Zusammenfassung:	PROBLEM TO BE SOLVED: To provide sensing systems that enable liquid sensing in small and irregular shape reservoirs and that can detect liquids with varying properties.SOLUTION: A liquid level sensor measures a height of a liquid level 168 in a volume with a plurality of piezoelectric sensors 206, 210 arranged along at least one wall of a container. The sensors are positioned to enable activated sensors to interact with materials adjacent to the sensors to produce electrical signals in one or more of the sensors. These electrical signals are used to identify the liquid level in the volume.
