The manual control of fluid dispensers such as a filling station pump is becoming obsolete. This technology which can only be reset manually, does not also have a provision for the following futures like digital display of amount or converting of the volume in equivalent currency and display of price. There are a lot of errors in counting and it is very difficult to operate.
Due to all this problems an improved technology was introduced as digitally controlled filling station pump meter device.
A filling station pump meter is simply an electronic device calibrated to display the quantity of liquid passed from a storage tank to the fuel tank of vehicles.
Digital control of devices and equipments is the latest technology in most engineering field today. For a device to be controlled digitally there must be a digital electronic circuit interface which communicates the user's ideas to the device.
The project, digitally controlled filling station pump meter is simply one that reads and displays its value in a digital form.
In this project, we employed the tachometer technique to read the quantity of fluid pumped by counting the revolution per minutes of the pumping motor. The value gotten from here is computed by a programmed chip (micro controller) and the final value displayed on the digital display read-out.
The inherent problems of manual control pump meter gave rise to the need for a digitally controlled pump meter because of the follow problems listed below
Fuel pump, fuel flow meter, fuel nozzle, oil pipe, shut off pull values, fuel motherboard, fuel display board, fuel power board, fuel keyboard, explosion-proof motor, thermal printer, mechanical counter, JC card socket, solenoid valve, pulse sensor, flow indicating marker, the body thickness and it can not handle large batches quickly and efficiently.
Finally, the problem of security such as keypad lock/unlock settings features use in preventing accidental or unauthorized changes is not provided in the manual controlled pump meter.
This project report is aimed at knowing the improvement in the digital control pump meter over manual control pump meter, its construction and principle of operation.
This project report is conventionally divided into
Chapter one is the introduction of digitally controlled filling station pump meter.
Chapter two deals with the literature review of the digitally controlled filling station pump meter from the origin to the present digital description.
Chapter three deals with the principle of operation of digitally controlled filling station pump meter.
Chapter four deals with conclusion and recommendation.
