TL;DR
Fuel theft in fleets takes three forms: siphoning from tanks, unauthorized refueling with pocketed receipts, and fuel card fraud. IPTech deploys capacitive fuel level sensors (±1% accuracy), geofenced authorized fuel stations, and CAN bus fuel consumption analysis. Typical result: 15-25% fuel cost reduction in the first quarter.
Three Types of Fuel Theft
Siphoning: Driver or third party drains fuel from the tank after hours. Common with trucks parked overnight at unsecured locations.
Receipt fraud: Driver refuels 50 liters, submits a receipt for 80 liters, pockets the difference. Especially common with cash-based refueling.
Fuel card misuse: Driver uses the fleet fuel card to fill a personal vehicle or sells fuel to a third party. Hard to detect without volume tracking.
Layer 1: Fuel Level Sensors
A capacitive fuel level sensor installs inside the fuel tank. It measures the actual fuel level with ±1% accuracy, reporting every 30 seconds. The platform draws a fuel graph over time. Any sudden drop outside a refueling event = theft alert.
Layer 2: Refueling Geofences
Authorized fuel stations are geofenced. The platform matches refueling events (fuel level increase) with location. If fuel goes in while the truck is not at an approved station, something is wrong. If the truck is at a station but the volume doesn't match the receipt amount — the discrepancy is flagged.
Layer 3: CAN Bus Consumption Analysis
For vehicles with CAN bus (most modern trucks), the tracker reads actual fuel consumption from the engine ECU. Compare consumed fuel vs. refueled fuel vs. current level. The math must balance. If it doesn't, the system identifies exactly where the fuel went missing — which trip segment, which stop.
Fleets deploying all three layers see 15-25% fuel cost reduction within the first quarter. ROI on fuel sensors alone is typically 2-3 months.
