Abstract
A parabolic antenna for measuring the level in containers is proposed, a transmitted pulse from a transmitting and receiving device being focused via the parabolic antenna and directed onto the surface of a filled material whose level is to be determined, and the pulse reflected at the surface of the filled material being received again by the receiving device via the parabolic antenna. For the purpose of introducing the measuring instrument through an opening in the container, the parabolic antenna can be folded and unfolded by being positively moved.
