Patent ID: 8615329

Claim:
A control system for regulating the flow of a liquid from a liquid provider through a liquid distribution system, the liquid distribution system having liquid monitors for sensing a liquid flow characteristic within a major and a plurality of minor distribution channels, the plurality of minor distribution channels connected to a multiplicity of user channels for providing a flow of liquid to each of a multiplicity of users, the liquid provider having a transmitter and receiver connected to the liquid monitors sensing the liquid flow characteristic within the major and the plurality of mirror distribution channels, comprising: an irrigation channel connected to each of said multiplicity of user channels for receiving a flow of a liquid downstream from the user channel; an irrigation system having an irrigation zone connected to each of said irrigation channels; a controllable user valve located in each of said irrigation channels upstream from said irrigation system for controlling the liquid flow from said irrigation channel to said irrigation system; a user transmitter and receiver connected to said controllable valve located in each of said irrigation channels; the liquid provider transmitter and receiver transmitting a first signal to said user transmitter and receiver upon sensing an undesired liquid flow characteristic within one of the major and plurality of minor distribution channels to close said controllable user valves to terminate the flow of liquid to said irrigation system of said multiplicity of users to restore a desired liquid flow characteristic within the major and the plurality of minor distribution channels and the multiplicity of user channels; and said liquid provider transmitter and receiver transmitting a second signal to said user transmitter and receiver upon sensing a desired liquid flow characteristic within the major and plurality of minor distribution channels to cause said controllable user valves to open to cause flow of liquid to said irrigation system of said multiplicity of users to irrigate the landscape of said multiplicity of users by causing a programmable user control connected to the user transmitter and receiver to continue a remainder of a pre-established program irrigation schedule which was cancelled due to the first signal.
