Described and shown is a method for determining the fill level of a medium, wherein a transmission signal is transmitted, a received signal is received, and the received signal is evaluated in view of the process variable. The method provides that the transmission signal with adjustable transmission signal characteristics is transmitted in such a manner and/or that the received signal with adjustable receiving characteristics is received in such a manner and/or that the received signal and/or a signal derived from the received signal is evaluated using adjustable evaluation criteria in such a manner that the received signal and/or the signal derived from it are filtered into at least one sub- signal. Furthermore, the invention relates to a device for determining the fill level of a medium.

Described and shown is a measuring device (1) with a housing (2) and two electronic devices (3, 4). The measuring device has at least one encapsulated contact element (5) that is designed separately from the electronic units (3, 4) and the housing (2) and is arranged between the two electronic units (3, 4). Furthermore, the contact element (5) has at least one electronic transmission element (6) for creating an electric connection between the two electronic units (3, 4). Advantages of the invention may include providing a measuring device whose electronics are modular, enabling easy adaptation to self-protection.

Shown and described is a float (1) for displaying the fill level of a medium (3) in a container (2), wherein the float (1), in the intended use, is guided from the wall of the container (2, 4) and is suitable for reflecting electromagnetic waves emitted from a transmitter (5) toward a receiver (6). A float that has improved reflecting characteristics of the electromagnetic waves regardless of whether or not the float is tilted is implemented in that, in the intended use, at least the side of the float (1) facing the transmitter (5) is designed as a reflector (20) for reflecting electromagnetic waves to the receiver (6) and that a field attenuation structure (8) is designed behind the reflector (20) from the perspective of the transmitter (5) in such a manner that the electromagnetic wave interacting with the field attenuation structure (8) is attenuated.
