A more convenient alternative to simple orifice plates is an assembly comprising an orifice plate mounted in a carrier that already has the correct tapping points fitted. ABB has a wide range of these carrier assemblies for different applications.
Each assembly comprises an orifice plate mounted in (or integral with) a carrier that already has the correct tapping points fitted.
The integral orifice carrier assembly is a one-piece orifice plate and carrier ring with integral corner differential pressure tappings and is designed to fit between raised-face flanges.
The split ring orifice carrier assembly is a dual-ring orifice carrier with differential pressure tappings and is designed to fit between raised face flanges. The carrier rings incorporate corner or flange taps.
