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: A delivery system for controlling the flow of fluid is disclosed. The comprises a control valve comprising an electric control motor and a valve, and a hydraulic piston type motor including a shaft which is rotated when fluid flows through the system. The rate at which fluid flows into the system is measured by the hydraulic motor and is reflected by the rate at which the hydraulic motor shaft rotates. The rate at which fluid flows through the system is controlled by the control valve. The control valve is movable between a first position in which a first fluid flow rate through the system is achieved and a second position is which a second flow rate higher than the first rate is achieved. The control motor is responsive to an external signal which indicates a rate rotation for the control motor corresponding with a rate of fluid flow.
