DFM 100D S7 Differential Fuel Flow Meter by Technoton
The DFM 100D S7 Differential Fuel Flow Meter by Technoton is a professional two-chamber wireless fuel flow meter designed for direct measurement of diesel fuel consumption and engine operating time.
With a measuring range of 10–100 L/h per chamber, Bluetooth 4.1 wireless communication and autonomous battery operation, the DFM 100D S7 Differential Fuel Flow Meter provides an effective solution for vehicles, diesel generators, agricultural equipment, construction machinery and stationary engines.
Differential Fuel Consumption Measurement
The DFM 100D S7 uses two measuring chambers to determine fuel consumption in diesel engine fuel systems with both supply and return fuel lines.
This differential measurement principle enables the system to determine actual engine fuel consumption by monitoring the fuel flow through the supply and return circuits.
The DFM 100D S7 Differential Fuel Flow Meter is therefore particularly suitable for diesel fuel systems where a conventional single-chamber flow meter cannot provide the required consumption measurement.
It can be used for:
- Total fuel consumption monitoring
- Instant fuel consumption measurement
- Engine operating time tracking
- Generator fuel monitoring
- Vehicle fuel monitoring
- Heavy machinery monitoring
- Agricultural equipment monitoring
- Stationary diesel engine monitoring
- Fleet fuel management
- Telematics applications
10–100 L/h Flow Range Per Chamber
The DFM 100D S7 Differential Fuel Flow Meter provides a fuel flow measuring range of:
Flow range: 10–100 L/h per chamber
This makes the unit suitable for a wide variety of diesel engines used in vehicles, generators, construction equipment, agricultural machinery and other commercial or industrial applications.
Wireless Bluetooth 4.1 Communication
One of the major advantages of the Technoton S7 series is wireless data transmission.
The DFM 100D S7 incorporates Bluetooth 4.1 / Bluetooth Low Energy (BLE) technology for wireless transmission of fuel consumption information.
The DFM 100D S7 Differential Fuel Flow Meter operates using Technoton S7 wireless technology, allowing information to be transmitted to compatible:
- GPS and telematics units
- Vehicle tracking systems
- Bluetooth displays
- Smartphones
- Tablets
- Monitoring equipment
The S7 system can transmit information to several compatible receivers, making it particularly useful for modern wireless fuel monitoring installations.
Autonomous Battery Operation
The DFM 100D S7 incorporates an internal battery, eliminating the need for a conventional external electrical power connection during normal operation.
Its low-power wireless architecture is designed for long-term autonomous operation.
The absence of external power and communication cables can also simplify installation and reduce the possibility of accidental cable damage in demanding vehicle and machinery applications.
Typical Applications
The DFM 100D S7 Differential Fuel Flow Meter can be used for fuel consumption monitoring across a wide variety of diesel-powered equipment.
Typical applications include:
- Commercial trucks
- Diesel generator sets
- Construction machinery
- Agricultural machinery
- Tractors
- Heavy equipment
- Special-purpose vehicles
- Stationary diesel engines
- Industrial equipment
- Fleet vehicles
- GPS vehicle tracking systems
- Fuel management systems

The Technoton DFM series can be used with compatible liquid fuels and mineral oils within the manufacturer’s specified viscosity range.
Typical fluids include:
- Diesel fuel
- Heating oil
- Burner oil
- Motor fuel
- Biofuel
- Compatible liquid fuels
- Mineral oils
The specified kinematic viscosity range is 1.5–6.0 mm²/s (cSt).
Always confirm fluid compatibility and installation requirements against the manufacturer’s technical documentation before installation.
