The problem
Fuel theft and consumption nobody can explain
Fuel is one of the largest operating costs of a fleet, and without a real tank-level reading all you see is the final invoice. That makes it hard to tell normal use from waste or unauthorised drawing.
- Fuel drawn from the tank while the vehicle is parked.
- Refuelling that does not match the receipt.
- Higher-than-normal use from driving style or idling.
- Similar vehicles with very different consumption and no clear reason.
How it works
How the fuel sensor works
The Omnicomm LLS 6 AI probe is fitted vertically inside the tank and measures the fuel level capacitively, then passes the reading to the tracker in the vehicle. The tracker sends the reading with position and time to the platform over the mobile network.
Every refuel and every drop in level then appears on the map and in reports, not only on the invoice.
We install the sensor in the tank and connect it to the tracker.
We build a calibration table for each tank.
The device sends level, position and time continuously.
The platform turns readings into events and reports.
Dashboard and alerts
What you see and receive
Level curve per vehicle with position and speed.
When and where fuel was added, with an estimated quantity.
A sudden drop in level with time and location to review.
Per vehicle and per trip, and per driver when the driver is linked to the vehicle.
Fuel consumption reports you can compare across vehicles and periods.
For sudden drops or low level. More reports in the fleet management software.
Calibration
Fuel tank calibration
Tanks differ in shape, so the probe reading alone is not enough. We calibrate each tank individually so that the reading becomes litres you can rely on in reports.
We check its shape, fitting opening and the right place for the probe.
We fill the tank with known quantities, stage by stage.
We record the sensor reading at each stage to build the table.
We review the readings with your team before reports are relied upon.
Applications
Supported vehicles and tanks
Haulage and distribution trucks. See also truck tracking.
Construction and site equipment.
Fuel and consumption monitoring for diesel generators.
Passenger buses and specialist transport fleets.
Installation depends on the tank shape and fitting opening, and we inspect your vehicles before quoting.
Accuracy
Accuracy and what affects it
Fuel reading accuracy depends on calibration quality, tank shape, vehicle tilt and fuel movement while driving. That is why we review the readings with you after calibration.
Accuracy up to 99.5% after calibration, per the manufacturer’s specification.
The Omnicomm LLS 6 AI uses the manufacturer’s FuelScan technology to adjust readings automatically when fuel properties change between stations, and on-sensor processing to smooth readings and detect refuels and drains at low thresholds. Source: Omnicomm product page.

Frequently asked questions
Fuel sensor questions
What is a fuel sensor and how does it detect fuel theft?
A fuel sensor is a probe fitted inside the tank that measures the fuel level continuously. When the level drops quickly while the vehicle is parked, or outside its normal consumption pattern, the platform records a drain event with the time and location for you to review.
Does it work on trucks, heavy equipment and generators?
Yes. It is fitted to diesel tanks on trucks, buses, heavy equipment and generators. Installation depends on the tank shape and the fitting opening, and we inspect the tank before quoting.
Do I need a tracker as well?
Yes. The sensor connects to the tracker, which sends its readings with position and time over the mobile network to the platform. If you already have a tracker installed, we check compatibility before installation.
What does the dashboard show?
A fuel level curve per vehicle, refuel and drain events, consumption per trip and per vehicle, periodic reports, and alerts for sudden drops or low level.
Is the fuel tank calibrated?
Yes. Each tank is calibrated individually by filling it in stages with known quantities and recording the sensor reading at every stage, because tank shape affects the link between level and volume.
How accurate is the reading?
Accuracy up to 99.5% after calibration, per the manufacturer’s specification for the Omnicomm LLS 6 AI. Real-world readings are affected by calibration quality, tank shape and vehicle tilt, so we review them with you after calibration.
How much does a fuel sensor cost?
Price depends on the number of tanks per vehicle, probe length and number of vehicles. Send us your vehicle types and counts on WhatsApp or by phone and we will prepare a quote.
Can it be fitted to my existing vehicles?
In most cases yes, after we inspect the tank and fitting opening. Our own technicians install at your site and coordinate with vehicle downtime.
