Show moreA flow direction collar is positionable in an electrical zone sensing apparatus with an elongated bore therein disposed in substantial alignment with an aperture through which particles carried by a liquid pass while being electrically sensed. The collar is positioned immediately upstream of the aperture to cause a directional flow of the liquid along a path substantially parallel to a longitudinal axis for the aperture. The flow through the collar directs the particles to flow along paths substantially parallel to the aperture axis thereby reducing the turbulence about the particle created by abrupt changes in velocity. Preferably, the collar includes a housing for telescoping on the bottom of a detection tube.
