What it is. What it does. Where it fits.
A tank monitoring system that provides local and remote visibility of stock, ullage, deliveries, throughput and alarms.
What does it do?
It converts measured liquid level into useful stock, ullage and tank-status information for the site team.
Who normally uses it?
Sites that need clearer visibility of stored fuel or AdBlue for delivery planning, stock checks and exception review.
What does it connect to?
Compatible tank probes, the local display and Fueltek reporting software where remote monitoring is included.
Where does it fit?
Alongside the tank and dispensing system, adding stock visibility to the transaction information recorded at the pump.
TankWatch equipment
Hardware Probes, display and alarms.
Tankwatch monitors the fluid inside a storage tank using calibrated probes connected to a local control panel. It gives delivery drivers and site teams a clear local interface while also supporting remote stock management through Fueltek TMO reporting software.
Key capabilities
What the Tankwatch provides
- Displays current stock, available capacity (ullage), stock movements, deliveries and throughputs.
- Detects unusual stock movements and can provide early warning of possible leakage.
- Shows alarm status audibly and visually at the fuel tank.
- Can disable a pump when the tank is empty.
- Can operate independently or integrate with other Fueltek fuel management systems.
- Suitable for new installations and straightforward retrofits to existing tanks.
Local tank control
Clear information where deliveries happen.
- Probes connect to a control panel mounted locally at the tank.
- The bright, heavy-duty display remains readable in daylight.
- Helps delivery drivers make safe and secure deliveries.
Accurate measurement
Calibrated tank readings can contribute to FMO stock visibility alongside recorded fuel issues; the probe remains matched to the tank geometry.
- High-accuracy pressure sensor.
- Individually calibrated to account for tank geometry.
- Tracks current stock, ullage, delivery and throughput movements.
Product level
A stock measurement supports inventory and ullage information. It does not by itself identify water at the bottom of the tank.
Water-in-fuel sensing
Water-ingress alerts are available with the appropriate TankWatch sensing arrangement. Water inside the primary tank and liquid in the bund are monitored as separate conditions.
Bund monitoring
A bund sensor concerns liquid in secondary containment. It is not a test of fuel quality inside the primary tank.
Microbial contamination
Neither a bund alarm nor water indication diagnoses diesel bug. Suspected contamination requires appropriate sampling and specialist investigation.
Fueltek FMO
Tank stock within your fuel-management view.
TankWatch integrates with FMO so measured tank stock can be compared with recorded dispensing and calculated book stock. TMO (Tank Manager Online) provides the dedicated browser-based tank-reporting service.
- TMO reports include site, tank, product, current stock, previous-day deliveries and throughput, and estimated days of stock remaining.
- Authorised users can access TMO from an internet-connected PC. Scheduled reports can be emailed daily, weekly or monthly to configured recipients.
Example FMO screens · Views and records depend on the connected equipment and account permissions. Select an image to view it full size.
FMO’s Tank Gauges screen shows tank details, received readings and level history where TankWatch is connected.
Tank View presents book and gauge figures together, with tank status and update times. These are FMO views, separate from TMO reporting.

Monitoring scope
Local alarms, pump interlocks and remote notifications
Local warning and remote notification
TankWatch supports local audible and visual warnings, with configurable remote email or text notifications. Available alarms and notifications depend on the installed sensors, communications service and configuration.
Pump interlocks
Pump isolation requires a compatible interface and configured trigger. A displayed low-stock warning and a pump interlock serve different purposes.
Current communication options
TankWatch supports 4G/LTE mobile data, Wi-Fi and Ethernet connectivity, with the communications module matched to the network available at your site. Roaming SIMs and connection options.
Optional email or text alerts notify nominated recipients using the installed sensors, thresholds and communications service. Low-level, overfill, bund-leak and unusual-stock-movement indications remain distinct; water-ingress alerts need the appropriate sensing arrangement.
Technical detail
Tank measurements and protective functions
The tank’s stock display and its protective functions should be specified as distinct parts of the installation.
| Function | What the information means | What to define |
|---|---|---|
| Stock and ullage | Calculated liquid quantity and remaining space derived from the configured measurement. | Tank geometry, probe arrangement and agreed operating levels. |
| Delivery and movement records | Changes over an identified period. | Time alignment, detected versus recorded deliveries and other outlets. |
| Bund leak indication | A separate containment condition to investigate. | Required sensor arrangement and response; do not infer it from a normal stock reading. |
| Overfill / low-level response | A warning or configured protective action. | The trigger, local indication, remote notification and any required interlock. |
| Remote availability | The latest received reading and communication status. | Reading age and communication failure handling before relying on the display. |

Tank geometry, stored product, probes, alarms and communications determine the monitoring arrangement.
See all product sheets and download guidance →Tank shape, probe arrangement, power and communications can affect the final Tankwatch setup, so those details should be checked for each tank rather than assumed from a standard configuration.

Tankwatch adds stock visibility rather than dispensing control. Compare it with Fueltek’s terminals and dispensers when the wider project also needs authorised fuel issue, metering or transaction reporting.

Need stock visibility, transaction control or both?
Tankwatch measures tank stock and movement. FT4000 controls authorised fuel issues and records transactions. Compare the two roles when specifying monitoring alongside dispensing control.
