In simple words
A fuel sensor measures the fuel level in the tank and sends it with GPS data, so you can see fuel use and sudden drops.
Step by step
A probe is fitted inside the tank
It measures the fuel level
The tracker sends the reading with location
The software shows fuel use by trip
You get an alert on a sudden drop
Limits to know
Readings change on slopes and in a moving vehicle. Good calibration and filtering reduce errors, but not completely.
Questions we hear often
Does it work in any tank?
Fitting depends on tank shape and size. Share your vehicle details.
Is calibration needed?
Yes. We calibrate during fitting.
Can it show theft?
It shows sudden drops. It does not stop theft.
