The present invention provides a system for regulating fluid flow made up of a solenoid valve interposed on a fluid supply line; a light switch that controls a light; a transformer with a primary side and a secondary side, wherein the primary side is placed in intermediate electrical communication with the light switch and the light, wherein the secondary side is in electrical communication with the solenoid valve, and wherein the solenoid valve allows flow through the fluid supply line when the light switch is activated and prevents flow through the fluid supply line when the light switch is deactivated.

A system for forecasting leaks in a fluid-delivery pipeline network. The system identifies a subsystem in the pipeline network that comprises a plurality of topologically connected stations. The system accesses historical temporal sensor measurements of a plurality of variables of the stations that are directly connected and generates a temporal causal dependency model for a first control variable at the first station in the subsystem, based on the plurality of time series of sensor measurements of a second variable of the first station, and temporal delay characteristics of the plurality of time series of sensor measurements of the second variable at the stations directly connected to the first station. The system automatically calculates a normal operating value of the first control variable at the first station and the deviations between actual measured values and the normal operating value and determines a threshold deviation that indicates a leak event.

A delayed shutoff device comprises a conduit configured to allow a fluid to flow through, wherein the conduit includes a conduit start and a conduit end. The device further comprises a plug configured to be placed inside the conduit at the conduit start; move inside the conduit from the conduit start toward the conduit end when the fluid flows through the conduit; and reduce the fluid flow upon reaching the conduit end. The device is configured to allow a pass-through quantity of the fluid to pass through the conduit while the plug moves from the conduit start to the conduit end. The conduit end may form a seat, the plug being configured to stop moving upon reaching the seat. The plug may be configured to fit the seat imperfectly, to allow a seepage of the fluid after reaching the seat.

The disclosed embodiments describe a method, apparatus, and system for water management. At least one smart aquameter may be used to connect to a plumbed water system. The smart aquameter may measure a variety of sensor data, process, analyze, store, report, or control information related to the water system. The acoustic, pressure, and temperature characteristics of water in a plumbed system, amongst other things, may be used to identify which outlet is using water, for how long, and how much. This information, along with other relevant information, may be utilized to report, alert, optimize, inform, educate, and regulate the water system, for consumers, utility companies, and resource agencies.

A fluid supply monitoring system includes a fluid sensor configured to identify a flow rate of a fluid through a supply line. The system comprises a valve configured to control the flow rate through the supply line and a pressure sensor configured to detect a fluid pressure. A controller is configured to receive the flow rate data and identify fluid consumption from the supply line based on the flow rate. The controller is further configured to compare the fluid consumption of a usage event to one of a time limit and a volume limit. In response to the fluid consumption exceeding the time limit or the volume limit, the controller controls the valve to a closed position and identifies a potential fluid leak. With the valve in the closed position, the controller processes a verification procedure that identifies whether the potential fluid leak is an actual fluid leak.

Provided is an apparatus for regulating water flow to a structure. The apparatus generally comprises an electrically operated valve, sensors for temperature and flow-rate, and a module for communication. The remotely controllable shutoff valve contains a battery backup to provide power in case of an electrical outage. The apparatus is installed downstream from a structure's main water valve, shutting off the water supply according to a schedule that can be programmed into a controller, or smart-home hub.

Systems and methods are provided for optimally determining sensor or infrastructure placement in a fluid network, for determining an anomaly of interest in the fluid network, and for determining sensor coverage in a fluid network, which are based on a model of the fluid network represented by a directed graph.

A system to regulate fluid flow using a single unit is shown and described. The system uses a single valve interposed on at least one fluid supply line. The valve is normally closed, cutting off the flow of fluid in the at least one fluid supply line. The valve is in electrical communication with an occupancy sensor such that when the occupancy sensor is activated the valve is signaled to open, allowing flow of fluid in the fluid supply line.

The present invention provides a system to regulate fluid flow having a light switch that controls a light, wherein the light switch is in electrical communication with a wireless transmitter; and at least one valve interposed on at least one fluid supply line wherein said at least one valve is normally closed, cutting off the flow of fluid in the at least one fluid supply line, wherein the at least one valve is in electrical communication with a wireless receiver such that when the light switch is activated the wireless transmitter signals the wireless receiver to open the valve, allowing flow of fluid in the fluid supply line. The present invention also provides another system using a photocell switch to actuate the valve.
