Centrifuge control system
 A system, method and computer program for controlling a centrifuge which receives a mixture of liquid and solid particles and separates the liquid from the solid particles. A bowl, along with a conveyor extending inside the bowl, are rotated at different speeds and the speed of, and the torque applied to, the bowl and the conveyor are detected and corresponding output signals are generated. A meter is provided for metering the flow of the mixture to the centrifuge and generating corresponding output signals. A computer responds to instructions from computer programs and controls the speed of the bowl and the conveyor as well as the flow of the mixture and a diluting agent to the centrifuge in response to the output signals in a manner to attain predetermined predetermined optimum operating conditions of the centrifuge.
