Abstract
L'invention concerne un dispositif destiné à mesurer des caractéristiques de matières fluides en écoulement. Il comporte un tronçon de conduite avec une fenêtre optique. Un cylindre réfléchissant est placé à l'intérieur du tronçon de manière que sa surface extérieure soit voisine de la fenêtre. Un appareil optique émet un faisceau de mesure vers la fenêtre et détecte l'énergie lumineuse réfléchie ou diffusée. Un dispositif peut être prévu pour régler la distance entre la fenêtre et la surface réflechissante du cylindre. L'invention s'applique notamment à la mesure de la teneur en humidité de fluides organiques.A device for measuring characteristics of flowing fluids is disclosed. It has a pipe section with an optical window. A reflecting cylinder is placed inside the section so that its outer surface is close to the window. An optical device emits a measuring beam towards the window and detects reflected or scattered light energy. A device may be provided for adjusting the distance between the window and the reflecting surface of the cylinder. The invention applies in particular to the measurement of the moisture content of organic fluids.
