The present system identifies leaks in irrigation systems by monitoring the overall flow at an irrigation system valve. The system may monitor typical flow rates and may send a signal to shut off an irrigation system valve if an unexpected or excessive flow rate is detected. The present technology can be used in traditional sprinklers, drip irrigation systems, and other irrigation systems.

1. A method for monitoring and controlling water flow in a sprinkler system including a plurality of water pipe branches, the method comprising: monitoring, by a pressure or flow sensor and in real time, water flow through each of the plurality of water pipe branches, wherein each of the plurality of water pipe branches comprises: a pressure or flow sensor; an electronic circuit in communication with the sensor; a manifold for accepting the water flow; a control valve for controlling flow of water to a branch of the sprinkler system;measuring water flow through each of the plurality of water pipe branches for a predetermined period of time, in response to the monitoring;determining a baseline water flow level for each of the plurality of water pipe branches by a respective electronic circuit, in response to water flow measurements through each of the plurality of water pipe branches;estimating a first threshold and a second threshold for each of the plurality of water pipe branches, based on the baseline, water pressure, pipe diameter, water temperature, or a combination thereof in a respective water pipe branch, for each of the plurality of water pipe branches, wherein the first threshold is for triggering an alert and the second threshold is for reducing or stopping water flow in a respective water pipe branch; andadjusting the fluid flow in one or more of the plurality of water pipe branches of the sprinkler system by the electronic circuit by: receiving, by the electronic circuit, a first signal from one or more pressure or flow sensors of one or more of the water pipe branches;determining, by the electronic circuit, whether the water flow in said one or more of the water pipe branches exceeds the baseline by an amount more than the estimated first or second thresholds for said one or more of the water pipe branches, based on the first signal;when the baseline for a particular water pipe branch exceeds the first threshold for said particular water pipe branch, generating, by the electronic circuit, a second signal to a controller to trigger an alert; andwhen the baseline for the particular water pipe branch exceeds the second threshold for said particular water pipe branch, generating, by the electronic circuit, a third signal to the controller valve for said particular water pipe branch to reduce or stop water flow only in said particular water pipe branch. 2. The method of claim 1, wherein the monitoring is implemented using a pressure or flow sensor displaced after a respective control valve in the water flow. 3. The method of claim 1, wherein the monitoring is implemented using a pressure or flow sensor displaced before a respective control valve in the water flow. 4. The method of claim 1, wherein the monitoring is implemented using a pressure or flow sensor displaced inside a respective control valve in the water flow. 5. A system for monitoring and controlling water flow in a sprinkler system including a plurality of water pipe branches, comprising: a pressure or flow sensor in each of the plurality of water pipe branches for measuring water flow through each of the water pipe branches for a predetermined period of time;a circuitry in communication with the each of pressure or flow sensor;a manifold in each of the plurality of water pipe branches for accepting the water flow in each of the plurality of water pipe branches;a control valve in each of the plurality of water pipe branches for controlling flow of water to a respective water pipe branch of the sprinkler system;a controller in communication with the control valve; anda master controller valve installed above a manifold and in communication with the control valve; whereinthe circuitry determines a baseline water flow for each of the plurality of water pipe branches based on data received from a respective pressure or flow sensor, whereinthe circuitry estimates a first threshold and a second threshold for each of the plurality of water pipe branches, based on the baseline, water pressure, pipe diameter, water temperature, or a combination thereof in a respective water pipe branch, for each of the plurality of water pipe branches, wherein the first threshold is for triggering an alert and the second threshold is for reducing or stopping water flow in a respective water pipe branch, whereinthe circuitry receives a first signal from one or more pressure or flow sensors of one or more of the water pipe branches, determines whether the water flow in said one or more of the water pipe branches exceeds the baseline by an amount more than the estimated first or second thresholds for said one or more of the water pipe branches, based on the first signal;when the baseline for a particular water pipe branch exceeds the first threshold for said particular water pipe branch, generates a second signal to trigger an alert, andwhen the baseline for the particular water pipe branch exceeds the second threshold for said particular water pipe branch, generates a third signal to reduce or stop water flow in only said particular water pipe branch,and whereinthe controller is adapted to shut off or adjust water flow to the manifold and separately and independently shut off or adjust the control valve in each of the plurality of water pipe branches. 6. The system of claim 5, wherein the threshold is based on a standard deviation of the baseline. 7. The system of claim 5, wherein each pressure or flow sensor is displaced after a respective control valve in the water flow. 8.
