Multi Hole Universal Orifice
Plates
Multi Hole Universal orifice plates are intended for use
in non-fiscal measurement applications. They can be
used within orifice meters (see Roto-Boss™ brochure),
some types of Orifice Flange Unions, and also in Annular
Chambers. They are termed as “universal” as they are manufactured to industry standard outer diameters and
plate thicknesses to comply with measurement standards
such as MFC-3M, ISO 5167 and AGA 3.
