Eurosens Dominator Fuel Level Sensors
Accurate fuel level and volume monitoring — wired or Bluetooth. For vehicles, machinery, fuel tanks and stationary installations.
Wired or wireless?
Same measurement core. Choose the connection that fits your installation.
Wired Dominator
For permanent installations with direct connection to a GPS/GLONASS tracker, display or control system.
Dominator BT
Autonomous fuel level sensor with Bluetooth Low Energy. No signal cable routing between the sensor and receiver.
* Direct line of sight — final figure to be confirmed against the current datasheet for the relevant modification.
Built to work, not just to measure
Six operational advantages that matter on the road and on the workshop bench.
Modular design
The measuring part can be shortened to fit shallow tanks or extended with standard electrode modules for deep ones — one platform, any tank depth.
Bayonet mounting
Rotate and lock. The sensor can be removed for service or calibration check without touching the tank fitting.
Fuel volume inside the sensor
The tank calibration table can be stored inside the sensor, so the tracker receives fuel volume in liters directly.
Temperature compensation
Built-in compensation keeps the reading accurate across seasonal and climate extremes.
Fuel theft detection
Sudden-drop detection is available on wired modifications where the function and output are confirmed by documentation.
Built for vehicles
Designed for the vibration, moisture and electrical environment of commercial vehicles and mobile machinery.
Which Dominator do I need?

Eurosens Dominator Wired
One sensor platform for virtually any common telematics interface.
* Electrical parameters and the interface list are to be finally confirmed against the current datasheet for each modification before publishing.
No sensor cable. No complicated cable routing.
Eurosens Dominator BT — autonomous wireless fuel level monitoring over Bluetooth Low Energy.
* Direct line of sight. ** Designed battery operating time, to be confirmed against the current datasheet — not to be confused with the product warranty period.

Where wireless makes sense
Trailer
No cable between tractor and trailer.
Hard-to-reach tank
No long sensor cable routing.
Stationary tank
Wireless transmission to a nearby receiver.
High cable damage risk
No external sensor signal cable to cut or damage.
What you actually monitor
Dominator turns a raw capacitance reading into the numbers your fleet actually needs.
Example fuel level trend with a refuel and a fuel drain event
Where Dominator is installed
From box to reading in four steps
Measure tank depth
Cut or extend the electrodes
Install the bayonet mount
Install, calibrate and seal
For Dominator BT: configure from your smartphone. Detailed mounting instructions and torque values are covered in the downloadable installation manual — see Documentation Center.
Real Dominator installation on a truck fuel tank
Calibration doesn't always mean filling the tank step by step
Measured filling / draining
Build the level-to-volume table by recording fuel added or drained in known steps.
Tank geometry
Calculate the table from the tank's known dimensions and shape.
Import an existing table
Already have a height-volume table for this tank? Import it directly.
Designed for integration with GPS tracking and control systems
Dominator speaks the protocols your telematics stack already uses.

Frequently asked questions
Choose wired for permanent installations with a direct interface to your GPS tracker. Choose Dominator BT when running a signal cable is difficult, costly, or impossible — trailers, stationary tanks, hard-to-reach mounting points.
In most cases yes — see the compatibility block and use "Check compatibility" to confirm your exact tracker model.
Yes. See the installation guide in the Documentation Center for the cutting procedure.
Yes, with modular electrode extensions. Maximum length and limitations are listed in the current manual.
To get output in liters you need a tank calibration table — built by filling/draining, from tank geometry, or imported if you already have one.
Supported fuel types depend on the exact modification — see the current datasheet for the full list of measured media.
Yes, provided the installation instructions for non-metallic tanks are followed.
Yes, with the appropriate mounting geometry and sealing kit for curved surfaces.
In most cases yes. Existing factory ports can sometimes be used if the design and manual allow it.
On digital buses (RS485/CAN) this is possible if your terminal supports multiple addressed devices — see the protocol documentation for addressing rules.
