Standard bore sizes are in 1/8-in. (3.2 mm) increments from ½-in. (12.7 mm) to 4-in. (101.6 mm) and in from 4
If required, Emerson Process Management can determine the orifice bore. Basic flow data is required at the time of order, see “Calculation Data Sheet” on page 1.
Bore tolerances are within AGA and ASME specifications. Available options allow the user to have the Rosemount 1495 sized for specific operating conditions. The “Orifice Plate Drawings” on page 6 specifies the physical parameters of the orifice from a detailed sizing calculation.
