Abstract
A fill-level detector operating by the radar principle gauges the fill-level of the lower of two substances layered one atop the other in a container. The detector incorporates first and second essentially straight, parallel electrical conductors having a signal generator and a transducer mounted to the upper ends of the conductors with the lower ends of the conductors protruding into the lower substance. The generator delivers a signal to the first conductor which signal is conducted into the lower substance with a portion of that signal being reflected at the interface of the two substances which signal portion is captured by the transducer. The detector is able to determine to fill level of the lower substance even when the upper substance displays a high dielectric constant.
