Abstract: A system and method for filtering a fluid includes a manifold and a filter releasably connected to the manifold that includes a memory storage device. A filter valve in fluid communication with the manifold has an open position that allows the fluid to flow through the filter and a shut position that prevents the fluid from flowing through the filter valve. A sensor in fluid communication with the manifold generates a fluid parameter signal reflective of a characteristic of the fluid flowing through the manifold. A controller receives the fluid parameter signal and positions the filter valve to the shut position when the fluid parameter signal meets a predetermined fluid condition.

Abstract: Aspects herein include filter systems including short-range wireless tracking features to detect insertion and/or removal of filter elements from filter systems. In an embodiment, a filtration system is included having a housing including a fluid inlet and a fluid outlet. The housing can define an internal volume. A first filter element can be removably disposed within the housing. A short-range wireless communication tag can be associated with the first filter element. A short-range wireless communication reader can be associated with the housing, the reader configured to wirelessly send data to and receive data from the tag when the reader and the tag are at a distance that is less than or equal to a maximum communication distance. Removal of the first filter element from the housing can cause the distance between the tag and the reader to exceed the maximum communication distance. Other embodiments are also included herein.

Abstract: A control system for a water filter assembly comprising a filter having an RFID tag and an RFID sensor to generate a RFID signal containing data related to the filter. A valve assembly moves between a shut off position, an operational position directing the flowpath of the water supply through the filter, and a bypass position. A controller communicate with a lawn irrigation system to determine if the irrigation system is operative. When operative, the controller has the valve assembly switch to the bypass position. The controller also receives the RFID signal to verify if the filter is proper. The controller also receives a leak signal from a leak sensor and has the valve assembly automatically switch to the shut off position if a leak occurs. The controller can name the leak sensor with a location and indicate battery life of the leak sensor.

Abstract: In one example, a core cover includes an inner wall that defines a fluid passageway configured to communicate with an interior of a filter core when the core cover is engaged with the filter core. As well, the core cover includes an outer wall spaced apart from the inner wall, and a complementary structure located on the outer wall and configured to engage a corresponding complementary structure of a filter core. Finally, the core cover includes one or more indicia that indicate a flow rate, or range of flow rates, associated with the core cover.

Abstract: In general, techniques are described for filter media monitoring within a filtration system. The filter media monitoring techniques described herein include, for example, direct contact with the filter media, e.g., a sensor may be located inside a boundary defined by a surface of the filter media, or indirect contact with the filter media, e.g., a sensor may be located outside the boundary defined by the surface of the filter media such that the sensor does not make direct physical contact with the filter media being monitored.

Abstract: The present invention provides a system and method for transmitting information between a device within a housing to a second device, preferably a test or monitoring unit, outside of the housing. There are numerous issues associated with transferring information from within a sealed housing to an external device. In some cases, the use of wires inside the housing may be impractical, due to internal conditions, such as fluid flow, pressure or temperature. In one embodiment, the antenna of the external RF reading device is electrically connected to the dome of the housing. In another embodiment, the device within the housing is electrically connected to a housing component. In another embodiment, the gasket is used to pass information from within the housing to an external device.
