Patent ID: 7093485

Claim:
Apparatus for sensing the level of fluid within a container comprising: a) a base fixed within the container; b) a movable member supported by the base for relative positioning with respect to said base; c) a float member that moves relative to the base as the level of fluid in a container changes; d) an arm attached to the movable member and float member wherein the position of the float is translated into movement of the moveable member with respect to said base; e) at least one magnetic flux sensor that is housed within a cavity containing encapsulant within the base located within said container and is coupled to one of the moveable member or base for creating an electrical output signal in response to a change in magnetic flux density; and f) at least one magnet disposed proximate the magnetic flux sensor coupled to one of the moveable member or base for providing a magnetic field to induce a change in electrical output response from the magnetic flux sensor as the float member moves with changes in fluid level.
