    摘要: A flowmeter includes a conduit having an elbow portion and a straight section downstream of the elbow. A turbine is mounted inside the conduit in the straight section adjacent the elbow portion. The turbine occupies less than the entire cross section of the conduit and is disposed adjacent the side of the conduit which receives the laminar flow exiting from the elbow portion. A permanent magnet is mounted on the turbine, the rotation of which is picked up by a Hall-effect sensor mounted in a cavity in a wall of the conduit.

    摘要: A control valve for a fluid treatment system, such as a water softener or a water filter, includes a manifold which mounts a pair of open-ended, cylindrical valve bodies having ports in fluid communication with passages in the manifold. Interchangeable single and double poppet valve assemblies are received into the open ends of the valve body. The poppet valve assemblies have diaphragm valve actuators disposed between chambers that are in fluid communication with selective ones of an array of pilot valves that are also mounted on the manifold. The valve assemblies may be piloted to one position by a spring. A tank adapter connects the manifold to a treatment tank. The tank adapter can be connected to the manifold in two alternate alignments which connect passages in the manifold to the top and bottom of the treatment tank so that co-current or countercurrent flow of regenerative fluid and the fluid to be treated can be alternately selected. A variety of sequences of flow paths can be selected by selection of the interchangeable poppet valve assemblies, by plugging selected ports in the valve housing, and by capping open, unused ends of the valve bodies.
