Orice Flanges
Meriam raised face orice ange unions are designed
to provide a convenient, accurate method for installing
orice plates. They incorporate accurately positioned
pressure taps for connecting the ow measuring
instruments. This eliminates the requirement of
locating pressure taps in the eld. Improper location
of these taps will result in poor accuracy of the ow
measuring system. These built-in taps also reduce eld
installation labor necessary for welding, drilling and/
or tapping pressure taps on the ow line itself. Meriam
orice anges are provided complete with nuts, bolts,
gaskets and plugs for installation with no other parts
required.
