Abstract
A streaming current detector has a reciprocating piston with a sensing region having a uniform clearance from the casing which is sufficiently large to avoid significant shearing of the particles in the fluid of the sample stream. A separate guiding region of the piston has a sufficiently tight fit in the casing for smooth reciprocation. A relief region of the piston has the largest clearance from the casing to provide a sufficiently large area to control a constant low velocity of the sample fluid.
