Abstract: A method and apparatus for determining the concentration of a constituent in a fluid by directing a beam of light into the fluid and sensing the intensity of components of the light emerging from the fluid at various wavelengths. The light emerging from the fluid can be light that has been attenuated by absorption or induced by fluorescent radiation. The effect of scattering on the light is minimized by normalizing the component intensities, which are then applied to an algorithm incorporating weighting factors that weighs the influence that the intensity at each wavelength has on the determination of the concentration of the constituent for which the algorithm was developed. The algorithm is developed by a regression analysis based upon a plurality of known mixtures containing various concentrations of the constituent of interest.

Abstract: A device is useful for determining the composition of fluids, in particular the constituents of exhaust gases of internal combustion engines. A light beam (32, 31) passes through the waste gas along the length of a measurement section (29) and becomes more or less weakened or modified in function of the content of the constituents. The light signal received is advantageously recorded by a measurement section light sensor (18), which is shielded from the light source (14) that emits the light, and is evaluated in relation to the original light emission in an evaluation circuit (26). The device lends itself to simple and accurate determination of the turbidity of the waste gas or of the content of optically active constituents in a fluid or gas.

Abstract: Devices are known for determining the concentration of at least one gas in a sample gas stream, having an analysis chamber (10) into which the sample gas stream and a reaction gas stream can be introduced, a detector (48) which measures the optical radiation emitted by the reaction, and a connecting channel (22) via which the analysis chamber (10) is connected to the detector (48). In order to increase the efficiency and measuring accuracy of these devices and to avoid deposits on the walls of the analysis chamber (10) the invention proposes forming the connecting channel (22) as a light conductor (26) which extends from the analysis chamber (10) to the detector (48).

Abstract: The invention relates to a pipe system comprising a pipe, a gas sensing station and a remote output system. The pipe comprises a pipe gas cavity, such as an annulus, extending lengthwise in part or all of the length of the pipe; the gas sensing station comprises a sensing gas cavity which is in gas communication with the pipe gas cavity: The sensing gas cavity comprises a photoacoustic spectroscope. The pipe system comprises at least one optical feeding fiber for feeding light to the photoacoustic spectroscope and a transmission path for transferring a signal from the photoacoustic spectroscope to the remote output system, the transmission path from the gas sensing station to the remote output system is an optical transmission path. The pipe may for example be a flexible pipe e.g. an umbilical or a pipe for the transportation of crude oil from a well to an off shore or on shore station, for example a ship or a platform. The gas sensing station may be integrated in the pipe, e.g. in an end fitting or it may be an external gas sensing station. According to a high security embodiment of the invention it is desired that all energy transported between the remote output system and the gas sensing station is in the form of optical energy e.g. transported in one or more optical fibers. This embodiment provides a very safe and simultaneously well functioning system, with reduced risk of igniting burnable fluids and simultaneously with a high signal-to-noise quality.
