Diesel (AGO) Fuel Monitoring for Trucks and Tanks in Nigeria
See every litre of AGO in your trucks, storage tanks and generators, and get an alert the moment diesel is refilled or drained, wherever you are.
₦360,000 per truck: initial setup & installation · renewal ₦35,000/yr
Diesel (automotive gas oil, or AGO) is one of the biggest running costs for Nigerian transporters, factories, telecom sites and estates, and losses through siphoning, short supply and inflated refill records are hard to prove. Our diesel fuel tank monitoring in Nigeria measures the AGO in each truck or tank continuously, so you know how much you have, how much was added, and exactly when and where it dropped.
We fit calibrated capacitive fuel level sensors, including Eurosens wired and Bluetooth probes, in truck tanks, generator day tanks and static storage tanks. Each sensor reports to GPSFleetTrack Pro through a tracker with a multi-network data SIM. You get a live fuel graph, refill and drain reports in litres, and alerts within seconds of a sudden change.
Because fuel data sits next to GPS tracking, every refill and drain is tied to a location, time, driver and engine status. You can see whether diesel left the tank while the truck was parked at night, whether the litres on a supply receipt actually arrived, and how consumption compares with distance and engine hours.

What you get
- Real-time alerts for every AGO refill and drain
- Proof of the actual litres delivered by suppliers
- Evidence of siphoning: time, place, litres and driver
- Accurate consumption per truck, trip and generator
- Remote stock levels without manual dipping
- Lower diesel bills, typically within the first months

Industries we serve
AGO monitoring for diesel trucks
For tankers, haulage trucks, tippers and buses, a level probe is installed through the top of the fuel tank and connected to the tracker. The platform learns the tank shape during calibration, so every reading is shown in litres.
- Refill alerts show how many litres went in, at which filling station and at what time, so you can check them against the supply receipt.
- Drain alerts fire when the level drops while the engine is off or the truck is stationary: the typical pattern of siphoning.
- Consumption per trip compares litres used with kilometres driven, so wasteful routes, idling and over-revving show up.

AGO monitoring for storage tanks and generators
For diesel storage tanks at depots, factories, estates, hotels, hospitals and telecom sites, we install a long-range sensor and a fixed telemetry unit with backup power. Generator day tanks can be monitored together with generator running hours.
- Delivery verification: see the exact litres received from each AGO supplier delivery.
- Stock levels for every site on one dashboard, with low-level alerts before you run out.
- Generator efficiency: litres per running hour for each generator, to spot faults and fuel theft.

Managed on GPSFleetTrack Pro
Every tracker we install reports to our own cloud platform. Here is what you will see.
Fleet dashboard: Key figures for the whole fleet at a glance: distance, utilisation, idling, safety score, alerts and fuel used.
Live tracking: Every vehicle on one map with status filters for moving, idle, stopped and offline, refreshed in real time.
Vehicle details: Zoom into any vehicle for its exact address, ignition, engine hours, speed and sensor data.
Smart alerts: Over-speed, geofence, ignition, tamper, fuel drain and ADAS/DMS camera alarms sorted by priority.
Maintenance: Service reminders by mileage, engine hours or date, with parts, service logs and costs.
Tasks & dispatch: Create jobs with pickup and destination, assign a vehicle and track progress against trigger radiuses.
Convoy tracking: Real-time escort and convoy monitoring that warns when vehicles drift too far apart.
History playback: Replay any trip with stops, speeds and events, then export to PDF or Excel.
How we deliver
Survey
We check each truck or tank: shape, size, access and the right sensor length and type.
Installation
Technicians drill, seal and fit the probe safely, then connect it to the tracker or telemetry unit.
Calibration
The tank is filled in measured steps so the platform converts readings into accurate litres.
Alerts & training
We set refill and drain thresholds and show your team how to read graphs and reports.
