Abstract
An orifice installation for centering the orifice aperture within a plate carrying device is disclosed. The orifice installation uses an orifice plate in cooperation with a seal that surrounds the outer edge of the orifice plate to seal the plate to a fitting. Reliefs are formed in the nonsealing portion of the surface of the seal through which the orifice plate outer circumference protrudes. The carrying device is provided to receive the plate and the seal. A mechanism including an intermediate interface is provided to have contact between the carrying device and the protrusions in order to use the manufacturing tolerances of the plate and the carrying device to center the plate in the carrying device.
