Abstract
A system for sensing a fuel level includes sensors that sense the fuel level and a voltage source that applies a constant voltage to the sensors for a predetermined time. The system includes a control module that measures outputs of the sensors at a beginning and at an end of the predetermined time. The control module determines a number of the sensors that are submersed in fuel or air based on the outputs and calculates the fuel level based on the number of the sensors that are submersed in fuel or air.
