How does it work?


The nozzle is inserted in the fuel tank. The vehicle tag details are validated by DiaLOG vehicle authorisation process.


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


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 to sign any paper because all refuelling details are automatically stored.

Reduce fraud and improve fuel management

AviGO requires “the right amount of the right type of fuel in the right tank”. There is no possibility of filling up another vehicle or a jerry can.


Fuel inlet tag

The fuel inlet tag is placed at the fuel tank inlet. The RF nozzle communicates with the fuel inlet tag and fuelling commences. If the two lose signal contact through the removal of the nozzle from the vehicle, the delivery stops immediately – even if the operator continues to press the nozzle trigger.

Radio frequency unit (RFN)

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 the authorization be approved and fuel dispensed into the vehicle.

Wireless controller

A programmable base station to relay data picked up by nozzle or vehicle units to the FMS and activate/deactivate fuel dispersion based on FMS authorization.

Driver tags

ProFleet’s hand-held driver tag is a “microprocessor-based smart card” that the fleet driver can present at the pump for driver identification. It can only be used in conjunction with the vehicle tag. The driver tag does not contain any method of payment and is for driver identification only; offering an enhanced level of security.
