Abstract
A level sensor includes a first transducer generating a first signal, a second transducer generating a second signal, and a processor configured to switch operation between a first mode and a second mode. In the first mode, the first transducer generates the first signal and the second transducer senses a reflection of the first signal from a surface. In the second mode, the second transducer generates the second signal and the first transducer senses a reflection of the second signal from a reference target. The processor determines a distance to the surface.
