Abstract
A streaming current monitor comprises a cylinder in fluid communication with a flow-path between an inlet and outlet and a piston received in the cylinder. A drive mechanism is configured to drive reciprocation of the piston in the cylinder to move colloid into and out of the cylinder via an annular space between the piston and cylinder. A pair of electrodes are exposed in a wall of the cylinder and spaced apart in a moving direction of the piston to sense a charge characteristic of the colloid. The drive mechanism is a linear actuator comprising a stationary part and a moving part connected to the piston via a shaft.
