Apparatus for optically monitoring parameter of aqueous liquid, has control- and evaluation device for programmable control of pump- and valve unit and is configured to evaluate readings determined by optical measuring arrangement

摘要

The apparatus (100) has an optical measuring arrangement with one and another optical sensors, where one optical sensor has a light source emitting ultra-violet light, a photodetector and a measurement path extending between the light source and the photodetector. A pumping unit passes the fluid and cleaning fluid through a measuring chamber (121). A control- and evaluation device (112) is provided for programmable control of a pump- and valve unit and is configured to evaluate the readings determined by the optical measuring arrangement. An independent claim is included for a method for monitoring parameters of an aqueous liquid, particularly waste water.
