Claim Text:
1. A capacitive fluid level sensor assembly for sensing a level of a fluid within a vessel, the sensor assembly comprising: a substrate configured to be positioned alongside a wall of the vessel, such that the wall separates the substrate from the fluid, the substrate having upper and lower ends; and a plurality of conductive members supported by the substrate, the plurality of conductive members being provided between the upper and lower ends of the substrate, wherein the plurality of conductive members includes an upper end conductive member which is most proximate to the upper end of the substrate, a lower end conductive member which is most proximate to the lower end of the substrate, and at least one included conductive member which is positioned between the upper and lower end conductive members, wherein each conductive member is separated from an adjacent conductive member by an intervening space, thereby providing that each conductive member has distinct upper and lower ends and acts as an independent sensor which has a given measurement tolerance between the distinct upper and lower ends, wherein the distinct lower end of a lowermost included conductive member is positioned closer to the lower end of the substrate than the distinct upper end of the lower end conductive member.
