Abstract
A device, having a container for holding a fluid moving therein and a conductance probe installed therein for providing a conductance signal indicating whether it is in contact with the fluid, features a jiggler arrangement having a jiggler arranged on the conductance probe so as to form a mechanical self-cleaning conductance probe, which responds to movement of the fluid, for wiping the conductance probe to keep deposits from building up on the conductance probe. The jiggler arrangement may include one or more grooves thereon so that the jiggler can be loosely fitted on the tip between one or more retaining rings arranged in the one or more grooves. The jiggler arrangement may include one or more retaining rings snap-fit on the tip for loosely arranging and retaining the jiggler on the tip.
