Fuel Level Monitoring

Overview

Know exactly how much fuel is in every tank, every second of the day. A precision fuel-level sensor sits inside the tank and reports the real level to your GPS tracker with around 1% measurement accuracy and millimetre-level sensitivity to change — independent of the OEM dashboard gauge, which typically reads in quarter-tank steps and cannot tell a refuel from a drain. From that one signal the platform separates three things the dashboard cannot: a legitimate refueling event (a controlled rise at a known time and place), a drainage or siphon (a sharp fall outside the expected pattern), and continuous consumption during operation. Each event is timestamped against location and driver, so fuel data lines up with where the vehicle was and who was responsible. Operators running this approach worldwide typically report meaningful fuel-cost reductions — documented cases include 150 trucks in Mexico (25% fuel-expense decrease) and stationary site tanks up to 300,000 litres where theft was eliminated entirely.

Challenges

Dashboard gauges are imprecise. A 200-litre swing can read as "half full" on a typical sender resistor, so spot checks miss everything between the marks.
Refueling and drainage both reduce tank level. Without timestamped events and location, gauge readings alone cannot tell a legitimate fill from theft.
Mixed fleets carry different tank shapes. Volume readings must be calibrated per vehicle — a generic "litres remaining" figure is worse than no number at all in a finance report.
Tank sender wiring is fragile and OEM-specific. Wireless / BLE-based sensors deploy on trailer swaps, daily rentals, and unusual tank geometries without running new cabling.
Stationary fuel storage at depots and remote sites has no gauge at all. A 300,000-litre site tank is typically dipsticked by hand once a day — the gap most fuel theft operates inside.

Benefits

You see the real number, not the gauge's guess. Litre-accurate readings calibrated per tank shape, accurate to about 1%.
Every refuel reconciles against your fuel card. Time + location + tank-level rise turn a monthly statement into a verifiable event log; depot pump versus roadside fill is unambiguous.
Drainage and siphon attempts trigger alerts in seconds. The GPS tracker pins the event to vehicle, route, and driver — so finance attributes loss to an event, not a person.
Trailers, rentals, and oddly-shaped tanks are covered. BLE sensors run on internal battery for around five years and pair to the in-cab tracker over Bluetooth — no wiring back to the cab.
The same sensor family scales from a 60-litre van to a 300,000-litre site tank. One product line covers vehicles, trailers, stationary storage, and generators — no separate stack per asset class.
