Optical monitoring processes and apparatus for combined liquid level sensing and quality control |
摘要 |
An apparatus of measuring both concentration and amount of a liquid in a liquid chemical container is presented, comprising viewing light emanating from a first optical member that is in visual contact with the liquid, the light emanating from the optical member having a level indicating quality; and routing light from a second optical member that is in visual contact with the liquid to means for optical discrimination between liquid chemical based on different optical properties.
