Abstract: A backflow preventer including a body having an inlet for connection to an upstream portion of a plumbing system and an outlet for connection to a downstream portion of the plumbing system, a first check valve and a second check valve located in the body for preventing the reverse flow of water between the outlet and the inlet. An inlet pressure zone is positioned between the inlet and the first check valve, an outlet pressure zone is positioned between the outlet and the second check valve, and an intermediate pressure zone is positioned between the first and the second check valves. Position sensors sense the positions of the check valves, and pressure sensors sense the pressures in the zone. A controller in communication with the position sensors and the pressure sensors calculates the opening and closing pressures of the check valves.

Abstract: A backflow preventer for preventing a reverse flow of water in a plumbing system including a body having an inlet and an outlet. The body forms an intermediate zone between the inlet and outlet. An inlet check valve prevents the reverse flow of water from the intermediate zone through the inlet. An outlet check valve prevents the flow of water from the outlet into the intermediate zone. An inlet pressure sensor, an intermediate pressure sensor and an outlet pressure sensor provide readings for the respective zones. A controller monitors a pressure differential between the outlet pressure zone and the intermediate pressure zone to compare the pressure differential to a pre-set range. The controller generates a warning/error message when the pressure differential is outside the pre-set range. The controller can also monitor an inlet pressure in the inlet zone to generate a message if the inlet pressure varies inappropriately.

Abstract: A wireless communication system includes a plurality of sensors and a device. Each sensor is configured to measure data and communicate over a network using low power signal communication. The device is connected to an in-wall power source and configured to wirelessly communicate over the network using low power signal communication. Further, the device is configured to transmit data from the sensors to a remote gateway using high power signal communication.
