Quick Start Guide
Step 1: Primary element location
To obtain published accuracy for a 1495 Orifice Plate, sufficient straight run is
required to produce a fully developed flow profile. Please see Appendix B of the
Rosemount 1495 Orifice Plate Manual (00809-0100-4792) for a list of required
straight pipe recommendations based on ISO 5167, AGA Report No. 3, and ASME
MFC 3M Standards. Shorter straight runs are possible, but accuracy will be
affected per the Standards. Consult the Factory for further information.
