Orifice Plate TypeOP
Outline
Orifice Plates are most widely used flow element because of simple shape, easy installation and change, low cost, and high reliability.
There are various types such as: Concentric sharp edge Orifice, Eccentric Orifice, Segmental Orifice, Quadrant Orifice,
D・D/2 taps shall be used for those of sizes 200A(8 inches) and upper.
For those less than 200A, the following types are generally used.
Type OR: Orifice flange assembly combined with orifice ring.
Type OF: Orifice flange assembly combined with orifice flange.
Other than the above, we also have the following types.
