Description
The fuel gauge in automobiles measures the amount of fuel in the tank through the
sensing unit located in the tank and the analog indicator on the dashboard of the vehicle shows
the quantity of fuel per time. This work is designed to ensure the display of the exact volume of
fuel in the vehicle in digital form instead of the usual analog fuel indicator. It will also help to
prevent inaccurate measurement of fuel at the filling station by showing the quantity of fuel
during refuelling. So, a digital fuel gauge system has been designed and constructed to measure
the exact quantity of fuel in the tank and display this measured quantity digitally in litres, by
making use of an ultrasonic sensor and programmable microcontroller and the result obtain is
±0.96% accurate.
