The present invention discloses a device for flow control of fluid in pipelines to various utility fluid outlets like water taps and the like by blocking fluid flow from pipeline to said utility fluid outlet when the flow exceeds a predetermined flow rate. In other word, the present invention discloses an automatic fluid flow controlling device for restricting and/or stopping flow of the fluid medium miming through the guiding means or the tubing system when fluid flow exceed a certain flow rate as well as stopping flow of the running fluid flow when fluid level in the vessel wherein the running fluid is being delivered reaches a certain height.

A state analysis device is capable of determining a state of the interior of piping with high precision, and includes: an index calculation means for deriving an index indicating the state of the piping, based on a flow speed of fluid flowing out of the piping, and a fluid pressure of the interior of the piping at two or more locations of the piping; and a determination means for determining the state of the piping, based on the index.

A water management system effective for managing and metering water usage and detecting and reducing water leaks is described herein. The water management system can detect a leak when a volume of water flow or change in water pressure detected by a water meter of the system is uncharacteristic for a given day and time of day at the node. Upon detecting the leak, the system alerts the user, and in some situations, remotely shuts off a water supply to preemptively address a water leakage issue.

A system for the automatic management of the wastewater and freshwater for recreational vehicles is disclosed. The system includes a plurality of sensors configured for monitoring a first volume of blackwater within a blackwater holding tank, a second volume of greywater within a greywater holding tank, and whether an egress conduit is attached to a sewage system. The system further includes a processor configured for receiving a plurality of first signals from the plurality of sensors and sending a plurality of second signals to at least one of a plurality of values within the system. The processor is configured for determining if the first volume and second volume exceeds a first predetermined maximum threshold and a second predetermined maximum threshold respectively, then transmitting one of the plurality of second signals to prevent matter and wastewater from entering at least one of the blackwater holding tank and greywater holding tank.

A drinking water supply system includes a drinking water line system, a plurality of drinking water withdrawal points connected to the drinking water line system, at least one sensor which is designed to determine measuring values, and a central control device which is designed to receive and evaluate the measuring values determined by the at least one sensor. The system also includes a presence detector designed to determine information about the presence of a person, or an acoustic sensor designed to measure measuring values for the volume. The central control device is designed to control the drinking water supply system as a function of the information about the presence of a person or as a function of the measured values for the volume. A method for controlling such a drinking water supply system and a computer program that causes the method to be carried out are also provided.

Systems and methods for predicting, detecting, and/or mitigating a pipe freeze are provided. A system for analyzing water in a plumbing system includes a sensor that is configured to measure pressure within a pipe in the plumbing system as a function of time, and a processor that is configured to determine a state of water within the pipe by analyzing the pressure within the pipe as a function of time. The state of the water includes a prediction that the water within the pipe will freeze and/or a determination that the water within the pipe has frozen. The sensor is arranged at a first location within the plumbing system that is remote from a second location within the plumbing system that corresponds to the state of the water.

A non-invasive thermal dispersion flow meter with chronometric monitor for fluid leak detection includes a heater, an ambient temperature sensor and a flow rate sensor which are configured to sense the temperature of a fluid in a conduit, and then monitor the flow of that fluid through the conduit. Based upon the ambient temperature sensor readings, the flow rate sensor and heater may be adjusted to optimize the operation of the system to detect leaks. Based on the sensor readings, the flow may be adjusted to prevent damage and leaks by relieving the system of excess pressure. Geographic location, occupancy sensors and occupant identifiers are used to control the system to facilitate operation and minimize leak damage when occupants are away.

The present disclosure provides a water supply system. The system comprises a central water supply, a plurality of water taps, at least one operation device located at one water tap, a piping system connecting the central water supply and the plurality of water taps, the piping system comprising a separate flow path from the central water supply to each water tap, and a controller for individually controlling a flow of water from the central water supply to the plurality of water taps and individually controlling an outlet temperature of the flow of water at an outlet of the central water supply. The controller is located at the central water supply, and the controller is operable via the operation device at the water tap.

A method for locating a leak (19) in a water supply network with a water source (11) and one or more water consumption meters (21, 22) on the consumer side. The method includes calculating a length of the pipe (17) between the consumption meter (21) and the leak (19) location based on a temporal temperature curve and a quantity of water flowing through the at least one consumption meter (21).

The invention relates to a drinking water supply system including a drinking water line system, a plurality of drinking water withdrawal points connected to the drinking water line system, at least one sensor which is designed to determine measuring values, a central control device which is designed to receive and evaluate the measuring values determined by the at least one sensor, a plurality of decentralized control elements which are designed to influence at different locations in the drinking water supply system one or more properties of the water guided in the drinking water supply system, wherein the central control device is designed to control the control elements for influencing the one or more properties of the water guided in the drinking water supply system, and wherein a plurality of control elements are or can be combined to form a virtual group.
