Abstract
Device for measuring a fill level of a container by means of a measuring sensor which is vertically adjustable contingent upon a surface level of liquid in the container, and which is connected to a travel-distance pickup, includes a source of compressed air directed towards the surface level and acting upon the measuring sensor so as to hold a lower end of the measuring sensor suspended at a defined distance above the surface level.
