CONTAINER WITH FLEXIBLE WALLS

A container (2) has flexible walls surrounding a container interior (6). At least one electrical sensor (3, 3′, 3″, 3′″, 3″″) projects into the container interior (6) and has at least first and second electrically conductive plates (8, 8′, 9, 9′, 9′″) for determining the conductivity or impedance of a medium that surrounds the plates (8, 8′, 9, 9′, 9′″). The plates (8, 8′, 9, 9′, 9′″) are connected via connecting lines (10, 11) to a control and regulating unit (4) outside the container interior (6). At least the first plate (8, 8′) is on a closed free end of a sheathing (5, 5′, 5″″) and has a contact area exposed to the surrounding medium. The sheathing (5, 5′, 5″″, 17, 17″″) is a flexible hose (7) or bellows (19, 19″″) through which the electrical connecting line (10, 11) of the plate (8, 8′, 9, 9′, 9′″) is routed.
