Intelligent Fuel Monitoring Product

Digit D-Fuel

Know What’s In The Tank. Know Where It Went.

Fuel loss is rarely obvious — it hides in small discrepancies. The Digit D-Fuel measures fuel continuously inside the tank itself, detecting refuelling, abnormal drops, siphoning and leaks as they happen. Because measurement lives in the vehicle rather than in a logbook, explanations and disputes are replaced with evidence. This is control at the source.

Why It Exists

Fuel Loss Is Rarely Obvious

Fuel is one of the largest operating costs in any fleet, yet its losses hide in plain sight: small discrepancies, inconsistent readings, unexpected refuelling events, inflated consumption and unclear accountability. Because the truth lives inside the tank while the records live on paper, uncertainty becomes the normal state — and disputes replace decisions.

The Digit D-Fuel removes human dependency from fuel measurement. Installed directly into the fuel tank, it measures continuously and detects refuelling, abnormal drops, siphoning and leaks in real time, then syncs verified data for reporting — no driver input, no manual logs. As a result, accountability is built into the vehicle itself: measurement, detection and reporting at the source.

What It Does

Digit D-Fuel: Real-Time Accountability Inside The Tank

Real-time fuel level monitoringLive levels across the entire fleet, anytime and anywhere — measured continuously inside the tank, not estimated.

Immediate fuel theft alertsThe moment unauthorised fuel removal occurs, you are notified — with exact location and timestamp for quick action.

Accurate refuelling trackingEvery refuelling event logged with precision — location, date, time and litres added, so fills reconcile against invoices.

Custom consumption reportsLitres per kilometre, litres per hour and percentage consumption changes — generated automatically, then delivered as reports.

Siphoning & leak detectionAbnormal drops are flagged as they happen, so a slow leak and a quick siphon both surface immediately.

Multi-tank & platform integrationSupports up to 3 fuel tanks per vehicle, while fuel data flows hand-in-hand with DigitFMS vehicle tracking on one platform.

FAQ

Digit D-Fuel: FAQs

What is the Digit D-Fuel?

An intelligent fuel monitoring product installed directly into the vehicle’s fuel tank. It measures fuel continuously and reports in real time, so visibility and accountability live inside the tank rather than in a logbook.

How does Digit D-Fuel detect fuel theft?

Because measurement is continuous, siphoning and abnormal drops are detected as they happen — then an immediate alert fires with the exact location and timestamp, so action can be taken quickly.

Does it rely on drivers or manual logs?

No. Measurement, detection and reporting happen continuously and automatically, while verified fuel data syncs to cloud reporting — human dependency is exactly what it removes.

What tank configurations does it support?

Up to 3 fuel tanks per vehicle — single, dual or multi-tank configurations — and it is deployed directly within fleet vehicles where fuel risk is high and accountability matters.

Does Digit D-Fuel integrate with vehicle tracking?

Yes — it works hand-in-hand with DigitFMS vehicle tracking on one unified platform. In addition, tracking units like the Digit N-Link and Digit SS integrate D-FUEL data directly, so fuel and movement tell one story.

The Digit D-Fuel is installed and supported by DigitFMS, a PSiRA-registered security service provider. Insurance outcomes depend on your insurer and policy terms.

Every Drop Counts

Don’t Let Fuel Wastage Drain Your Profits

If fuel is one of your largest costs, then it deserves its own sensor. After one short form, a DigitFMS specialist comes back within one business day to spec the D-Fuel for your fleet — tank configurations, installation, and how it connects to the tracking you already run.
