    摘要: An adjustable tangent assembly for a positive displacement diaphragm gas meter is provided with a pair of concentric face gears coaxial with the axis of rotation of the crank shaft and accessible through a small plug hole in the meter cover. An adjusting tool inserted through the plug hole allows independent self locking adjustment of the timing and stroke with high resolution.

    摘要: An internal gate rotary vane fluid meter which has markedly improved performance as a result of precise control over the geometry and dimensions of the rotating elements and the fluid flow path. In particular, the outer diameter of the gate is maximized and the inlet and outlet passages of the meter are shaped to perpendicularly intersect the rotor vanes when the vanes are sealing against the respective ends of the meter crescent. Furthermore, the inlet and outlet passages each have a total cross-sectional area substantially equal to a vane area to provide substantially constant fluid velocity.

    摘要: An internal gate rotary vane fluid meter is provided with a direct gearless drive between the rotor and the gate mounted on parallel displaced shafts inside a housing. A plurality of timing discs mounted on the rotor are utilized for drivingly coupling and synchronizing the gate to the rotor.
