Abstract

Systems and methods for monitoring and controlling water consumption in a water-supply system are disclosed using one or more sensors for generating signals indicative of the operation thereof. In one embodiment, a method of preventing freezing of a water conduit in a water-supply system comprises sensing, with a temperature sensor, a temperature at a location; and, if the sensed temperature falls below a predetermined threshold, sending, to at least one fluid control device interfaced with the conduit, at least one control signal to impede a flow of water through the conduit and to drain water from the conduit.

sensing, with a temperature sensor, a temperature at a location; and

if the sensed temperature falls below a predetermined threshold, sending, to at least one fluid control device interfaced with the conduit, at least one control signal to impede a flow of water through the conduit and to drain water from the conduit.

2. The method of claim 1, wherein the at least one control signal is sent to the at least one fluid control device by a standalone module.

3. The method of claim 1, wherein the at least one control signal is sent to the at least one fluid control device by an interface module in communication with a controller.

4. The method of claim 3, further comprising:

sending to the controller, by the interface module, a signal related to the sensed temperature; and

sending to the interface module, by the controller, control signals.

5. The method of claim 1, wherein the water conduit comprises a pipe.

6. The method of claim 1, wherein the at least one fluid control device comprises a first fluid control device and a second fluid control device, and wherein the at least one control signal comprises a first control signal sent to the first fluid control device and a second control signal sent to the second fluid control device.

7. The method of claim 1, wherein the at least one fluid control device comprises a valve.

8. The method of claim 1, wherein the location is proximate to the at least one fluid control device.

9. The method of claim 1, wherein the at least one control signal comprises a control signal to shut off a main supply line of the water-supply system.

10. The method of claim 1, wherein the predetermined threshold is user-configurable.

11. A system to prevent freezing of a water conduit in a water-supply system, the system comprising:

a controller configured to send control signals to at least one device in the water-supply system;

at least one fluid control device; and

an interface module configured to communicate with the controller and the at least one fluid control device, the interface module configured to receive, from a temperature sensor, information indicative of a sensed temperature, and to send, to the at least one fluid control device, at least one control signal responsive to the sensed temperature.

12. The system of claim 11, wherein the at least one fluid control device comprises a valve, and whereby the at least one fluid control device impedes the flow of water through the water conduit and drains water from the conduit when the fluid control device is interfaced with the conduit and the at least one control signal is received by the fluid control device.

13. The system of claim 11, wherein the at least one fluid control device comprises a first valve which when closed impedes a flow of water through the conduit and a second valve which when open permits water to drain from the conduit.

14. The system of claim 11, wherein the temperature sensor is wireless.

15. The system of claim 11, wherein the controller comprises a motherboard configured to receive the interface module.

16. The system of claim 11, wherein the interface module is configured to send, to the controller, status information indicative of an operational status in the water-supply system.
