Technical Examples
  1. An ultrasonic filling level sensor (1), has an elongated measuring chamber (2), which is provided with an opening (3) at each of its two ends, wherein a liquid has the same filling level as outside the measuring chamber (2). The sensor includes an ultrasonic transceiver (6), which is associated with one end of the measuring chamber (2) and the emitted sound signals of which are reflected at the surface of the liquid and at a calibrating reflector (5) and received by the ultrasonic transceiver (6), in order to determine the filling level from the relationship between the transit times of the two signals. It is provided that the cross-section of the measuring chamber (2) and the nature of a wall of the measuring chamber are made to suit the properties of the liquid in such a way that, even in a tilted position of the measuring chamber (2), the surface of the liquid forms a meniscus (14) which forms a reflection portion directed toward the ultrasonic transceiver (6).
