Fuel Level Sensor Design from a System Perspective

Many of the current issues surrounding the achievement of accurate fuel level indication and fuel sensor design strategy revolve around systems issues, but are most often treated as component deficiencies. This paper takes a “systems” look at liquid fuel level indication as opposed to the traditional “component” view. The intent of the author is to present a framework of system considerations relative to the task of designing a robust fuel level indication system in the automobile.
