Abstract
Apparatuses and methods for fuel level sensing are described herein. An example sensor may include a sealed housing and an electrically conductive coil. The sealed housing may comprise a pivot end, a float end opposite the pivot end, and an interior defined by walls extending therebetween. The pivot end may be adapted to join a pivot point and the float end may be adapted to join to a float at an exterior of the housing. The electrically conductive coil spring is disposed in the housing interior and comprises a first end and a second end opposite the first end. The coil spring is adapted to expand and retract in response to movement of the internal float within the housing and to electrically couple to a circuit configured to sense a change in resistance in the coil spring in response to expansion and retraction of windings of the coil spring.
