Abstract (en)
[origin: WO9967603A1] Light from a light source (2) is conducted through a light conducting element (4) which is partially submerged in a liquid (12). Light escaping from the light conducting element (4) is scattered by the meniscus (14) of the liquid and the scattered light is collected by a lens (6) and focused to form an image at a detector (8). The meniscus appears as a bright band in the image formed at the detector (8) and the position of the band in the image is used to determine the level of the liquid.
