Abstract

Technology is described for tank coupled to an ultrasonic sensor subassembly where the combination of the tank and ultrasonic sensor subassembly for an ultrasonic sensor. In an embodiment, ultrasonic sensor subassembly is configured to form an ultrasonic sensor upon coupling to a tank having a tank wall. The ultrasonic sensor subassembly includes a sensor subassembly housing, a planar piezoelectric element located within the sensor subassembly housing, and a circuitry electrically connected to the planar piezoelectric element, where the planar piezoelectric element includes a surface coupled to the tank wall such that the tank wall forms a matching layer of an ultrasonic sensor, and the circuitry configured to produce a signal to drive the planar piezoelectric element to generate a sound wave, and receive an indication of a detected echo from the planar piezoelectric element. Various other methods and systems are also disclosed.
