Abstract

Known devices for determining the filling level of liquefied gases in a cryogenic container are provided with an array of sensors distributed vertically along the volume to be measured, and with a signal transmitter for producing a signal that can be detected by the sensors, as well as with a level indicator. The aim of the invention is to provide, starting from the prior art, a simple and low-maintenance level meter. To this end, the signal transmitter comprises a magnet (11) linked with a floating body (10). Said magnet can be displaced along an array of magnetic field sensors (5) and produces a magnetic field that is detected depending on the filling level (8) by one or more of the magnetic field sensors (5) and is transmitted to the level indicator (6) in the form of a filling level signal.
