(under subclass 300) Subject matter in which a fluid is magnetically tagged as a net magnetization in a predetermined direction at a tagging station for detection at a known distance downstream at a detection station within a measured time interval.
(1) Note. Magnetically tagged refers to the magnetic resonance of a fluid volume upon passage through a magnetic induction coil.
