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.
