One sensor platform
Wired or wireless?
Same measuring platform, two installation philosophies. Pick the branch that matches your tank, vehicle and tracker.
Wired Dominator
For permanent installations with direct connection to a GPS/GLONASS tracker, display or control system.
- RS485 / RS232
- CAN J1939
- Analog / Frequency
- LLS / MODBUS
Dominator BT
Autonomous fuel level sensor with Bluetooth Low Energy. No signal cable routing between the sensor and receiver.
- Bluetooth BLE
- Built-in battery
- Up to 200 m*
- Smartphone configuration
* Direct line of sight.
Why Dominator
Built to be installed, serviced and reused
Bayonet mounting
Fast removal without dismantling the tank mount.
Fuel volume inside the sensor
Level in — liters out.
Temperature compensation
Stable measurements from −40 to +85 °C.
Fuel theft detection
Fuel drain detection and alarm output.
Built for vehicles
Automotive connector. IP67. Self-diagnostics.

Installation
Four steps on the vehicle
01Measure tank depth
02Cut or extend the electrodes
03Install the bayonet mount
04Install, calibrate and sealFor Dominator BT: configure from your smartphone. Full mounting instructions and torque values are in the downloadable installation manual — see Documentation Center.
Tank calibration
Tank calibration doesn't always mean filling the tank step by step
Measured filling / draining
Build the height-volume table from controlled portions.
Tank geometry
Calculate the table from tank shape and dimensions.
Import an existing table
Reuse a height-volume table you already have.
