GPS Trackers with Fuel Sensors for Trucks
Track every gallon and every mile in real time
A GPS tracker with a fuel sensor reads the real fuel level in the tank, not the dashboard gauge. Top Tracking System pairs live GPS tracking with in-tank sensors, so you see fuel burn by truck and driver and get an alert the moment fuel is siphoned, on the same dashboard as your ELD.
What Top Tracking System GPS fuel sensors do
Live location
Every truck on one map in real time, so dispatch can reroute around delays and give customers accurate ETAs without a phone call.
Real fuel-level readings
An in-tank sensor reports the actual level continuously, more accurate than the OEM gauge or a fuel-card total.
Siphoning alerts
A sudden drop while the engine is off sends an instant alert with the time and location, so theft is caught the night it happens.
Geofencing alerts
Draw a zone around a yard, terminal, or fuel stop and get an alert when a truck enters or leaves it, day or night.
Route history
Replay any trip with stops, idle time, and fuel used, to cut miles and fuel off a regular lane.
Speed and idle alerts
Flags for going over a set limit and for long idle. Both burn fuel; speeding also drives up CSA.
Maintenance reminders
Schedule service by real odometer or engine-hour readings, so a PM is never missed and a breakdown never strands a load.
How GPS with fuel sensors works, in 3 steps
Wire the tracker, calibrate the tank sensor once, then watch fuel and location from the same dashboard.
- 01
Install and calibrate
The GPS unit is wired in and the tank sensor fitted, then calibrated on a full tank so readings match real gallons.
- 02
Data transmission
Location and fuel readings go to the cloud over cellular, and store on the device through any dead zone.
- 03
Fleet monitoring
The dashboard shows fuel level and location per truck, sends theft and idle alerts, and builds MPG and fuel-cost reports by truck or driver.
Why fleets choose Top Tracking System for fuel monitoring
We are a small US-based company built around trucking technology. The difference shows up in 3 places: the support you reach, the contract you sign, and the number of vendors you manage.
Focused on trucking since 2016. GPS, fuel and temperature sensors, ELD, and cameras are all we build.
One platform, one bill. Fuel sensors, GPS, ELD, and cameras run on the same dashboard, not 3 or 4 logins.
Support you can reach. Phone, email, and WhatsApp from a US-based team, on a month-to-month plan.
Fuel sensor questions carriers ask before they buy
Straight answers on fuel cards vs tank sensors, install, accuracy, theft alerts, DEF, and where to start.
1. What does a fuel sensor tell me that a fuel card doesn't?
A fuel card shows what you paid for at the pump. A tank sensor shows what is actually in the tank right now and how fast it is dropping. Together they catch off-truck fueling, siphoning, and a slow leak that a card statement would never reveal.
2. Will putting a sensor in the tank void my warranty or cause a leak?
Not when it is done right. The sensor mounts through the existing sender plate or a sealed port, with no cutting, so the tank stays sealed. A certified installer sets it up, and we confirm the fit for your tank type before install.
3. How accurate is it, and does it need recalibration?
After the one-time calibration on a full tank, readings are usually within 1 to 2 percent. That holds unless the sensor is moved or the tank is swapped, so there is no routine recalibration. The software adjusts for temperature changes in diesel volume.
4. Can it tell normal fuel use apart from theft?
Yes. Burning fuel while driving shows as a gradual drop tied to engine hours and miles. Theft shows as a fast drop with the engine off, often at night or off-route, and that is what fires the alert, with location and time attached.
5. Does this work on gas trucks and DEF, or only diesel?
The fuel-level sensor works on diesel and gasoline tanks. It does not read the DEF tank by default, but a second sensor can be added for DEF level if low-DEF derates are a problem for your fleet.
6. Do I need this on every truck or just the ones I suspect?
Start with the trucks where fuel spend does not match the miles, or that sit unattended overnight. Once a sensor pays for itself there, rolling it fleet-wide is usually an easy call. There is no minimum and no long-term contract.
