NOTICE
This document provides basic installation guidelines for the Rosemount 1195 Integral Orifice
Assembly. For comprehensive instructions for detailed configuration, diagnostics, maintenance,
service, installation, or troubleshooting refer to the Rosemount 1195 Reference Manual. The manual
and this guide are also available electronically on www.emerson.com.
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
certifications:

WARNING
Process leaks could result in death or serious injury.
To avoid process leaks, only use the gasket designed to seal with the corresponding flange adapter. To
avoid process leaks, only use the O-ring designed to seal with the corresponding flange adapter.

2 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 (×) of 0.4 using installation of , the straight length of upstream
piping required is 25 x 1 = 25-in., and downstream 10 x 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.
