Patent DE-4117243-A1 (DE)
Inventor: HALLAS ERNST DR RER NAT
IPC: G01N21/05
Filed: 1991-05-27
Abstract: The invention relates to a device for the detection of hydrocarbons, especially oil, in water-conveying pipework systems by determining the transmission behaviour of a light ray. According to the invention, a tubular measuring device is introduced into an existing pipeline system. Said measuring device comprises an internally metallised tubular part with a transparent window at its first end. Mounted on said window is a light emitter, an optical device and a photodetector. Furthermore, the photodetector is connected to an evaluation unit. In addition to the sealed tubular part, the tubular measuring device comprises, at the second end, a tubular part which is internally lined with retroreflecting foil. The light ray emitted by the light emitter enters the water-conveying tube at an angle determined by the arrangement of the light emitter and is repeatedly reflected by the metallised tubular part until it reaches the tubular part lined with retroreflective foil. The light ray is reflected back in the direction of incidence by the retroreflective foil. The returning light ray finally reaches the entry window again, is focused by an optical arrangement, in the simplest case a convergent lens, and is directed onto the photodetector. During its transmission, the intensity of the light ray drops as a result of absorption. If the water contains dissolved hydrocarbons, the component of the light intensity lost by absorption increases. This loss is detected by the evaluation unit. <IMAGE>
