Abstract
The present system comprises, a MFC controller, emitter-lines that utilize non-drain technology on the emission devices and control valves for individual drip lines or groups of drip lines within an irrigation zone, along with a means to actuate the control valves by the controller. The MCF system utilizes a number of valves in an irrigation system to control either individual emitter-lines or groups of emitter-lines but does not control individual emitters. The present system has a programmable controller that has a number of stations, each of which controls a group of valves. Each station can be programmed for start time and duration that the station is actuated. Each station can be programmed independently from all the others allowing overlap or complimentary irrigation. The total input flow rate to the system remains nearly constant during a daily irrigation while the valve groups are cycling within the system.
