Abstract
A device and a method for measuring fluid flow and solute mass transport in flow systems includes a casing (1) having inlet (3) and outlet (9) openings and a fluid passageway therebetween, the 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.
