Abstract
For measurement of chlorine concentration in a process stream, an improved device is set forth measuring light transmission in a selected frequency range. The preferred embodiment uses a light source, a light filter and an optical fiber extending to a pipe or other vessel with flowing chlorine. The light is transmitted from a lens system to another lens system and into a second optical fiber. The second fiber extends to a measuring device.
