ABSTRACT:
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.
