"Where did the diesel go?"
Answered before the driver can explain it away.
GPS-integrated fuel monitoring that works with any sensor type — real-time levels, theft alerts, multi-tank support, and refuel reports your fleet register can't argue with.
Diesel is your biggest running cost. It's also your least-tracked one.
Fuel routinely runs close to half of a diesel fleet's operating cost — and a logbook can't catch a siphoned tank, an inflated fill-up, or an engine idling for an hour at a dhaba. A fuel sensor wired to your GPS tracker can.
Fuel theft
Sudden level drops while the vehicle is parked or idle are flagged the moment they happen — with the exact location and time.
Inflated refuels
Every top-up is measured by the sensor itself, not the fuel slip — so a driver claiming a full tank can be checked in seconds.
Idle burn
Engine-on, wheels-off time is often the quietest leak in a fleet — reports show exactly which vehicles and drivers idle the most.
Compatible with any fuel sensor
The biggest limitation with most fuel platforms is that they only work with one sensor brand. Ours doesn't lock you in — it's built to work with the sensor you already have, or the one that best fits your tank.
- Works with ultrasonic fuel sensors
- Works with capacitive fuel sensors
- CAN-bus fuel data support for compatible vehicles
- Fuel flow meter integration for tankers and dispensing points
- Works across trucks, tankers, generators, and construction equipment
- Flexible integration for custom fleet setups
From tank to dashboard in three steps
Fit the sensor
A fuel level sensor is fitted inside the tank and wired to your GPS tracker — usually done in under 90 minutes by a certified technician at your yard.
Stream the data
The sensor reports fuel level to the cloud alongside GPS location, ignition status and speed — as often as every 30 seconds.
Get the alert
Theft alerts, refuel confirmations and consumption reports land in the Alphatech app and dashboard — no manual logbook required.
Monitor every tank, every sensor, on rough roads
Get complete visibility of fuel activity from one platform — including vehicles that don't fit the standard single-tank, single-sensor setup.
Multiple tanks, one vehicle
Some heavy vehicles and tankers run more than one fuel tank — the system monitors all of them together on a single screen.
Multiple sensors, one tank
Fuel sloshes on rough roads and slopes, which can throw off a single reading. Using more than one sensor per tank keeps the number accurate.
Smart fuel reports
See how fuel is used across trips, idling, and long routes, and compare mileage against usage to spot wastage early.
A complete GPS fuel monitoring system, not just a sensor
Real-time fuel level
Live tank levels for every vehicle in the fleet on one dashboard.
Fuel theft & drain alerts
Instant alerts the moment fuel drops while a vehicle is stationary.
Refuel verification
Every top-up logged with quantity, time and place, checked against the bill.
Idle fuel waste
Flag vehicles burning diesel with the engine on, wheels not turning.
Consumption reports
Compare expected vs. actual mileage per vehicle, route and driver.
Geofenced fuel stops
Get an alert on any off-route refuelling outside approved stations.
Multi-tank & multi-sensor
Monitor several tanks or sensors per vehicle from one screen.
Driver fuel impact
See how individual driving habits affect fuel consumption.
Route fuel analysis
Spot which routes consume more fuel than they should.
Fill & drain history
A complete log of every fuel-in and fuel-out event, per tank.
Live fuel dashboard
Fuel activity and trends for the whole fleet, at a glance.
DG set & generator monitoring
Track fuel for stable assets like generators, not just vehicles.
Capacitive, ultrasonic or float — which fuel sensor fits your fleet?
We fit the sensor to the vehicle, not the other way around. Here's how the three common types compare.
| Sensor type | Accuracy | Best for | Installation |
|---|---|---|---|
| Capacitive fuel sensor | High, calibrated to tank shape | Trucks, buses & tankers with a steady tank geometry | Fitted inside the tank, calibrated on-site |
| Ultrasonic fuel sensor | High, stable through motion | Vehicles on rough roads or frequent stop-start routes | Mounted on the tank exterior — no drilling |
| Float / analog sensor | Moderate | Tractors, generators & budget fleets | Simple fitment, lowest cost of the three |
Exact accuracy and pricing depend on your tank's size and shape and the vehicle type. Our team recommends a sensor after a quick look at your fleet — request a fleet quote for an exact number.
Wherever diesel goes missing
Fuel monitoring system — FAQ
What is a fuel monitoring system?
It's a fuel level sensor fitted in the vehicle's tank, wired to a GPS tracker, reporting to cloud-based software. Together they show real-time diesel levels, theft alerts and consumption reports for every vehicle in a fleet.
Can fuel be tracked without a fuel sensor?
Fuel can be estimated from a vehicle's OBD/CAN data without a dedicated sensor, but this only gives an approximate figure. A physical sensor gives an accurate, real-time reading and is the only reliable way to catch theft.
Does this work for generators and DG sets, not just vehicles?
Yes. The same sensor and monitoring approach works for stationary assets like DG sets and emergency generators, tracking fuel level and consumption patterns for maintenance planning.
Can multiple tanks or multiple sensors on one tank be monitored?
Yes, the system supports more than one tank per vehicle and more than one sensor per tank, which improves accuracy on vehicles that see rough roads or slopes.
What fuel alerts are available?
Alerts cover sudden fuel drops, refuel events, and idling-related fuel waste, alongside standard driving alerts like harsh braking and overspeeding.
Can I get custom fuel reports for my fleet?
Yes, reports can be tailored to your fleet's structure — by vehicle, route, driver, or depot — rather than a single fixed format.
How much does a fuel monitoring system cost in India?
Pricing depends on the sensor type, tank size and number of vehicles in your fleet. Request a demo and our team will size a system for your exact vehicles.
