Abstract
A three-mode ultrasonic sensor for determining temperature, level, and/or concentration of a fluid. In one embodiment, the sensor includes a target positioned at a level; a controller, and a transducer electrically connected to the controller. The controller is configured to generate an ultrasonic signal, to receive a reflection of the ultrasonic signal from at least one of the target and a surface of a fluid, and generate a signal based on the reflection. The controller is further configured to receive the signal, and determine whether a level of the surface of the fluid is one of the following group: above the level of the target, below the level of the target, and substantially the same as the level of the target.
