Abstract
A fiberoptic filling level determination apparatus for liquid transparent medium disposed in a container has a light wave conductor that is disposed within the container and has an input section that is connected to a light source and is guided in the container, in a helical path, to the deepest level of the container accessible for the filling level determination. Proceeding from the input section, the light wave conductor has a linear output section that is guided out of the container. Associated with the input section and the output section, externally of the container, is a respective device for measuring the intensity of introduced and exiting light. The ratio of the intensity measured by the devices can be represented in a filling level value.
