Electroacoustic transducers and systems (often used to measure tank level) are not the same as electronic components

This paper examines the complexity of ultrasonic & sonar sensing devices and challenges the misconception that transducers are a commodity component that anyone is qualified to build, buy, or sell. All transducers are not created equal. Reputable electroacoustic transducers are complex structures that can operate for decades without obsolescence.
