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

Installation
Four steps on the vehicle
- 01Measure tank depth
- 02Cut or extend the electrodes
- 03Install the bayonet mount
- 04Connect and configure
- Dominator BT: configure from your smartphone. Full instructions are in the downloadable manual.
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.
