Systems and methods of determining a quality and/or depth of diesel exhaust fluid

Номер: US20120118059A1
Автор: Gregory P. Murphy, Lawrence B. Reimer
Принадлежит: SSI Technologies LLC

A system for determining a quality and/or depth of a fluid in a tank. The system includes a controller, one or more transducers, and a temperature sensor. A fixed distance transducer transmits a sound wave toward a fixed surface. A depth transducer transmits a sound wave which reflects off a surface of the fluid. The temperature sensor senses a temperature of the fluid in the tank and provides an indication of the temperature to the controller. The controller measures the elapsed time for the sound waves to travel between the fixed distance transducer and a fixed surface and the elapsed time for the sound waves to travel between the depth transducer and the surface of the fluid held within the container. Using the elapsed times and the temperature of the fluid, the controller is able to determine a quality and the depth of the fluid.
