Abstract
A level sensor includes a substrate having at least one reflective side surface, at least one wave generator on one end of the substrate configured to transmit a wave down the surface of the substrate and a plurality of reflective echelons mounted on the substrate such that each echelon is at an angle relative to reflective side surface. The reflective echelons are configured to convert a wave of a first mode in to a wave of a second mode.
