A device for gauging the level of a fluid in a container is described. It comprises a transmitter for transmitting a polarizable microwave signal through a first waveguide section, a receiver for receiving a reflected microwave signal, an electronic unit for determining the reflex position of the reflected microwave signal and an antenna means with a second waveguide section. The device is primarily characterized in that the transmitter and receiver, respectively, transmits a waveguide mode each, mutually orthogonal, and by an easily replaceable third waveguide section inserted between the first and second waveguide sections, provided with means for polarization and/or damping for optimal adaptation of the device to various containers and antennae.
