Water flow monitoring and leak detection/mitigation system and method
A flow monitoring system, which is configured to detect a leak in a water distribution system having appliances, includes a flow sensor. The flow sensor is configured to detect flow data of a flow of water within a conduit configured to fluidly couple to the appliances. The flow monitoring system also includes a processor. The processor is configured to receive the flow data from the flow sensor, determine whether a reference flow pattern (of a plurality of reference flow patterns) is present in the flow data (where the plurality of reference flow patterns correspond with expected water flow patterns to one or more appliance of the appliances), and initiate a shut-down mode configured to stop the flow of water in response to a determination that the reference flow pattern is not present in the flow data.
1. A method of monitoring a flow of water in a water distribution system having a plurality of appliances, the method comprising:
detecting, via a sensor, flow data of the flow of water toward the plurality of appliances;
determining, via a processor, whether a reference flow signature of a plurality of reference flow signatures is present in the flow data, wherein the plurality of reference flow signatures correspond to expected flows to one or more appliances of the plurality of appliances, and wherein the reference flow signature corresponds to an expected flow to two or more appliances of the plurality of appliances;
sending, via the processor and in response at least in part to a determination that the reference flow signature is not present in the flow data, a notification of a leak condition to a computing device;
receiving, via the processor and from the computing device, a user-bypass instruction; and
bypassing, via the processor, a shut-down mode in response to receiving the user-bypass instruction.
2. The method of claim 1 , comprising:
first determining whether the flow data exceeds a threshold limit parameter; and
then when the flow data exceeds the threshold limit parameter, determining whether the reference flow signature of the plurality of reference flow signatures is present in the flow data.
3. The method of claim 2 , wherein the threshold limit parameter comprises a duration of flow, a max flow volume, or a max flow rate.
4. The method of claim 1 , wherein the flow data comprises a flow rate, a mass flow rate, or a flow flux of the flow of water with respect to time.
5. The method of claim 1 , comprising determining, via the processor, that an additional reference flow signature of the plurality of reference flow signatures is not present in the flow data before determining whether the reference flow signature is present in the flow data.
