摘要： An indicator for the rate of volumetric fluid flow includes a housing having a fluid passageway therein and a rotor contained in the housing in a position so as to be rotated by fluid flowing through said passageway. The indicator also includes a Hall effect transducer positioned outside the housing, responsive to the rotation of the rotor. The transducer produces an output signal corresponding to the rate of rotation of the rotor, and thus to the rate of fluid flow through the housing passageway. Preferably, the rotor is a paddle wheel disposed on an axle in the housing. The axle and thus the paddle wheel are retained in the housing by entrapment against a removable housing cover. The housing is otherwise mechanically imperforate to any connection between the rotor and the transducer. The indicator can preferably include a plurality of rotors having different hydraulic characteristics, that is, which rotate at different speeds for a given rate of fluid flow, such that replacement of one rotor for another changes the range of fluid flow rates over which the indicator is responsive.

摘要： In a flow meter, a cylindrical member containing therein a vane wheel is fitted in a measuring chamber of a casing so as to be closely in contact with the peripheral wall of the casing, and a cover is put on the cylindrical member. Rectangular inlet and outlet nozzles in a side wall portion of the cylindrical member communicate with inlet and outlet ports of the casing, respectively. A pivot supporting the vane wheel is replaceably attached to a bottom portion of the cylindrical member. A supporting shaft of the vane wheel extends upward through a center opening in the cover to be connected to a measuring mechanism.

摘要： A valve unit for a flowing medium is combined with an electrical measuring system to provide measurement of the rate of flow of the medium. The valve unit is connected to a propeller-type rotor disposed in a conduit which communicates with the valve. The rotor incorporates a permanent magnet in at least one vane thereof and the measuring system includes a magnetic pulse generator which senses the magnetic field produced by the magnet and generates a corresponding train of pulses during the rotation of the rotor. An amplifier-differentiator connected to the pulse generator produces an output in accordance with the derivative of the pulses so as to provide an indication of the rate of flow.

摘要： A rotary fluid flowmeter device comprising a casing enclosing a chamber bounded partly by a fluid-tight but magnetically permeable partition, said chamber having an inlet and an outlet for the fluid of which the flow is to be metered, and a rotor having radially-directed, axially-extending blades being borne for rotation within the chamber, wherein in operation fluid entering the chamber through the inlet is directed towards and impinges upon the rotor blades to cause rotation of the rotor, and wherein the casing houses an electronic sensing circuit on the far side of the partition from said chamber, the circuit being adapted to produce an electronic pulse train the rate of which represents the rate of rotation of the rotor.

摘要： A sensor unit that is configured to improve the non-contact, magnetic interface on a gas meter. The configurations may include a pair of magnets that co-rotate in response to a magnet internal to the gas meter. At least one of the magnets may also move longitudinally in proximity to the internal magnet. This feature aligns the magnets with one another to ensure proper magnetic coupling with the internal magnet.
