Abstract
Abstract A system for monitoring one or more factors relating to the strength of a magnetic field generated by a magnetic force field generator adapted to treat fluid flowing through a conduit. Sensors detect and respond to any change in the factor monitored and actuate means to effect a reversal of such change for maintaining the strength of the magnetic force field to within allowable limits. The system includes a multi-magnet magnetic field generator which generates a plurality of discrete magnet fields of reverse polarity positioned externally of the conduit for saturating the inner area of the conduit for treating fluid flowing through the conduit.
