  • The second off-center orifice plate type is called the segmental orifice plate, where the hole is not circular but rather just a segment of a concentric circle.

  • As with the eccentric orifice plate design, the segmental hole should be offset downward in gas flow applications and either upward or downward in liquid flow applications depending on the type of undesired material(s) in the flow stream.

Application:

This type is used primarily for slurries or extremely dirty gases where the flow may contain impurities heavier than the fluid.
