Remote monitoring of water distribution system
A liquid monitoring system includes a remote measurement device located at a location of the fire hydrant that is in contact with water provided by a water main. The remote measurement device has sensors that measure characteristics of the water and a communication interface that transmits measured information to a communication network device that may be located elsewhere on the fire hydrant. The communication network device communicates with a communication network.

6. The system of claim 1 , wherein the at least one sensor comprises a pressure sensor.
7. The system of claim 6 , wherein the communication interface is configured to transmit a warning based on a comparison of a measured pressure by the pressure sensor and one or more thresholds.
8. The system of claim 1 , further comprising a communication network device, the communication network device comprising a second communication interface configured to receive the information representative of the one or more characteristics from the communication interface.
9. The system of claim 8 , wherein the communication network device is located within an upper portion of the dry-barrel fire hydrant.
10. The system of claim 8 , wherein the communication interface comprises one of a wireless communication interface or a wired interface and the second communication interface comprises a corresponding one of a wireless communication interface or a wired interface.
11. The system of claim 8 , further comprises:
a wire attached to each of the communication interface and the second communication interface; and
wherein the wire is routed between the communication interface and the second communication interface via one of an interior cavity of a valve stem of the dry-barrel fire hydrant or an interior cavity of a barrel of the dry-barrel fire hydrant.
12. A monitoring system for a fire hydrant connected to a water distribution system, the monitoring system comprising:
a valve configured to control a flow of water through the fire hydrant, the valve comprising:
a seat ring; and
a valve plate assembly, the valve plate assembly being movable into contact with the seat ring to form a seal between the valve plate assembly and the seat ring to prevent the flow of water through the fire hydrant, the valve plate assembly comprising an exterior surface located opposite the seat ring and in contact with water in the fire hydrant; and
a measuring system configured to measure at least one characteristic of water in contact with the valve, the measuring system comprising:
at least one sensor integral with the exterior surface of the valve plate assembly and configured to measure the at least one characteristic of the water; and
a device communicatively coupled to the at least one sensor to receive information from the at least one sensor indicative of the measured at least one characteristic.
13. The monitoring system of claim 12 , wherein the at least one sensor is located within one or more of a channel of the valve plate assembly or a reservoir of the valve plate assembly.
14. The monitoring system of claim 12 , wherein the at least one sensor comprises a pressure sensor.
15. The monitoring system of claim 12 , wherein the at least one sensor is configured to provide information relating to a temperature of the water.
16. The monitoring system of claim 12 , wherein the device is located at a position in the fire hydrant that is opposite the exterior surface of the valve plate assembly.
17. The monitoring system of claim 16 , wherein the device is located within an upper portion of the fire hydrant.
18. The monitoring system of claim 12 , wherein the measuring system further comprises at least one wire connecting the at least one sensor and the device.
19. The monitoring system of claim 18 , wherein the wire is routed between the at least one sensor and the device through the valve plate assembly and via one of an interior cavity of a valve stem of the fire hydrant or an interior cavity of a barrel of the fire hydrant.
20. The monitoring system of claim 12 , wherein the device is configured to communicate with a central monitoring system for the water distribution system via a wireless communication network.
21. A method for measuring a one or more characteristics of a liquid at a valve of a fire hydrant, comprising:
integrating a remote measurement device with a valve plate, wherein the valve plate has a sealing surface and an exposed surface opposite the sealing surface;
sensing, with at least one sensor of the remote measurement device, one or more characteristics of the liquid;
receiving, by the remote measurement device, a signal indicative of the one or more sensed characteristics of the liquid from the at least one sensor;
transmitting, from a communication interface of the remote measurement device, information representative of the one or more sensed characteristics.
22. The method of claim 21 , further comprising locating the at least one sensor within one or more of a channel of the valve plate or a reservoir of the valve plate.
23. The method of claim 21 , wherein the transmitting information further includes wirelessly transmitting information to a communication network device located in the fire hydrant.
24. The method of claim 21 , wherein the transmitting information further includes transmitting information to a communication network device located in the fire hydrant via a wire, wherein the wire is routed between the remote measurement device and the communication network device via one of an interior cavity of a valve stem of the fire hydrant or an interior cavity of a barrel of the fire hydrant.
