Abstract: A matrix controlled device having a reservoir having sidewalls and a bottom, and a plurality of conduits positioned in the reservoir and extending through the bottom thereof. Each conduit has an upper opening, a bottom outlet and an optional sidewall opening at a level intermediate the upper level and bottom of the reservoir and the bottom outlet. A flow control matrix plug is positioned in each conduit at a level between the sidewall opening or upper opening, and the bottom outlet. The flow control matrix plug has an internal passageway size which determines the rate at which liquid flows through the plug. By varying the pore density, pore size, dead volume, length, and elevation of the matrix, delay of the flow rate and initial flow of liquid from the respective conduit can be controlled. The size of an upper opening can be reduced to control air flow rates therethrough, and the size and elevation of a sidewall openings can be selected to control liquid flow rates therethrough.
