Fuel drops

The Fuel drops module is designed to continuously monitor, detect, analyze, and classify fuel level anomalies in truck fuel tanks using telematics data. Its primary purpose is to help fleet owners identify fuel losses, understand the root causes, and take corrective or preventive actions to reduce operational costs, prevent fraud, and improve asset security. Any suspicious events (based on a configured alarm threshold) are logged in the dashboard and can be treated by the dispatcher.

1. From the left navigation pane > click Fuel drops. The Fuel drops page is displayed. Fuel drop e+vents are triggered based on the configured alarms in Settings. When an alarm is triggered, it is displayed under Suspicious events.
2. Click an event to consult its details. The Fuel drop details are displayed on the right pane.
   • Suspicious events are triggered events that have not been treated yet.
   • Resolved events are events that have been treated (See Assign tag)

Assign tag #

In order to treat an incoming suspicious event, a tag must be assigned.

Click Assign tag in the event detail page, and mark the event as Theft or Not theft, and insert a subtype:

• Theft: These refer to intentional, unauthorized removal or manipulation of fuel.
  

Subtype	Description	Indicators
T‑junction (Fuel Line Tapping)	A T‑junction is an illegal connection added to the fuel line, allowing fuel to be siphoned while the engine is running or parked.	Steady fuel loss during driving, unexplained consumption increases.
Fuel Drain	Direct removal of fuel from the tank using external means such as hoses, drilling, or opening the tank.	Sudden fuel drop while the vehicle is stationary, often overnight or during rest stops.
Fuel Contamination	Non‑fuel substances (water, chemicals, or impurities) are added to the tank. Forcing the tank to be emptied or cleaned for decontamination.	Engine malfunction, abnormal fuel sensor readings, maintenance reports of poor fuel quality.
Invoice Manipulation	Falsifying fuel purchase records to cover unused, resold, or stolen fuel.	Mismatch between invoiced fuel, tank capacity, and fuel sensor data.
Odometer Reprogramming	Altering vehicle mileage to mask abnormal fuel consumption.	Inconsistent mileage records, discrepancies between GPS distance and odometer readings.

• Not theft: These refer to unintentional or legitimate fuel losses.
  

Subtype	Description	Indicators
Maintenance	Fuel loss caused by authorized maintenance or repair activities.	Fuel drops aligned with workshop visits or maintenance logs.
Technical Issue	Fuel loss or incorrect reporting due to mechanical or sensor problems.	Erratic fuel readings, inconsistent data without supporting behavioral evidence.

Click Save. The event has now been treated and will be moved to the Resolved events section of the overview page.
