There is a real need in many industries for sensors that do not come in contact with the contents of vessels, tanks, and other containers. Such sensors are important because they avoid contamination of very clean or pure substances. Naveen’s invention uses two ultrasonic transducers mounted on opposite sides on the outside of the container. The two sound waves produced combine to produce an interference pattern that are then used to monitor the contents of the container.
