Abstract

A vessel (1) has a top opening (2) through which an antenna reflector with multiple segments (3) may be inserted through guide section (4) with the purpose of measuring the level of fluid. The segments are mounted on rotary links (8) and are folded flat during the assembly operation. The links are mounted on a cylinder (7) and are central actuator (9) can be axially displaced to operate on the links to cause each of the antenna segments to swing out radially to the operational position.
