ABSTRACT:
The detector is a foldable one constructed of unit elements 1a-1n connected with each other through hinge members 6. The members 6 are staggered in arrangement along the longitudinal direction of the unfolded or stretched detector so as to permit the detector to be folded in staggered manner. In storage and transport, the detector is folded to facilitate its handling. In installation, the detector is unfolded or stretched to assume a long-reach form to facilitate its installation in a liquid-level gauge system of a storage tank 13.
