NOTICE
This document provides basic installation guidelines for the Rosemount1195 Integral Orifice Assembly. For
comprehensive instructions for detailed configuration, diagnostics, maintenance, service, installation, or
troubleshooting refer to the Rosemount 1195 Reference Ma nual
electronically on EmersonProcess.com /Rosemount
If the Rosemount 1195 Integral Orifice was ordered assembled to a Rosemount Pressure Transmitter, refer to
the following Quick Start Guides for information on configuration and hazardous locations cer tifications:

Process leaks may cause harm or result in death
To avoid process leaks, only use gaskets designed to seal with the corresponding flange and O-rings to seal
process connections.

2.0 Location and orientation
Install the Rosemount 1195 Integral Orifice in the correct location within the
piping branch to prevent inaccurate measurement caused by flow disturbances.
2.1 Straight pipe length
Use the upstream (U) and downstream (D) lengths provided below in
conjunction with figures below to determine the appropriate upstream (U) and
downstream (D) pipe lengths. For example, for a 1-in. line size with a beta ratio
(β) of 0.4 using installation of Figure 3, the straight length of upstream piping
required is 25 ⫻ 1 = 25-in., and downstream 10 ⫻ 1 = 10-in.
Note
The Rosemount 1195 Integral Orifice comes with the associated pipe lengths
(18D upstream and 8D downstream) when ordered with process pipe-end connections.
