| 摘要 |
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, 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, 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, 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 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. |
