Abstract

A tubing set adapted for use with an apparatus for determining a degree of recirculation flow in a zone of a vessel into which a first fluid having a first electrical conductivity is being inserted and from which a second fluid having a second electrical conductivity is simultaneously being withdrawn. The tubing set comprises a first conduit adapted to convey the first fluid with the first electrical conductivity before it is inserted into the zone of the vessel, said first conduit comprising a first conductivity cell with a first conductivity cell upstream connection, a first conductivity cell downstream connection, and two branches connecting the upstream connection to the downstream connection with a continuous path configuration from the upstream connection to the downstream connection through one of the two branches and returning to the upstream connection through the other one of the two branches, the upstream connection being connectable to a source of the first fluid; and a second conduit adapted to convey the second fluid with the second electrical conductivity after it is withdrawn from the zone of the vessel, said second conduit comprising a second conductivity cell with a second conductivity cell upstream connection, a second conductivity cell downstream connection, and two branches connecting the upstream connection to the downstream connection with a continuous path configuration from the upstream connection to the downstream connection through one of the two branches and returning to the upstream connection through the other one of the two branches, the downstream connection being connectable to a destination of the second fluid.
