Abstract
A passive device particularly for the improved measurement of the flow of a liquid is described. The device comprises a conduit defining a flow volume for the internal transit therethrough of a liquid to be received at one open end thereof and discharged from the other open end thereof; means disposed in communication with the interior of the conduit for introducing a preselected tracer substance into liquid flowing (full channel flow) through the flow volume; at least one enclosure having wall area permeable to the preselected tracer substance, this enclosure being disposed relative to the flow volume so that the liquid flow through the flow volume will contact the permeable wall area, and means disposed within the enclosure for detecting the presence of such preselected tracer substance as may enter the enclosure through the permeable wall area from the interior of the conduit.
