The automobile fuel indicator is an automatic detection system, control unit, and many others. Automation is basically system design that adds on to human comfort, provides the outputs without human interaction, and makes the system user-friendly with auto control schemes. Automation is also now playing a wide role in the field of automobile design and providing the vehicle management system with automatic units so the user has a simplicity to use it.

This automobile fuel indicator kit is also concerned with the design of the automatic units to indicate the fuel level digitally in vehicles. However, it can be used anywhere where the liquid level is to be measured. The indicator gauge is placed inside the fluid. As the level of fluid increases, there is a preset mounted on the bent of the gauge and it gets rotated.

According to the rotation of the preset, we can measure the resistance of the present in terms of the analog voltage. This automobile fuel indicator voltage is calibrated according to the physical dimension of the container in which the fluid is placed. The controller read this variation of voltage and the calibrated value as per the variation is calculated to display the fuel level on LCD.
