Abstract
A orifice fitting for measuring fluid flow in fluid pipelines has a seal mechanism to seal the orifice plate to the orifice fitting body. The orifice fitting has an orifice plate carrier which moves downward into a seat slot to position an orifice plate in the fluid flow. An annular seal mounts to the orifice plate assembly for engaging and sealing against the downstream side of the seat slot. A retaining ring mounts to an upstream side of the plate carrier. Threads on the retaining ring allow the ring to be adjusted to set the overall width of the plate carrier assembly to provide an interference fit in the seat slot. Set screws in the retaining ring bear against the orifice plate, which in turn bears against the seal member.
