How does AVI work?

1) The nozzle is inserted in the fuel tank. The vehicle tag details are validated by DiaLOG – vehicle data, odometer data, and/or information relating to engine running time are wirelessly transmitted during the authorisation process.

2) Communication between the vehicle tag and the nozzle unit localises the transaction to that specific nozzle and only then can fuel be dispensed. The system controls fuel type and prevents any unauthorised fuelling from taking place.

3) Once refuelling is complete, the nozzle is returned to the pump. At this point, all the relevant data has been exported from the vehicle into the DiaLOG fuel management system. There is no need for any papers to be signed because all refuelling details are automatically stored.

Fuel Inlet Tag

The fuel inlet tag is placed by the fuel tank inlet. The RF nozzle communicates with the fuel inlet tag and fuelling commences. If the two lose signal contact through the nozzle being removed from the vehicle, delivery stops immediately – even if the operator continues pressing the nozzle trigger.

Vehicle Tag

The vehicle tag is a contactless microprocessor that is installed in the vehicle. It identifies the vehicle to the Fuel Management System, providing vehicle data and fuel type, plus engine hour meter readings. Odometer/mileage readings are transmitted automatically by the vehicle tag to the site controller at the time of refuelling.

Radio Frequency Unit

The RFN is a wireless device that slips over the nozzle and identifies the nozzle to the system. It is a robust system that is easy to install and does not require any adaptations to the nozzle. Only when the correct fuel nozzle is inserted in the fuel tank inlet will authorisation be approved and fuel be dispensed into the vehicle.
