Abstract
A system for sensing a fluid. The system including a fixed object; a first transducer generating a first sound wave in a horizontal direction and to detect a first echo of the first sound wave from the fixed object; a second transducer generating a second sound wave in a vertical direction; a temperature sensor detecting a temperature of the fluid; and a controller. The controller configured to produce a first signal to drive the first transducer to produce the first sound wave, produce a second signal to drive the second transducer to produce the second sound wave, receive a first indication of the detected first echo, receive a second indication of the detected second echo, receive a temperature indication, determine a quality of the fluid based on the first indication and the temperature indication, and determine a quantity of the fluid based on the second indication.
