The TTCU allows full fuel management for customers who need refuel in remote locations.


It's a mobile station controller system for the identification of vehicles which controls the refuel made by tank truck, reducing the potential risk for fuel diversion and refueling with wrong type of fuel.






• Controls and optimizes the fleet supply in remote places like: Distilleries, airports, harvests, ports, public works and so on.


• Reduces the time of supply process, through automatic data collection.


• The tank truck, will refuel only vehicles equipped with the VIU ​​- Vehicle Identification Unit.


Control data, odometer and hours worked with complete accuracy.


• In refuel process, the truck tank is able to:


- Collect information such as odometer reading, engine hours and additional information

- Determine the type and amount of fuel to supply;

- Register information of refuel;

- Transferring data to the central computer.

For this application, the controller unit (which is usually installed at the fixed fuel station) has been miniaturized and modified for installation on a tank truck. The controller is connected to the fuel nozzle and controls the electric valve of the tank, responsible for the release of fuel. The equipment is positively identified by the VIU ​​(Vehicle Identification Unit) installed in the vehicle. The controller is now able to record the amount of fuel discharged from the tank truck as well as dispense the correct amount of fuel for a respective vehicle.


The operating system is based on the use of the following:


• Controller Unit - Installed on board the tanker;


Data Terminal Controller (for downloading information) - installed in the central supply station;


Viro Receiver Kit - Installed in fuel nozzle;


Box Relay - A relay box provides electrical current to operate the valve;


Other components of the system for which the installer has the responsibility:


- Communication cable, connecting the tank and controller data. The cable is protected by an external conduit.


- Connection to the solenoid valves and pulsers.


The TTCU can supply simultaneously two vehicles, with two ends nozzle distributors. the number of nozzles can be increased up to four units.


Information processing


The information stored in TTCU are discharged through the connection with the terminal data controller for transferring information to a PC for further processing and reporting. The download is performed by connecting a cable between the controller and the terminal TTCU data. Data collection can also be accomplished through additional GPRS devices. A data terminal can handle several tanker trucks simultaneously.


Processo de Instalação


The vehicle unit:


• A microprocessor called vehicle information unit (VIU) is installed along with DataPass, which connected to the vehicle data bus, extracts data from the odometer, engine hours and additional information.


• The VIU is connected to an antenna (FuelOpass) that is installed in fuel tank inlet. The antenna facilitates communication by radio frequency (RFID) to the receiver installed in the pump nozzle, assuring accurate and authorized data transfer during fueling.


The fuel station unit:


• The fueling station must be equipped with a controller unit (TTCU - Tank Truck Controller Unit) within the tank truck to enable electronic communication between it and the vehicle. To this end, the tank truck nozzle are equipped with a receiving antenna connected to TTCU to communicate with the vehicle VIU.


Automatic fueling:


• When the nozzle of the tank truck is introduced into the tank inlet of the vehicle, communication between the station controller unit and the vehicle occurs in less than one second to allow the refuel, TTCU will check if the vehicle is allowed to refuel through black/white lists, taken from the central computer. Furthermore, the system will check whether the correct type of fuel has been selected;


Upon approval, the controller will allow the fuel to be dispensed;


If the nozzle is removed from the tank inlet of the vehicle, the fuel flow will stop automatically;

At the end of the process, the station controller will register vehicle and fueling information and generate detailed reports of fuel consumption. The fleet manager can customize the reports according to your needs.

The VIU is an electronic component extremely durable, whose relative time between failures (MTBF) is 38 years. This implies that can be reprogrammed and reused.
