ABSTRACT:
A radar level gauge system is disclosed, having a transmitter for transmitting measuring signals towards the surface of the filling material, a receiver for receiving echo signals from said surface and a fastening structure adapted to secure said transmitter and receiver in a measuring position on a feed-through structure located in an upper boundary of said container. Further, a sealing unit is arranged between said fastening structure and said feed-through, and adapted to provide a pressure seal between the inside and the outside of the container, and in addition, there is provided means for blocking electromagnetic energy, adapted to block net transfer of electromagnetic energy between the inside and the outside of the container through said sealing unit.
