Abstract: 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.

Abstract: The subject disclosure relates to power failure simulations, for example to test lighting systems, such as emergency lighting units or lighted signage. In some aspects, a pressure monitoring process of the disclosed technology can include steps for receiving a plurality of differential pressure measurements from the pressure sensor, determining whether to transmit pressure information to a management system based on at least two differential pressure measurements received from the pressure sensor, and transmitting the pressure information to the management system if a difference between the at least two differential pressure measurements exceeds a predetermined threshold. Systems and computer-readable media are also provided.

Abstract: A system that monitors toilets for leaks using in-toilet monitors with pressure sensors that are placed underwater in toilet tanks. Monitors can be dropped into tanks without additional wiring or installation; they may be battery powered and may transmit data wirelessly. Data may be analyzed by a server that detects leaks or other malfunctions. Pressure data may be filtered to remove the effect of barometric pressure, to measure the height of water in the tank. The system may learn the flush pressure change pattern for each toilet; pressure changes that do not match this pattern may indicate problems such as leaks. Data may indicate the type of leak, such as an open flapper or a leaking valve. Toilet monitors may measure temperature, and the system may generate alerts when freezing appears imminent. The system may keep flush counts for each toilet to support maintenance and water consumption measurement.
