摘要： The object of the invention is to create a central water-loss prevention system which blocks the main water feed pipe after intentional or unintentional removal or leakage of a water volume limit fixed for each application, said limit being, in the opinion of insurers, below the limit for causing damage for each application, and consequently prevents further removal. The central water-loss prevention system in a main water feed pipe is characterised in that a volume counter comparing a volume limit fixed for the corresponding application with the volume removed is operatively connected to a shut-off device of the main water feed pipe in such a manner that when the preset volume limit has flowed through a command closing the shut-off device is triggered and when a volume limit lower than the preset volume limit has flowed through there is no triggering of the command closing the shut-off device. The invention relates to a central water-loss prevention system in a main water feed pipe from which a plurality of removal points or consumers can be supplied with water, for example the main water feed pipe of a detached house or a house for several families, the main water feed pipe of an individual flat or an individual business or a construction site water supply pipe. In such cases normal water removal for any removal volumes must be ensured and, at the same time, unintentional discharge of water must be prevented at the removal points and in entire pipe systems.

摘要： When, according to the invention, the supply water installation in buildings, such as schools, institutions and the like, is protected with a leak protection system, which is capable of registering the presence of individuals in the building by means of movement sensors (5), these sensors (5) will be able to a apply a signal (5a) to a control box (4), so that forced opening of the shutoff valve (3) may take place in case of fire.
The control box (4) has two phases, viz. monitoring via the sensors (5) of a populated building and a depopulated building, respectively, and thereby the possibility of changing phase and thus switching the system from a leak monitoring system, which is capable of giving an alarm, but not of shutting off the water, to a leak protection system, which is capable of giving an alarm and shutting off the water. This switching takes place automatically, which gives the greatest possible certainty of both leak protection and pressure water in case of fire.

摘要： A method of managing and conserving water at a point of use, by installing a control panel and at least one electrically operated valve in a plumbing line, which valve can monitor at least pressure and flow rate, and allow the calculation of the total volume of flow in a particular line. The valve being controlled by a controller programmed to prevent water loss by monitoring the pressure and flow rate in a particular line to detect and prevent water consumption outside controlled parameters by shutting off the valve if the system detects an uncontrolled flow, such as faucet being left on, or a leaky toilet cistern, or the water flow in a zone exceeding a predetermined quota.

摘要： 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.
