A liquid level sensing arrangement for a tank may include a float having a disc-like shape and a sensor that detects a position of the float relative to the tank. The float may have an overall height/total displacement ratio of 0.5 or less. The float may have a range of motion relative to the tank so that at least a portion of the float may move below a portion of a bottom wall of the tank and/or below an outlet for the tank.
What is claimed is: 1. A liquid level sensor arrangement for detecting a level of a liquid in a tank, comprising: a tank defining a volume in which a liquid having a top surface is holdable; a structure that defines a chamber including opposed sidewalls that, at least in part, define the chamber; a non-spherical float that is arranged for movement in the chamber relative to the tank and to be positively buoyant in the liquid so as to adjust in position based on changes in location of the top surface of the liquid, the float being arranged to present onl...
