Abstract
An arrangement for, and a method of, treating fluids, e.g., conditioning water in a pipe to resist scale deposits from building up in the pipe, comprise a primary coil mounted exteriorly of the pipe, and an electronic circuit for energizing the primary coil to generate a succession of radio frequency signals that form an electromagnetic field in the water. The field has generally circular flux lines in generally co-axial relation with the pipe, and is propagated along the entire pipe.

In combination with a fluid-carrying conduit extending along an axis, an arrangement for resisting scale formation in the conduit, said arrangement comprising:
- a) a primary coil mountable exteriorly of the conduit;
- b) means for successively energizing the primary coil to generate a plurality of radio frequency signals spaced timewise apart, each radio frequency signal having a variable amplitude diminishing from a maximum value to zero, each radio frequency signal having a frequency in a range from about 200 KHz to about 500 KHz;
- and
- c) means responsive to the generation of the radio frequency signals, for generating in the fluid an electromagnetic field having generally circular flux lines in generally co-axial relation with the axis of the conduit, and for propagating the field along the axis to resist scale formation by the fluid both upstream and downstream of the primary coil.
A method of resisting scale formation by a fluid contained in a conduit extending along an axis, comprising the steps of:
- a) mounting a primary coil exteriorly of the conduit;
- b) successively energizing the primary coil by generating a plurality of radio frequency signals spaced timewise apart, each radio frequency signal having a variable amplitude diminishing from a maximum value to zero, and each radio frequency signal having a frequency in a range from about 200 KHz to about 500 KHz;
- and
- c) generating, in response to the generation of the radio frequency signals, in the fluid an electromagnetic field having generally circular flux lines in generally co-axial relation with the axis of the conduit, and propagating the field along the axis to resist scale formation by the fluid both upstream and downstream of the primary coil.
