Monitoring system for detecting leaks using a system of flow rate sensors and smart valves

A system comprising:

• a valve configured to adjust an operational state to control a fluid flow rate through a pipe branch of a piping system of a property;
• one or more processors;
• and
• one or more storage devices, the one or more storage devices storing instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
• determining, by the one or more processors and for the valve configured to adjust an operational state to control a fluid flow rate through a pipe branch of a piping system of a property, the operational state of the valve, wherein the one or more processors are configured to, in response to determining that fluid is likely leaking from the pipe branch, transmit an instruction that causes the valve to adjust the operational state to prevent fluid flow through the pipe branch;
• determining, using the operational state of the valve, an expected fluid flow rate through the pipe branch;
• obtaining flow rate sensor data that indicates a measured fluid flow rate through the pipe branch;
• in response to determining that a difference between the expected fluid flow rate through the pipe branch and the measured fluid flow rate through the pipe branch does not satisfy a threshold difference, determining that fluid is not likely leaking from the pipe branch;
• and
• in response to determining that fluid is not likely leaking from the pipe branch, performing one or more automated actions that are different actions than would be performed in response to a determination that fluid is likely leaking from the pipe branch.

A non-transitory computer-readable medium storing software comprising instructions executable by one or more computers which, upon such execution, cause the one or more computers to perform operations comprising:

• determining, by the one or more computers and for a valve configured to adjust an operational state to control a fluid flow rate through a pipe branch of a piping system of a property, the operational state of the valve, wherein the one or more computers are configured to, in response to determining that fluid is likely leaking from the pipe branch, transmit an instruction that causes the valve to adjust the operational state to prevent fluid flow through the pipe branch;
• determining, using the operational state of the valve, an expected fluid flow rate through the pipe branch;
• obtaining flow rate sensor data that indicates a measured fluid flow rate through the pipe branch;
• in response to determining that a difference between the expected fluid flow rate through the pipe branch and the measured fluid flow rate through the pipe branch does not satisfy a threshold difference, determining that fluid is not likely leaking from the pipe branch;
• and
• in response to determining that fluid is not likely leaking from the pipe branch, performing one or more automated actions that are different actions than would be performed in response to a determination that fluid is likely leaking from the pipe branch.
