Abstract
The present invention is a fluid level sensing system for determining fluid levels in a fluid container. The system has a resonant member with an attached magnet. The resonant member is disposed in the fluid container. The system also has a sensing device for sensing motion of the magnet. The movement of the magnet attached to the resonant member is indicative of fluid level in the fluid container.
