Each of the three or more distribution channels has a respective variable flow control valve and carries a respective portion of the total inlet fluid flow. The hybrid flow ratio controller further includes a controller operatively coupled to the respective variable flow control valves. The controller is configured to control a flow rate of at least a first distribution channel according to a predetermined flow ratio of the inlet fluid flow in accordance with a flow ratio control mode, to control a flow of at least a second distribution channel in either a flow rate control mode or a pressure control mode, and to control a third distribution channel in an overflow mode.
