The present disclosure relates to a fastening device for fixing a radar-based fill level gauge to an outer grating of an intermediate bulk container tank. The device comprises a clamping retainer, which can be clamped to a grating bar of the outer grating, and an adapter having a first fastener configured such that the fill level gauge can be mounted detachably on the adapter. The adapter also includes a cut-out, through which radar signals of the fill level gauge can be sent towards the filling material when in the mounted state. In addition, the device comprises a second fastener configured such that the fill level gauge can be fastened indirectly to the clamping retainer. According to the present disclosure, the outer grating is used to fasten the fill level gauge to the container.
