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.
