Abstract
An apparatus for controlling the level of liquid in a centrifugal separator drum by regulating the flow of liquid out of the drum. The drum includes a plurality of circumferentially spaced openings in a radial end wall of the drum. The openings have movable weir plates in one form controlling the openings with the weir plates movable and positionable in a radial direction by axially movable linkage. In another form, a conduit passage leads from an end opening. By controlling the flow through the openings in the end wall, the liquid level is functionally controlled within the drum. The control mechanisms are situated externally of the drum for ease of repair and to provide control which can be continually monitored.
