A lower portion of the main body may be coupled with a lower portion of the cover. Magnets may be installed in upper portions of the main body and the cover, respectively, such that the main body and the cover may be coupled with each other by a magnetic force.

An arrangement for installation in a fluid line network contains a fluid meter having a housing with a fluid inlet and a fluid outlet, and a volume measuring part. At least one connector, which is intended for connection to the housing of the fluid meter, is either equipped with an additional function or configured for the adaptation of an additional function on the connector. The connector has a connector inflow and a connector outflow. The fluid meter and the connector form a modular unit that can be installed in the fluid line network.

A drinking water supply system with a drinking water line system includes multiple drinking water removal points connected to the drinking water line system, at least one sensor, which is designed to determine measurement values, and a central controller, which is designed to receive and evaluate measurement values determined by the at least one sensor. Multiple sensors are provided which are designed to determine measurement values for one property or for different properties of the water being conducted in the drinking water supply system at different locations in the drinking water supply system, and the central controller is designed to receive and evaluate the measurement values determined by the sensors. One or more of the sensors is designed to determine measurement values for the drinking water quality of the water being conducted in the drinking water supply system. A method for controlling such a supply system is also provided.

A drinking water supply system with a drinking water line system includes multiple drinking water removal points connected to the drinking water line system, at least one sensor, which is designed to determine measurement values, and a central controller, which is designed to receive and evaluate the measurement values determined by the at least one sensor. The central controller is designed to control the control elements depending on the received measurement values. The drinking water line system has a drinking water line section for supplying drinking water to multiple drinking water removal points. A volumetric flow rate sensor is provided in order to measure the volumetric flow rate of the water in the drinking water line section and/or a pressure sensor is provided in order to measure the water pressure in the drinking water line section. The controller is designed to carry out a measure.

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.

The present invention provides an improved filtering system and method for filtering effluent water for use in irrigation and other applications. The improved filtering system offers significant advancements to the flow rate, efficiency, and reliability of effluent water filtration. The present invention provides systems and methods for filtering of effluent water with a multi-staged filter system, which are self-cleaning, requiring less down time and nearly continuous filtration function.

The present invention relates to a magnetic strainer that is configured to have a cap disposed in a filter insertion hole formed on the center of a branch pipe having an inlet and an outlet coupled to a pipe and to have upper and lower magnets arranged with repulsive forces, while placing a repulsive space therebetween, in such a manner as to be accommodated in both ends of a magnet case in a longitudinal direction of the magnet case to allow conductors in impurities to be easily collected to the inside of a filtering screen disposed between the filter insertion hole and the cap to filter the impurities, so that if ascending and descending means disposed under the magnet case operates, the upper magnet is descended to the repulsive space to easily remove the conductors collected on the top end surface of the magnet case.

A separator device for removing particles from suspension in a fluid includes a housing having first and second apertures for ingress and egress of fluid into and out of the housing. A first separator chamber is disposed at one end of the housing. A second separator chamber is disposed at the other end of the housing. A central chamber is disposed between the first and second separator chambers. The first and second separator chambers are apertured for ingress and egress of fluid from the central chamber, and each contains obstruction means to slow the flow of fluid within the chamber.

A separator device for removing particles from suspension in a fluid includes first and second fluid-carrying portions and a non-fluid-carrying spacer for linking the first and second fluid-carrying portions. Each of the fluid-carrying portions includes a socket for receiving an open end of a pipe and a connector for connection of the filter. The socket of the first fluid-carrying portion has a pipe receiving depth greater than that of the socket of the second fluid-carrying portion. The sockets of the first and second fluid-carrying portions are positioned on a common axis and facing away from each other when the fluid-carrying portions are linked by the spacer.
