Abstract
A liquid level sensor includes a rod having a first portion and a second portion, and a wave generation unit affixed to one end of the rod. The wave generation unit generates a wave group that propagates in at least a shear order and a flexural order, and the frequency of the shear wave is based on the diameter of the rod.
