Abstract
A system for controlling a centrifuge processing drilling fluid, the system, in certain aspects, including a container of the material, a sensor in the container for producing signals indicative of a fluid density parameter, a centrifuge for removing solids from the material, drive apparatuses for driving a rotatable bowl and a rotatable conveyor of the centrifuge, pump apparatus for pumping material, drive apparatus for the pump apparatus, and a control system for receiving the signals and controlling the centrifuge in response to the density parameter of the drilling fluid.
