Abstract
A method and system for determining the level of fuel contained in the tank of a motor vehicle includes a first resistive element disposed in the tank and having a first predetermined length. The first resistive element generates a variable resistance in response to electrical current and fuel passing therethrough. A second resistive element is also disposed in the tank and has a second predetermined length. The second resistive element generates a fixed resistance in response to the electrical current and fuel passing therethrough. A microprocessor coupled to the first and second resistive elements determines the level of fuel contained in the tank based on the variable resistance, the fixed resistance and the first and second predetermined lengths.
