Abstract: Systems, separators and methods separate one or more solids from a fluid and utilize an automated pressure differential device to improve separation of the one or more solids and the fluid. The systems and methods comprise at least a pressure differential system adjacent a screen in a shaker for separating one or more solids from a fluid, the pressure differential system adapted to provide a pressure differential adjacent the screen in the shaker, a monitoring tool coupled to an actuated arm adjacent the shaker, the monitoring tool adapted to monitor the one or more solids and the fluid adjacent the screen in the shaker, and a controller in electrical communication with the pressure differential system, the monitoring tool and the actuated arm, wherein the controller adapted to control the pressure differential based on the monitoring of the one or more solids and the fluid adjacent the screen of the shaker.
