Abstract
Ferromagnetic tagging material is suspended in a constituent of a two constituent mixing system. Two tagging material sensors are employed that respectively monitor the tagged constituent as it flows in the system alone and the mixed constituents as they flow to a dispenser nozzle. A monitor calculates the volumetric ratio of the two constituents present when mixed based upon the concentration of tagging material sensed by each sensor. A warning is given when the calculated ratio exceeds predetermined limits.
