Patent ID: 6923056

Claim:
A sensing assembly for sensing liquid levels in a reservoir and for creating a sensing signal therefore, said sensing assembly comprising: a first electrical conductor extending into the reservoir; a second electrical conductor extending into the reservoir and disposed from said first electrical conductor a predetermined distance; a first electrode electrically connected to said first electrical conductor, said first electrode extending between a first conductor end and a first distal end and defining a first electrode length therebetween; a second electrode electrically connected to said second electrical conductor, said second electrode spaced apart from said first electrode and extending between a second conductor end and a second distal end defining a second electrode length therebetween, said first electrode disposed at an angle with respect to said second electrode; and a plurality of plates operatively connected to said second electrode spaced equidistantly therealong and extending out from said second electrode toward said first electrode such that each of said plurality of plates is disposed a distance from said first electrode differing from the other of said plurality of plates, each of said plurality of plates combine with said first electrode to create a unique capacitance wherein the sensing signal generated by said sensing assembly determines the level of the liquid in the reservoir.
