Date Sep. 17, 1992A metallic indicator electrode senses the anionic charge per unit time borne by the dispersed phase of a stream of an aqueous dispersion of negatively charged particles by virtue of the potential developed by the electrode as measured by a voltmeter. The developed potential can be used downstream, for example, to control the addition of a water treatment chemical or extraction of water from the stream.
