A liquid cooling distribution system can be installed to an information technology (IT) rack to deliver and distribute fluid to IT equipment. The liquid cooling system can include a fluid manifold and a container that is arranged to capture a fluid that leaks from the fluid manifold. A first fluid sensor can be arranged to detect the fluid at a first position in the container. A controller can be configured to reduce a flow of the fluid into the fluid manifold and pump out fluid from the fluid manifold, in response to the fluid in the container being detected at the first position. Further remedial measure can be taken based on various detected leak scenarios.

A vehicle includes an internal cabin. One or more areas are within the internal cabin. The one or more areas include one or more water-drawing components. A water supply system is within the internal cabin. The water supply system is configured to provide water to the one or more water-drawing components. A water leak detection system includes one or more sensing devices configured to detect water flow from the water supply system to the one or more water-drawing components. One or more shut-off valves are disposed on or within the water supply system. A control unit is in communication with the one or more sensing devices, the one or more shut-off valves, and the one or more water-drawing components. The control unit is configured to operate the one or more shut-off valves to stop the supply of water to the one or more water-drawing components in response to the one or more sensing devices detecting the water flow when the one or more water-drawing components are not in use.

Devices, systems and methods for leak detection are provided herein. Also provided are devices, systems and methods for monitoring and/or measuring fluid usage. In some aspects, a system comprising a sensor, a processing system, and a platform are provided. In some aspects, the sensor may be coupled to a spinning device. The sensor can be configured to detect fluid data, which can comprise, for example, displacement data of liquid and/or movement data associated with the liquid in a container and/or flow data associated with a flow of fluid in a conduit. The processing system can be coupled with the sensor and configured to communicate the fluid data. The platform can comprise an application communicatively coupled to one or more databases storing evaluation data (e.g., known pattern data) and configured to receive the fluid data and determine if there is a leak.

A pressure maintenance system for a dry pipe sprinkler system programmed to store and report compressor activation data from which development of a leak in a dry pipes section of a dry pipe sprinkler system can be ascertained based upon an abnormal increase in activation of the compressor, and a method for detecting development of a leak in a dry pipes section of a dry pipe sprinkler system employing the pressure maintenance system.

A water leak detection assembly for a toilet includes a housing and a flow sensor. The housing is mountable externally or internally to a tank of a toilet. The flow sensor is positionable in-line with a fill line that is engaged to the tank and detects a flow of water from the fill line into the tank. A microprocessor is engaged to and positioned in the housing and is operationally engaged to the flow sensor. The flow sensor is positioned to signal the microprocessor of the flow of water. Programming code positioned on the microprocessor enables the microprocessor to distinguish between signals from the flow sensor corresponding to a normal flow of water required for flushing the toilet and a leak of water from the tank into a bowl of the toilet. The microprocessor is positioned to selectively actuate an alert module to notify a user of the leak.

A leak detection system for plumbing fixtures may include a dual channel system (700) having two channels of water flow to measure fluid flow that is both intentional and accidental. A disclosed embodiment may include a body (710) that is sometimes fastened to a top plate (715) sometimes fastened with socket head cap screws (717). The dual fluid channels may comprise a lower default or first flow path (790). Water flowing though the lower or default path may pass through a paddle wheel assembly (760) and paddle wheel (762) wherein flow rate may be measured by a myriad of systems including magnets or other sensors deposed on the distal ends of the paddle wheel spokes. A leak detection system may also include a single channel system (800) with a flap system. Disclosed systems may include other types of leak measuring devices.

A gas leakage meter (100) for use onsite in a process plant comprises a housing (110) with an inlet (101), an outlet (102) and an inlet nozzle (111) fluidly connected to a unit to be tested (3) through a downstream connector (1040) and to the inlet (101), the housing (110) being filled with a liquid to a level (10). An inclined pipe (120) is arranged such that, in use, test gas released from the inlet nozzle (111) raises through a liquid and the inclined pipe (120) to a gas-collecting chamber (122) at an upper end of the inclined pipe. (120). The gas-collecting chamber (122) has a gas release valve (150; 170) for releasing test gas before a test period. Embodiments where the inclined pipe (120) is mounted on a pivot and alternative gas release valves (150, 170) are also disclosed.

The invention provides secure systems, methods and computer program products for monitoring fluid distribution within a fluid distribution network, and for validating received fluid distribution data, identifying unauthorized losses, and raising alerts in response to detection of unauthorized losses. The invention relies on a plurality of sensors disposed within the fluid distribution network, data received from said sensors, and validation and reconciliation of data based on a distributed ledger system, for detecting instances of unauthorized fluid loss.

Methods and related systems for operating a climate control system for an indoor space are disclosed. In an embodiment, the method includes operating an indoor fan of the climate control system to rotate an impeller of the indoor fan in a reverse rotational direction opposite a nominal rotational direction of the impeller. Additionally, the method includes determining an airflow of the indoor fan when the impeller of the indoor fan is rotated in the reverse rotational direction. Further, the method includes determining a duct leakage rate associated with at least one duct of the climate control system based on the determined airflow, wherein the at least one duct is sealed-off at an end thereof.

By monitoring pressure transients in a liquid within a liquid distribution system using only a single sensor, events such as the opening and closing of valves at specific fixtures are readily detected. The sensor, which can readily be coupled to a faucet bib, transmits an output signal to a computing device. Each such event can be identified by the device based by comparing characteristic features of the pressure transient waveform with previously observed characteristic features for events in the system. These characteristic features, which can include the varying pressure, derivative, and real Cepstrum of the pressure transient waveform, can be used to select a specific fixture where a valve open or close event has occurred. Flow to each fixture and leaks in the system can also be determined from the pressure transient signal. A second sensor disposed at a point disparate from the first sensor provides further event information.
