Design and development of fuel level measurement technique for automotive application

Abstract

In day to day life use of vehicle is continuously increasing among all the countries, and as a most important part of vehicle, usage of fuel is increasing and not it is becoming critical problem. So, for accurate measurement of fuel level becomes extremely important. The design and development of Capacitive sensor is some contribution towards the accurate fuel level measurement in automotive sector. Wide variety of existing fuel level sensors are available such as mechanical float type, load cell, ultrasonic transreceiver based and Capacitive plate sensors. Nowadays all the vehicle has digital display (Dashboard) units, so fuel bunks occurring chances are more compare to other because of the digit roundoff. When we refill the fuel, we don't know the exact amount of fuel added is same as that to the amount paid by us. So here the fuel level measurement sensor plays vital role for customers, at the same time it improves performance and safety aspects related to the vehicle. Currently the capacitive fuel level measurement sensors are used in Aircrafts, where fuel level is considered as most critical parameter. That implies the capacitive level sensor construction is costly for small vehicle. So, the main objective of this paper to working towards the development of low-cost capacitive fuel measurement sensor for 2W/3W vehicles.
