Abstract

An ultrasonic streaming current detector for developing on a continuous basis, electrical signal which is a function of the charge condition existing in the stream containing charged particles therein, for thereby facilitating the determination of the dosage of floculate to be added to a charge implacing species field stream, for thereby ultimately controlling floculation of such streams. The present invention employs a cross-shaped housing having cross-member and a longitudinal member, a piston receiving member, a reciprocating piston, a pair of electrodes, a meter recorder and a electrical mortar. The piston pumps, the simple stream within its interior and by means of this reciprocating shear force against the simple stream generating an electrical signal across electrodes dispositioned at either end of the pump stroke of the piston to thereby generate an electrical signal through lead wires connected to a meter recorder box. The circuitry of the meter recorder box converts the electrical signal into a routable form which is representative of the average electrical charge of the suspended particles in said simple stream.

Dependent claims

An ultrasonic streaming current detector apparatus for determining a function of a charge condition present in a system containing fluid with charge-influencing species, comprising:

a. a cross-shaped tubular member having cross-member and longitudinal elements adapted to being substantially filled with said fluid;
b. a piston receiving member being longitudinally coaxial with said longitudinal element;
c. a casing substantially surround said piston receiving member;
d. a pair of electrodes, the first electrode being disposed adjacent the bottom end of said piston receiving member and the second electrode being disposed in said piston receiving member above the first electrode;
e. a reciprocating piston element disposed in a central bore of said piston receiving member and said casing;
f. means for reciprocating said reciprocating element within the bore of said piston receiving member, so as to cause said fluid to flow to and from said bore, in a continuous, repetitive manner thereby generating electrical signals across said electrodes;
g. means for amplifying electrical signals generated across said electrodes, and means for utilizing said amplified signals;
h. means for conducting said electrical signals generated across said electrodes from said electrodes to said meams for amplifying said electrical signals and said means for utilizing said amplified signals;
i. means for synchronizing said conduction of said electrical signals with the action of said reciprocating piston element;
j. an ultrasonic cleaning device disposed adjacent to said piston receiving member and said casing for generating mechanical vibrations to prevent agglomeration of said charge-influencing species contained by said liquid in the area about said electrodes.
