A device and a method for measuring fluid flow and solute mass transport in flow systems comprising a casing (1) having inlet (3) and outlet (9) openings and a fluid passageway therebetween, said casing containing at least one fluid permeable insoluble adsorbent matrix (7) and at least one tracer material (5, 5') located in the fluid passageway. The tracer material (5,5') is a fluid permeable partially soluble material which at least prior to installation is not physically or chemically bonded to the adsorbent matrix (7) and is either mixed with the adsorbent matrix or is located in at least one section (4,4') of the casing (1) separate from but in contact with at least one section (6,6') of the casing holding the insoluble adsorbent matrix (7,7'). The device is intended to be installed in a medium having a fluid path therein.
L'invention concerne un dispositif et un procédé de mesure de débit fluidique et de transport de masse en solution dans des systèmes d'écoulement comprenant un caisson (1) ayant une admission (3) et une sortie (9) avec un passage fluidique entre les deux, ledit caisson contenant au moins une matrice (7) adsorbante insoluble perméable au fluide et au moins un matériau traceur (5, 5') placé dans le passage fluidique. Le matériau traceur (5, 5') est un matériau partiellement soluble perméable au fluide qui, du moins préalablement à l'installation, n'est pas lié physiquement ou chimiquement à la matrice adsorbante (7) et qui est soit mélangé à la matrice adsorbante, soit placé dans au moins une section (4, 4') du caisson (1) séparée d'au moins une section (6, 6') dudit caisson retenant la matrice (7, 7') adsorbante insoluble, mais en contact avec elle. Ledit dispositif est conçu pour être installé dans un support renfermant un chemin fluidique.
