Fuel consumption and diesel level monitoring
Fuel is usually the largest operating line in a transport fleet, and the hardest to evidence. But "fuel monitoring" is not one solution: there are three different methods with different outcomes, and a supplier who sells you one as though it were all three will land you in trouble.
Three different methods — not synonyms
This table is the most important thing on the page. Read it before asking any supplier for a quote.
| Method | What it actually measures | Suits | Limits |
|---|---|---|---|
| In-tank level sensor | The fuel level inside the tank, from which sudden drops or refuelling are inferred. | Detecting unexplained drops, verifying refuelling quantities, and tracking consumption against distance. | Requires in-tank installation and calibration per tank shape. Readings are affected by vehicle incline and vibration, which is why they are read over intervals rather than as a single instant. |
| Vehicle network (CAN) data | What the vehicle itself reports about consumption or tank level, where its model exposes it. | Modern fleets whose vehicles expose this data, with no in-tank work. | An estimate from the vehicle, not an independent measurement. Support varies dramatically between models, and some trucks do not expose it at all. |
| Refuelling events | Level-increase events: when, where, and roughly how much. | Reconciling fuel invoices against what actually reached the tank. | Does not measure instantaneous consumption, and depends on the quality of the level reading. |
We do not publish a single accuracy figure for fuel solutions. Real accuracy depends on tank shape, calibration quality, installation method and duty cycle — and any number given before calibration is a promise, not a measurement.
What we review before recommending a fuel solution
- Tank shape, capacity and how many tanks the vehicle has — calibration differs fundamentally between a cylindrical tank and an irregular one
- Truck model and year, to establish whether CAN data is available and worthwhile
- Duty cycle: long intercity runs, or stop-start in-city distribution
- Whether the goal is detecting theft, reconciling fuel invoices, or measuring consumption efficiency — the goal determines the solution
- Whether the truck can be taken off the road for the time installation and calibration need
- Who will read the reports and act on them, because a solution nobody follows up saves nothing
About detecting diesel theft
What the solution does is show a drop in tank level that does not match the distance covered or running time, with the time and location of the event. That is a strong indicator, and in many cases enough to open an internal investigation.
But it is an indicator, not a verdict. The cause may be a leak, a calibration error, an anomalous reading from a steep incline, or an unrecorded refuel. We therefore advise treating an alert as the start of a review, and we help set thresholds so your supervisors are not buried in meaningless alerts.
And we do not promise a savings percentage. Any figure quoted before we have seen your fleet's data would be a guess, and guessing on a line item the size of fuel does you more harm than good.
