Abstract
A basic housing for a fluid flow monitoring assembly comprising a sensing leakproof elongate hollow body formed from a non-magnetic, metallic material and pivotally mounting internally of same a vane assembly that at one end includes a vane adapted to be inserted into a fluid flow of piping, with the vane assembly being spring biased to pivot oppositely of the direction of fluid flow, about its pivot mounting, for zero or reduced fluid flow conditions, and at its other end including a permanent magnet for electrically actuating a switch mechanism; such elongate sensing body defines an open end through which the vane projects and closed a end adjacent the magnet, which elongate body adjustably mounts crosswise thereof at its closed end within the permeability of the magnet for set point adjustment purposes a novel flow switch assembly comprising a plastic housing that is also leakproof and potably mounts in hermetically sealed relation a commercially available reed type off-on switch in electrical circuit arrangement with lead wires having ends that extend from one end of such flow switch assembly, for connection in optional electrical circuiting of a variety of types, which flow sw…
