A fluid supply system includes: a backflow preventer; and a bypass coupled in parallel with the backflow preventer, the bypass comprising at least one bypass flow meter coupled to at least one check valve, at least one of the at least one bypass flow meter or the at least one check valve being configured to generate associated alarm data in response to flow of a fluid through the bypass and transmit a flow alarm signal to a building fire panel when the associated alarm data indicates that the flow of the fluid varies from an expected flow of the fluid.

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.

A sensor cartridge assembly for coupling in a fluid network. The cartridge assembly includes a tubular body including a spoke extending radially inward and distally out of the tubular body, and a threaded hollow end formed on the spoke. The spoke forms a conduit extending from an intermediate point of the tubular body into the threaded hollow end. The cartridge assembly includes a sensor assembly including a sensor head and a sensor lead extending from the sensor head through the conduit. Further, the cartridge assembly includes a nut threaded to the threaded hollow end to form a chamber, the nut including a distal annular rim. The sensor head is retained in the chamber by the distal annular rim of the nut so that the conduit and, thereby the sensor lead, are sealed from fluid in the fluid network.

A temperature and pressure relief valve apparatus including a body having a first conduit connected to a water heater and a second conduit connected to a discharge pipe. A valve member, positioned between the first and second conduits, is normally biased closed to prevent flow between the conduits. The valve member is configured such that when a temperature or pressure within the water heater exceeds a predetermined level, the valve member opens to relieve pressure and, in turn, water is released through the second conduit. A sensor is disposed about the second conduit and coupled to a controller. The controller measures a capacitance value of the second conduit, detects a change in the capacitance value indicating a presence of water in the second conduit, and asserts an alarm condition upon detection of the change in the second conduit capacitance value.

A system monitors gas flow and pressure to a gas appliance in a fluid network comprising an analyzer. The analyzer has a housing defining an inlet, an outlet, and an interior in fluid communication with the inlet and the outlet. At least one sensor is coupled to the analyzer and configured to generate at least one signal related to gas being supplied to the gas appliance. A smart device communicates with the analyzer, wherein the smart device has a user interface and is configured to monitor, store and display data. The smart device can present any or all of a plurality of parameters such as the flow of gas, a capacity of the flow of gas, a temperature, a pressure of the gas and the like to a user based on signals from sensors.

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.

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.

The present disclosure provides a clamp mechanism to secure a temperature sensor to a plumbing fixture. The clamp includes a first semicircular portion and a first sensor housing lobe; a second semicircular portion and a second sensor housing lobe; wherein the first and second sensor housing lobes being hingedly coupled together and defining a first bore between the first and second semicircular portions to fit around pipe structures and around a test cock, and wherein the first and second sensor housing lobes defining a second bore between the first and second sensor housing lobes to house a temperature sensor configured to generate temperature sensor data indicative of an ambient temperature around the plumbing fixture.

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.
