Abstract
A system for controlling viscosity of drilling fluid, the system, in certain aspects, including a container of the material, a viscosity sensor in the container for producing viscosity signals, 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 controlling the centrifuge and the pump apparatus in response to viscosity signals so that selected solids from material processed by the centrifuge are removed to control viscosity of drilling fluid material in the container; and in certain aspects, a similar system for controlling density of a drilling fluid material.
