Fuel Level Sensors
Accurate fuel level readings directly from the tank, eliminating fuelling fraud and siphoning while providing clear evidence of fuel levels.
Fuel represents a significant operational cost for any fleet, often comprising as much as one-third of total expenses. Our tailored fuel management systems provide visibility into expenses, prevent fuel theft, and streamline fuel-related operations. With our comprehensive fuel control solutions, we deliver valuable data about fuel expenses for every vehicle or machinery in your fleet.
Significant discrepancies between fuel card records and actual tank levels are one of the most common – and costly – signs of fuel fraud or siphoning. FMSi’s fuel level sensors provide accurate, real-time readings directly from the tank, creating an independent data point that can be cross-referenced against fuel card transactions, driver logs, and odometer readings. Any significant mismatch is flagged immediately, giving fleet managers the evidence they need to investigate and act – rather than absorbing the loss as an unexplained variance at month end.
FMSi’s fuel control solution monitors tank levels continuously and generates instant alerts the moment an abnormal drop is detected – whether that’s a sudden unexplained decrease while the vehicle is stationary, a refuel that doesn’t correspond to an authorized fuel stop, or consumption figures that don’t align with the distance travelled. Every fuel event is timestamped, geo-tagged, and tied to a specific vehicle and driver, creating an auditable trail. The system doesn’t just flag suspicious activity after the fact – it deters it, because drivers know every drop of fuel is being accounted for.
Fuel typically represents up to one-third of total fleet operating costs – and a significant portion of that is recoverable through better visibility and controls. FMSi’s clients have achieved up to 50% reduction in fuel costs following deployment. The savings come from multiple directions simultaneously: eliminating theft and unauthorized usage, reducing idle time (which the system quantifies in both litres and cost), identifying vehicles with abnormally high consumption that require maintenance attention, and giving managers the comparative data needed to set and enforce consumption benchmarks across the fleet.
FMSi’s fuel management solution supports three hardware approaches that can be deployed across a mixed fleet. Fuel level sensors provide direct tank readings for vehicles where CAN-bus access is unavailable, insufficient or not accurate enough. Fuel flow meters track the actual fuel consumption – the exact volume of fuel consumed by the engine. CAN-bus integration extracts fuel data directly from the vehicle’s onboard system for compatible vehicles. All three data streams feed into the same FMSiTrack platform, giving a unified view regardless of the hardware mix across your fleet – so you’re not managing separate systems for different vehicle types.
The system generates detailed comparative reports that sit standard versus actual fuel consumption side by side for every vehicle in the fleet. Outliers – vehicles or drivers consistently consuming above benchmark – are immediately visible without anyone needing to build a spreadsheet. Idle time is calculated separately in both litres and cost, so the financial impact of excessive engine idling is quantified rather than invisible. This data can be used directly in driver performance reviews and to prioritize vehicles for maintenance inspection where consumption anomalies may indicate a mechanical issue rather than a behavioural one.
FMSi’s fuel control solution operates on real-time monitoring – alerts for fuel theft, abnormal consumption, and unauthorized fuel events are issued instantly, not surfaced in a weekly report. Operations staff receive notifications the moment a threshold is breached, whether that’s a sudden tank drop, a fuel fill outside an approved location, or consumption that deviates significantly from the expected figure for that route and vehicle. This means issues that previously compounded over weeks are now identified and addressed within hours.
FMSi’s Fuel Control Solution is a fully integrated enhancement within the FMSiTrack platform – not a standalone tool requiring separate login or data reconciliation. Fuel data is cross-referenced automatically against GPS position, journey records, driver ID, and vehicle maintenance data within the same platform. This means a single dashboard view connects fuel consumption with route efficiency, driver behaviour, and vehicle health – enabling the kind of informed decision-making that siloed fuel monitoring tools simply cannot provide.
