ABSTRACT:
A flow controlled irrigation system which automatically stops the flow of water to an area when that area has received a predetermined quantity of water and then redirects the water to another area is disclosed. The system includes an upwardly extending gate member which defines a pair of passages therein. A first of the passages directs water to an area to be irrigated while the second causes the water flow to bypass the area. A flow control member activates the gate member when a predetermined volume of water has flowed through a meter.
