  • Patent number: 9783433
    Abstract: Water treatment and valve control systems and apparatuses, and methods of using the same, are disclosed. In some examples, the apparatuses, systems, and methods include use of a rotary position sensor and one or more rotatable elements configured to, when moving from an initial rotational position to subsequent rotational positions, move one or more element of a valve assembly. In various examples of the apparatuses, systems, and methods, the rotatable element rotates directly from one rotational position to another rotational position. In certain examples, the rotary position sensor measures an electrical resistance value to detect the rotational position of the rotatable element.

  • Publication number: 20160052798
    Abstract: Liquid treatment systems (e.g., water treatment systems) with enhanced components and systems are disclosed. For example, the water treatment system may be enhanced by incorporating a location determination component and one or more measurement components (e.g., to measure temperature, flow, pH, composition, etc.). A data store of location information may be created comprising current and/or historical location of the water treatment system. Using transmission capabilities, the water treatment system may transmit collected data to a remote server for, inter alia, storage, aggregation, filtering, and/or analysis. Collectively, the aggregate data from a plurality of networked water treatment systems may form a repository of information that offers synergistic benefits that improve numerous aspects of water treatment systems and the related systems and users to which those water treatment systems provide service.

  • Patent number: 6491181
    Abstract: A treatment tank for a water conditioning apparatus includes a tank head with a wall with an interior surface and a noncircular rim that defines a first through hole in the wall. A generally cylindrical flange defines a first aperture and has a first nipple portion with a periphery and a noncircular portion radially extending from the periphery of the nipple portion. The noncircular portion is configured to matingly engage the noncircular rim so that contact between the noncircular rim and the noncircular portion prevents rotation of the flange relative to the tank head. A first fastener is engageable on the first nipple portion to secure the flange on the tank head through contact between the fastener and the tank head.
