems
- Fleet management platforms
- Vehicle telematics
- Generator monitoring systems
- Industrial telemetry
- Remote monitoring platforms
- SCADA systems
This allows fuel information to be analysed together with other important vehicle, engine or machinery operating parameters.
Benefits of the Technoton DFM 100DK
The DFM 100DK provides important advantages for professional diesel fuel monitoring applications:
- Accurate monitoring of actual diesel consumption
- Differential supply and return measurement
- Suitable for diesel engines with return fuel circuits
- Professional fleet fuel monitoring
- Generator fuel-consumption monitoring
- Heavy machinery fuel monitoring
- Remote equipment monitoring
- Telematics system integration
- Improved operating-cost analysis
- Detection of abnormal fuel usage
Professional Solution for Heavy Equipment
The DFM 100DK Differential Flow Meter is particularly suitable for applications where fuel represents a significant part of equipment operating costs.
Construction companies, agricultural operators, transport fleets, generator operators and industrial facilities can use accurate fuel-consumption information to improve operational visibility.
For remote machinery and generators, fuel data can also be transmitted to centralized monitoring platforms, allowing operators to supervise equipment without requiring continuous physical inspection.
Selecting the Correct DFM Fuel Flow Meter
Correct selection and installation are essential for reliable fuel-consumption measurement.
Before selecting a DFM model, several parameters should be considered:
- Diesel engine fuel-system configuration
- Fuel supply flow rate
- Fuel return flow rate
- Engine power
- Fuel type
- Required communication interface
- Monitoring or telematics platform
- Installation environment
The flow meter should always be selected according to the technical characteristics of the specific engine and fuel system.
