A flow control device includes a flow channel composed of non-magnetic material having a center axis, a first length segment having a first diameter, a second length segment, wherein the flow channel expands conically from the first diameter to a second diameter in the second length segment, and a third length segment; a magnetic closing ball, which is movably arranged in the second and third length segments and has a ball diameter that lies between the first and the second diameters; a first, axially polarized (north-south) ring magnet, which is oriented centrally in the center axis and is arranged so as to be longitudinally movable along the center axis and has an inside diameter that is greater than the outside diameter of the flow channel in the third length segment; and a preloading device, which axially pushes the north-south-polarized first ring magnet toward the first length segment

An apparatus for automated decantation of a multi-phase fluid mixture comprising a decantation container, a floating marker, a sensor, a plurality of engines and a plurality of micro-switches. The decantation container comprises an inlet valve and at-least two outlet valves. The floating marker is housed within the decantation container. The floating marker is of a selective density. The sensor is attached at a bottom surface of the decantation container. The plurality of engines are connected with the sensor. The plurality of engines controls an opening and a closing of the at-least two outlet valves. The plurality of micro-switches are connected to the plurality of engines. The plurality of micro-switches control an amount of power supplied to the plurality of engines.
