The present disclosure relates to a water detection device that includes a water-activated battery configured to switch from a dormant condition to an active condition upon contact with water, such that the water-activated battery supplies an electrical voltage upon contact with the water, an electronic circuit configured to receive the electrical voltage from the water-activated battery, where the electronic circuit is configured to communicate with an external, electronic device via one or more wireless communication techniques when the electronic circuit is powered by the electrical voltage, and where communication between the electronic circuit and the external, electronic device is an uninterrupted communication when the electronic circuit is receiving the electrical voltage from the water-activated battery, and a housing configured to receive the water-activated battery and the electronic circuit, where the housing has passageways configured to facilitate movement of the water into the housing and toward the battery.

To detect a leak in a pipe carrying a fluid, an elastic membrane circumferentially surrounds the pipe. A sensing device detects an expansion state of the membrane and a signaling device indicates the presence of the leak based on the expansion state of the membrane.

A system and method utilizing a light transfer protocol for a sensor that monitors hose assembly degradation is disclosed. The system includes a sensor having one or more first alignment features, a contactless switch, and a light transmitter configured to transmit a light transfer protocol. The light transfer protocol is a sensor unique identification code recognizable by a gateway device that automatically pairs the sensor to the gateway device.

A system and a method may detect underground water or gas leakage. The method may include receiving a first scan of an area including an underground gas pipe at a first polarization, the first scan including first microwave reflections of the area at a wavelength range of 3.8 cm to 1.3 m; receiving additional data, filtering electromagnetic noise from the first scan using the additional data; creating a water roughness map based on typical roughness values of a set of types of water sources and the filtered first scan; identifying one or more water accumulations at one or more locations along the gas pipe using the water roughness map and the filtered first scan and calculating the water content at the one or more locations along the gas pipe based on the identified one or more water accumulations.

Apparatus, assembly and method for investigating the integrity of a seal and sealant contained in a sealing fitting used in hazardous locations. The apparatus/assembly can include signal transmitters and signal receivers provided on a conduit system on either side of a sealing fitting. The apparatus/assembly can include probes placed on either side of a sealant within a sealing fitting, the probes placed in probe ports provided through the wall of the sealing fitting.

The present disclosure relates to a sensor system for monitoring the sealing of the connection between a sensor holder and a sensor that is mounted on the sensor holder. The sensor system includes a sensor holder, a sensor that is mounted on the sensor holder, and a leakage detector with a channel, which is arranged in the sensor holder and consists of one or more straight sections that are mounted perpendicular or parallel to the longitudinal axis of the sensor.

A method of inspecting a leak detection system in a short time is disclosed. The leak detection system includes a leak detection line, an on-off valve, a flow mater, an operation controller configured to detect a fluid leak from a fluid line based on a first flow rate measured by the flow mater, a drain line, and a drain valve attached to the drain line. The inspection method includes: opening the on-off valve and the drain valve, with a supply valve and a return valve closed; measuring a second flow rate of fluid in the leak detection line by the flow mater; and determining that the leak detection system has a defect when the second flow rate is lower than a predetermined reference value.

The present disclosure relates to a tangible, non-transitory, machine-readable medium, having machine-readable instructions to pair a water detection device of a plurality of water detection devices with a user account via a user device, receive a first signal indicative of a location of the water detection device from the user device, receive a second signal indicative of a personalized message to be sent to the user device upon a detection event of the water detection device, and display a list of the plurality of water detection devices and corresponding locations of each water detection device of the plurality of water detection devices on the user device.
