Construction of Digital Fuel Level Indicator

ABSTRACT

              Today in this digitalized world, if the fuel indicator in the automobiles is also made digital it will help to know the exact amount of fuel available in the fuel tank. The above furnished fact is considered in our project and we found out a proper solution for indicating the accurate availability of fuel in the tank digitally. An ultrasonic transmitter and receiver is used to find out the fuel level which is economic and also accurate. The added Feature in this fuel level indicator is that, the reserve condition is pre-informed to the user with an alarm, which helps to tune it to the reserve position before the engine stops and this helps to avoid knocking and engine damage. This seminar mainly concentrates about the indication of fuel level in irregular tanks (two wheeler tanks). Various other features like the distance covered, mileage obtained, can be added with this arrangement which explains the clear performance of the vehicle and the fuel used. We also predicted the time for refueling the vehicle and also to check the amount while fueling. By using this digital fuel level indicator the amount of fuel available in the tank at any position of the vehicle is predicted. The calculation is based on the principle of sonar through which the depth of the vacuum available in the tank is found out and the accurate amount of fuel in the tank is displayed in the scale of liters.

        Knowing the level of fuel in tank or reservoir is very vital especially in cases where failure in fuel supply can be a very disadvantage. This therefore necessitates the construction of electronic which can detect the level of fuel in a tank and display related information. The project fuel level indicator using microprocessor and a segment display is built around a microprocessor chip (INTEL 8051) and other sensory and display devices incorporated. The display in the project is in alphanumeric example L1, L2, L3, and FL. The chapter one of this project is an introduction to fuel level indicator, the chapter two is a literature review, the chapter three deals on project construction methodology while chapter four explain the result analysis. Finally the chapter five is the conclusion and recommendation.
