Systems and methods of determining a quality and a quantity of a fluid
First Claim
1. A system for determining a quality and a quantity of a fluid in a tank having a bottom, the system comprising:
- a first transducer configured to generate a first sound wave in a horizontal direction and to detect a first echo of the first sound wave;
a second transducer configured to generate a second sound wave in a vertical direction and to detect a second echo of the second sound wave; and
a 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 from the first transducer,receive a second indication of the detected second echo from the second transducer,determine, based on the first indication, whether the detected first echo is valid,determine, based on the second indication, whether the detected second echo is valid,determine, based on the first indication, at least one selected from the group consisting of a quality of the fluid and a concentration of the fluid, when the detected first echo is valid, anddetermine, based on the second indication, at least one selected from the group consisting of a quantity of the fluid and a level of the fluid, when the detected second echo is valid.

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.
