摘要： An oil-contaminated water stream is monitored by continuously exciting and measuring fluorescence in the stream at a monitoring point and producing a continuous monitoring indication accordingly, recurrently withdrawing from the stream samples of the contaminated water, determining the oil content of each sample by an infra-red absorption procedure, comparing each oil determination with the monitoring indication pertaining to the appropriate part of the stream and correcting or recalibrating the monitoring indication accordingly.

摘要： An apparatus for detecting the presence in a liquid of material that emits fluorescent radiation when stimulated by ultraviolet radiation. A chamber having an inlet and an outlet for passing a stream of liquid therethrough. A source of ultraviolet radiation associated with said chamber with means for energizing same whereby said radiation may pass to said stream and a receiver arranged to receive fluorescent radiation emitted by such a stream.
摘要翻译： 一种用于检测当由紫外线辐射刺激时发射荧光辐射的材料的液体中的存在的装置。 具有用于使液流通过其中的入口和出口的室。 与所述腔室相关联的紫外线辐射源，具有用于激发相同功能的装置，由此所述辐射可以传递到所述流，接收器布置成接收由这种流发射的荧光辐射。
