The invention relates to an apparatus for determining the filling level of a filling material in a container having a signal production unit which produces measurement signals, having at least one antenna which transmits the measurement signals in the direction of the surface of the filling material

The invention relates to an apparatus for determining the filling level of a filling material in a container having a signal production unit which produces measurement signals, having at least one antenna which transmits the measurement signals in the direction of the surface of the filling material and which receives the measurement signals reflected on the surface of the filling material, and having a control/evaluation unit which uses the delay time of the measurement signals to determine the filling level of the filling material in the container. The apparatus allows a filling level measurement device, which operates on the delay-time principle, to be mounted on a container in a cost-effective and simple manner. An opening is provided in the upper region of one sidewall of the container, and in that the at least one antenna is positioned in this opening with the antenna being arranged and configured such that the measurement signals are emitted essentially in the direction of the surface of the filling material and such that the measurement signals reflected on the surface of the filling material are received by the at least one antenna.

A locking device according to claim 16, wherein said device includes a set of at least two sleeve elements having variable inner and outer diameters and configured to be selectively nested within each other, the innermost sleeve element of said nested sleeve elements being sized for close-fitting engagement with said hitch pin shank, said retention element selectively maintaining one or more of said sleeve elements in nested position on said hitch pin shank. 19. A locking device adapted for alternative close-fitted insertion within a first aperture having a first diameter and a second aperture having a second diameter larger than the first diameter, comprising: (A) a shackle member including (1) a cylindrical shank having a shank diameter of a first selected size for mated engagement with the first aperture such that said shank may be inserted into and removed from the first aperture (2) a latch portion located at a first end portion of said shank and (3) a stop portion located at a second end portion of said shank; (B) a locking head configured to selectively engage said latch portion to define a mounted state and movable between a locked state wherein said locking head is lockably secured to said shackle and an unlocked state wherein said locking head is removable from said shackle; (C) a sleeve formed as a cylindrical shell having an inner diameter sized and adapted for close-fitted yet removable telescopic engagement on said shank and a larger, outer diameter of a selected size for close-fitted, mated engagement with the second aperture, said sleeve operative when received on said shank such that said shank and sleeve may be inserted together into and together removed from the second aperture. 20. A locking device according to claim 19 including a retaining element operative to resist removal of said sleeve from said shank when said locking head is in the unlocked state and removed from said latch portion. 21. A locking device adapted for close-fitted, alternative insertion within first and second apertures having different sizes, comprising: (a) a shackle member having a shank portion; (b) a locking head movable between a locked state and an unlocked state; (c) a latch portion disposed at said shank first end portion and configured to selectively engage said locking head; (d) a stop portion disposed at said shank second end portion; and (e) a sleeve carried on said shank such that said shank and said sleeve together provide said shackle with one operative thickness dimension for close-fitted insertion within one of said first and second apertures, said sleeve being removable from said shank such that said shackle has another operative thickness dimension smaller than said one operative thickness dimension for close-fitted insertion within another of said first and second apertures said sleeve operative when received on said shank such that said shank and said sleeve may be
