Abstract
A device for determining the level of UV-transmission through a flowing media This UV-transmission is determined by measuring and evaluating the radiation intensity of a UV-radiation source radiating through a zone of the medium. The emitting surface of the UV-radiation source partly extends into the flowing medium and partly into a reference space, or borders on the medium and the space. Two UV-sensors are directed at zones of equal irradiation intensity of the radiation source emitting surface. In this case, the one UV-sensor is arranged in the flowing medium and the other UV-sensor in the reference space. Both UV-sensors are connected to a measuring and evaluating circuit, which compares and evaluates the signals of the UV-sensors.
