Generator Monitoring & Fuel Management in Pakistan
A generator runs unattended for hours with a large accessible tank. On most sites it is the single biggest fuel loss.
VouchTrack monitors generators remotely across sites: run hours for service intervals and billing, continuous tank level with siphoning alerts, power-failure and start/stop notification, and a per-site consumption report. It works the same way on telecom towers, factory backup sets and construction gensets.
Sensor, network, dashboard
The sensor reports over the mobile network to the same platform that runs our vehicle tracking, so this sits alongside your fleet rather than in a separate system with a separate login.
- One dashboard for vehicles, sites and sensors
- Alerts by app, SMS, WhatsApp and email
- Scheduled reports and a documented REST API
- Installed and supported by our own technicians
How generator and energy monitoring actually works
A generator burns fuel whether or not anyone is watching, and the site diary is written by the person with the most reason to round it. Measuring it directly removes the argument.
Scroll the diagram sideways to follow all four stages.
A capacitive probe replaces the guesswork
The factory float gauge on a genset tank resolves about a quarter of a tank — useless for spotting a fifty-litre loss. A capacitive probe cut to the depth of the tank measures continuously and resolves changes of a few litres, which is the difference between knowing fuel went missing and suspecting it.
Probe cut to tank depth · few-litre resolution · calibrated per tank
Run hours are counted, not estimated
An engine-hours input records when the set is actually generating, separately from when it is merely powered up. That single number turns fuel into a rate — litres per running hour — and a rate is comparable across sites in a way a monthly total never is.
Engine-hours counter · optional kWh input · per-site baseline
The platform separates consumption from loss
Fuel falling while the engine runs is consumption. Fuel falling while the engine is off is not. The system compares each drop against the run state and against that unit’s own established burn rate, so a genuinely thirsty old set does not get flagged as theft and a siphon at 3 a.m. does.
Burn-rate baseline per unit · engine-off drop detection
Refuelling is reconciled against the invoice
Every rise in level is logged with its time, size and location, so the delivery you paid for and the fuel that entered the tank are two numbers you can put side by side. Most sites find the gap in the first month, and most of it is not dramatic theft — it is short deliveries nobody was in a position to challenge.

What you actually get
Fuel level, continuously
A capacitive probe in the tank produces a curve. Consumption slopes gently; a drop with the set switched off does not.
Run hours for service and billing
Hours are metered rather than logged by hand, so maintenance falls due at the right point and hire is billed accurately.
Start, stop and power-failure alerts
Know when mains power failed, when the set picked up, and whether it actually started.
Consumption per site
Litres per running hour, compared across sites — which is how you find the one that is quietly leaking.
Works without a vehicle
The unit is wired to the genset itself, or fitted as a self-powered tag where wiring is not practical.
Numbers, not just a live reading
A live value tells you the moment. The reports tell you the trend, which is what a budget conversation actually needs — scheduled to your inbox and exportable to Excel, CSV or PDF.
See the reportingThe difference it makes
Each of these is an outcome plus the mechanism that produces it, because a benefit without a mechanism is just a claim.
Losses measured in litres, not suspicions
A timestamped, located drop with the engine off is a fact. It ends the conversation that a monthly total can never settle.
How: Continuous level sensing correlated with engine stateCost of power, comparable across sites
Fuel per kilowatt-hour makes a well-run site and a badly-run one visible next to each other, which is where the savings actually come from.
How: Run hours and optional kWh metering per unitThe invoice checked against the tank
You paid for 1,000 litres. The tank rose by 890. Without a probe, that difference is invisible every single month.
How: Refuel event logging with volume and timestampSites with nobody on them still report
Telecom towers, remote pumping stations and construction compounds are exactly where losses concentrate, because nobody is there.
How: Standalone device with its own power and SIMService scheduled on real run hours
Servicing on the calendar over-services light units and under-services hard-worked ones. Run hours fix both.
How: Engine-hours thresholds driving maintenance remindersGensets beside vehicles
If you already track vehicles with us, generators appear in the same login with the same alert rules and the same report scheduler.
How: Shared platform, rules engine and APIFigures shown are typical of what operators report rather than a guarantee. What your fleet recovers depends on where you are starting from — we would rather set the expectation honestly than win the order and miss it.
The technical detail
The questions a technical evaluator asks before a commercial one does. If something you need is not here, ask — we will answer it rather than route you to a brochure.
| What is measured | Fuel level, engine run hours, engine on/off state, refuel and drop events, position, and kWh where a meter is fitted. |
|---|---|
| Sensor type | Capacitive fuel probe cut to tank depth, calibrated to that tank’s geometry. |
| Resolution | Typically a few litres, depending on tank shape and depth; calibration table built per installation. |
| Reading interval | 60 seconds, with event-triggered reporting on any rapid level change. |
| Connectivity | Multi-network GSM SIM; on-board buffering at sites with intermittent coverage. |
| Power | Genset supply with internal backup so a shutdown does not stop reporting. |
| Outputs | Live level and run state, drop and refuel alerts, litres per running hour, litres per kWh, monthly reconciliation export, REST API. |
| Installation | By our technicians. Requires tank access and a short shutdown window; typically one working day per site. |
