    Abstract: A system for remotely measuring the characteristics of water passing through a plumbing control device (PCD) includes a sensor configured to measure characteristics of the water to obtain measured data. The sensor is also linked to a microcontroller of the PCD. An antenna board is linked, and configured to transmit power, to both the microcontroller and the sensor. The antenna board is configured to receive power transmitted from a mobile device and, in turn, transmit power to the microcontroller and the sensor. When power is not being transmitted from the antenna board, the microcontroller and the sensor may be powered off.

    Abstract: A sprinkler backflow alert system includes a sprinkler system, a building fire panel, a backflow preventor including at least one shut-off valve, a fluid detection system, and a tamper switch. The backflow preventor may be fluidly coupled upstream of the sprinkler system. The fluid detection system is configured to detect a discharge of water from the backflow preventor and generate a water discharge signal corresponding to the backflow discharge. The tamper switch is configured to detect a change in a position of the at least one shut-off valve and generate a tamper signal in the event the at least one shut-off valve is closed or partially closed. When a backflow discharge event occurs, a signal is sent to the fire panel triggering the building fire alarm as well as sending an alert to the local fire department and facility owner.

    Abstract: A system for remotely measuring the characteristics of water passing through a plumbing control device (PCD) includes a sensor within the interior of the PCD. The sensor is configured to measure characteristics of the water to obtain measured data. The sensor is also linked to a microcontroller of the PCD. An antenna board is linked, and configured to transmit power, to both the microcontroller and the sensor. A mobile device is configured to locate the antenna board. The mobile device transmits power to the antenna board which, in turn, transmits power to the microcontroller and the sensor. When power is not being transmitted from the antenna board, the microcontroller and the sensor are powered off.

    Abstract: The present disclosure is directed to systems and methods useful for backflow prevention system that includes an actuated valve, a valve controller, one or more upstream sensors, and one or more downstream sensors. Upon detecting conditions conducive to backflow through the system using either or both the one or more upstream sensors, and the one or more downstream sensors, the valve controller causes the actuated valve to close. The system may be enhanced through the use of a qualifying check valve disposed between the actuated valve and the one or more downstream sensors to slow or impede backflow through the system. The system may be enhanced by inclusion of a run-out length between the actuated valve and the one or more downstream sensors to account for the latency in the actuator causing the valve to transition to the CLOSED position.

    Abstract: Fluid detection systems and methods using the same are disclosed. In embodiments the fluid detection systems include a sensor module and an electronics module. The sensor module includes a sensor housing that includes a liquid flow path and a sensor element disposed around at least part of the liquid flow path. The sensor element can detect a capacitance of the liquid flow path and provide a sensor signal to a controller in the electronics module. The electronics module can determine a detected capacitance in the liquid flow path based at least in part on the sensor signal, and can determine whether a wet event has occurred based on a comparison of the detected capacitance to a threshold capacitance. Methods using the fluid detection systems and fluid supply systems including the fluid detection systems are also disclosed.

    Abstract: A test cock for determining an operating condition of a backflow prevention system includes a body portion having a distal end and a proximal end and a space defined within the body portion. A distal opening is provided on the body portion at the distal end and a proximal opening is provided on the body portion at the proximal end and the proximal opening is in fluid connection with the body portion space. A body portion fitting is disposed in the body portion and is providing a fluid connection with the body portion space. A fluid sensor is coupled to the body portion fitting and is in fluid connection with the body portion space. A rotating system fitting has a first end and a second end where the second end is provided in the body portion proximal opening.
