Flow of fluid from primary and secondary reservoirs is induced along parallel flow paths to a common infusion device under gravity or pump inducing modes, respectively. The fluid delivered to the infusion device is monitored by a flow meter to measure its actual flow rate and adjust flow along the parallel flow paths to maintain a substantially constant selected flow rate by means of a programmed control system through which selection of the flow inducing mode and the reservoir may be effected.

In a flow control system through which fluid is delivered to an outlet conduit, flow metering means for monitoring flow of the fluid delivered to said outlet conduit, a plurality of reservoirs from which the fluid is withdrawn, a fluid displacement pump, flow passage means connected to the reservoirs and the pump for establishing flow of the fluid between the reservoirs and the flow metering through the pump, and in bypass relation thereto and mode control means operatively connected to the flow passage means for selectively conducting the said flow of fluid therethrough alternatively and simultaneously under a gravity head from the reservoirs and from the pump under a positive pressure head to the metering means.
