Malpractices, due to inefficient flow control at fuel dispensers, especially those owned by private companies,
led to the idea of an automated fuel dispenser. Such a dispenser would be activated by means of an intelligent card,
containing information such as the vehicle registration number, driver's name, fuel tank capacity, supplier name,
last recorded odometer reading and the driver's personal 1.0.number (PIN). Access to the system is obtained by keying in
a PIN code. The amount of fuel dispensed is monitored and could be used together with information from the card, to
calculate fuel consumption data for every vehicle. The information accumulated in the memory of the system can be
downloaded via a modem link to a central control point, eliminating the use of logbooks and saving companies a lot of
time and money.

Companies using more thanl5000 litres of fuel per month, over three successive months are entitled to their own
fuel dispensers (pumps). This implies that the company presently benefits in a true reduction of 2 cents for every
litre pumped. The idea of an automatedfuel dispenser system with fuel flow monitoring and access control was=proposed to the School of
Electrical Engineering at the Cape Technikon, by the ENERGY RESEARCH COUNCIL, to curb alleged malpractices.

A fuel dispenser controller (FOC) with the following features is required:
i) The dispenser would be activated by a card access system which provided storing and managing of data reliably and in
complete security.
ii) The driver would be required to type in a personal identification code as well as the odometer reading to
activate the pump.
iii) The dispenser must be equipped with a sensor measuring the fuel flow and together with the old and present odometer
readings, work out the fuel consumption of the vehicle.
iv) When linked to a central computer via a modem link the fuel dispenser controller (FDC) must be able to download all
the information associated with a particular vehicle.Since current fuel logging and usage systems based on log
books are labour intensive, time consuming and open to abuse, the objective of this project is to develop a FDC system that
is efficient and cost effective and that will provide security against misuse.
