Abstract: A metering apparatus for measuring the flow of water or other fluid through a conduit. The meter comprises a measuring chamber, in which is disposed a nutating ball and disc. A unitary biaxial member, comprising a drive shaft and a spindle having a longitudinal axis offset from that of the drive shaft, couples the ball and disc to a rotating magnet. The unitary biaxial member both controls the offset of the ball and disc from horizontal, such that it nutates in response to water flow through the meter, and translates this nutation to rotation of the magnet, allowing for measurement of water volume flowing through the measuring chamber.

Abstract: Plastic housings that are subjected to internal pressure and comprise a housing upper part, a housing lower part and a closure which connects both parts to one another. At the connecting point, the housing upper and lower part have a plurality of comb-like retaining columns shaped in a complementary manner with respect to one another such that the housing parts can be plugged together. The retaining columns are oriented in a direction in which tensile force between the housing upper part and the housing lower part is oriented when the housing is subjected to internal pressure. Retaining grooves which are oriented transversely to the effective direction of the tensile force are formed in two opposite surfaces of the retaining columns in each case. Retaining bodies which at least partially touch the areas formed by the retaining grooves and thus establish the connection can be introduced into the retaining grooves.

Abstract: A metering system for measuring a flow of petroleum and LPG. In embodiments of the invention, a magnetic drive is used to couple a measuring chamber, such as a known oscillating piston system, to a register or indicator, avoiding leakage and excessive wear due to passing a shaft through the wall of the chamber.

Abstract: A water meter housing assembly (10) comprises a cylindrical, plastic housing body (11), a non-cast housing bottom (13) of hydroformable or stamped brass, a single-piece strainer and sealing member (40) that is disposed in the housing bottom (13) and portions of non-cast hydroformable or stamped brass tubing (15) with spud ends (16, 17) for connection in a water supply line. The brass consists essentially of lead-free material. The assembly (10) is designed to provide a lower cost alternative to foundry cast meter housings. The assembly (10) also provides advantages in a method of vertical assembly that saves manufacturing cost.

Abstract: A fluid meter (10) has a casing (11) providing a measuring chamber (27) and an inlet (18) and outlet (19) communicating with the measuring chamber (27). A partition (20) in the chamber (27) separating said inlet (18) from said outlet (19). A disc (28, 48) is positioned in the chamber (27) and includes projections (36) or niches (57) which are disposed in an arc relative to a center of the disc (28, 48) and the casing is provided with integrally formed depressions (37) or with projections (56) disposed opposite the projections (36) or niches (57) on the disc (28) to be engaged the disc (28) as the disc (28, 48) is nutated with the result of counteracting forces imposed on said disc (28, 48) by fluid flow.

Abstract: A fuel dispenser receiving fuel from a fuel source and dispenses the fuel to an output device while metering the quantity of fuel dispensed to the output device. The fuel dispenser includes a housing. A inlet port in the housing couples the housing to the fuel source. An outlet port in the housing couples the housing to the output device. A meter chamber in the housing has a chamber inlet, a chamber outlet, and a chamber opening. An inlet passage extends from the inlet port to the chamber inlet for conveying fuel received from the fuel source from the inlet port to the meter chamber. An outlet passage extends from the meter chamber outlet to the outlet port for conveying fuel from the meter chamber to the outlet port. A nutating disk meter disposed within the meter chamber of the housing is for measuring the quantity of fuel flowing through the fuel dispenser. A chamber cover covers the opening and seals the nutating disk meter in the meter chamber.

Abstract: An air flow compensator for use with flow meters which includes a main slide element, a secondary slide element and first and second spring elements. The main slide element includes a magnetic insert in one end thereof and is movable toward a proximity sensor that detects the proximity of the magnetic insert. The first spring element biases both the main slide element and the secondary slide element away from the proximity sensor and the second spring element biases only the secondary slide element away from the proximity sensor. The secondary slide element is both movable together with the first slide element and independently movable with respect to the main slide element.

Abstract: The present invention provides a flow measuring machine measuring a flowing amount of fluid or gas, and more particularly to a measure driving apparatus for converting a flowing amount into a mechanical momentum, by wave vibration and for transferring the mechanical momentum to a signal generating apparatus, and a measure signal generating apparatus for transferring a turning effect of a rotor in a non-contact system to a sender to output a turning signal. The machine of the present invention more precisely converts the flowing force of the fluid or gas into a vibration force of wave motion of the rotor, thereby getting a precise measure. Further, since the rotor performs a line contact rolling motion with a housing, a driving loss due to friction can be reduced.

Abstract: An adapter for a meter chamber provides proportional metering of a flow through a maincase that is sufficiently accurate at large flow rates to avoid the unmetered loss of significant quantities of water. An essentially unobstructed passageway is provided under the meter chamber to provide a free flow of water through a path that can be made large enough to avoid flow blockage by debris, even if the path through the meter becomes blocked. Thus, the adapter is particularly useful for installation in residential fire service mains. The adapter includes a chamber housing into which the meter chamber may be inserted, a bypass plate to hold the meter chamber in place, and a bypass to provide the passageway through which the free flow of water flows. The chamber housing includes inlet and outlet apertures, as does the bypass.
