An electrodeless apparatus for determining a function of the electrical charge condition in a flowable liquid media containing electrical charge influencing species comprising a tubular flow path member, the flow path member having electrically insulating walls, an open end and a closed end, the flow path being so disposed that it may be substantially filled with the liquid, a reciprocating member whose outer wall is electrically insulating disposed within the flow path member, the reciprocating member having a transverse cross-sectional configuration such that the reciprocating member fits adjacent but spaced from the electrically insulating walls of the flow path member, an annulus for admitting predetermined amounts of flowable material to the flow path member, a sensor disposed on the non-wetted side of the flow path member for developing a signal proportional to a desired ion activity by electrostatic or inductive coupling, and means coupled to said sensor for amplifying any electrical signal induced across said sensor.

An apparatus for sensing and quantifying without the addition of an externally induced potential the electrical charge condition in a flowable two phased liquid media containing electrical charge influencing species comprising a tubular flow path member, said flow path member having electrically insulating walls, an open end and a closed end, said flow path being so disposed that it may be substantially filled with said liquid, a reciprocating member whose outer wall is electrically insulating disposed within said flow path member for mechanically inducing the ions in said liquid to flow in more than one direction, said reciprocating member having a transverse cross-sectional configuration such that said reciprocating member fits adjacent but spaced from said electrically insulating walls of said flow path member and provides a controlled pressure drop, means for admitting predetermined amounts of flowable material to said flow path member, sensory means disposed on the non-wetted side of said flow path member for solely developing a signal proportional to a desired ion activity by electrostatic or inductive coupling, and means coupled to said sensory means for amplifying any electrical signal induced across said sensory means.
