NOTICE
This document provides basic installation guidelines for the Rosemount1195. 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 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 certifications:
Rosemount 3051S Quick Start Guide
Rosemount 3051SMV Quick Start Guide
Rosemount 3051 Quick Start Guide
Rosemount 2051 Quick Start Guide
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 4, 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.

Note
For saturated steam that is not high quality, it is recommended to mount in a vertical line to
avoid damming effect of the liquid.
4.0 Primary element installation
1. Ensure the side of the orifice plate marked “inlet” is facing upstream. This
stamping is found on the part of the orifice plate that extends beyond the
orifice bodies. Before pressurizing line, insure torque values shown below are
met. See Table 2 and Figure 11 for torque requirements of manifold studs and
orifice body studs. See the appropriate transmitter manual for torque
requirements of transmitter bolts.
Figure 11. Rosemount 1195 Assembly Fastener Naming Convention
Table 2. Stud and Nut Torque Specifications(1)(2)
1. Studs and nuts should be tightened to specification in two to three steps following a cross pattern.
2. Never reuse gaskets. Always replace gaskets after disassembly to ensure proper seal.
Manifold studs Torque
All Line sizes and gasket types 32 lb-ft.(44 N-m)
Orifice body studs Torque
All line sizes and gasket types 60 lb-ft. (82 N-m)

Quick Start Guide
2. Units with flanged process connections:
a. Install the flanges in the process pipe. The distance between flanges should
be equal to the overall length of the flowmeter, plus clearance for gaskets.
b. Install the unit between the flanges, using studs, nuts, and gaskets
appropriate for the flange size/rating and process conditions. Proper
support is needed at the flange connections as shown below.
See Figure 12.
3. Units with threaded process conditions:
a. Install the unit using the appropriate threaded connection hardware.
4. Units with Socketweld Bodies:
a. To ensure perpendicularity of the pipe to the orifice fitting, the socket
diameter is smaller than the standard pipe OD. The pipe OD must be
machined-to-fit prior to welding.
b. To prevent damage, remove the transmitter prior to welding.
Figure 12. Recommended Support Locations for Installation
A. Support
B. No step
5. Once the Rosemount 1195 is installed ensure that it is supported properly and
take precautions to ensure that it is not used as a step. Refer to Figure 12 for
support locations.
