Abstract
An optical level sensor mounted to a ceiling of a tank includes a sensor tube. The sensor tube is provided with support and guidance elements extending with at least three radially distributed positions inside the tank. The support and guidance elements collect, support, and guide optical fibers to different heights of the tank. Each optical fiber has a number of input sides and a number of turns forming sensor heads between two input sides, for a different level. The corresponding support and guidance element bends the fiber in the turns forming sensor heads of a small radius r around at least one corresponding guideway.
