Abstract
A fluid level sensor measures a height of a fluid in a volume with a plurality of piezoelectric sensors arranged along at least one wall of a container. The sensors are positioned to enable activated sensors to interact with the materials adjacent the sensors to produce electrical signals in more than one of the sensors. These electrical signals are used to identify the fluid level in the volume.
