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 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

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.

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 10 for torque requirements of manifold studs

and orifice body studs. See the appropriate transmitter manual for torque

requirements of transmitter bolts.

Figure 10. 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)

Traditional body Enhanced support body

A. Transmitter bolts - 4⫻

B. Manifold studs - 4⫻

C. Orifice body studs - 2⫻

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 11.

3. Units with threaded process connections:

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 11. 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 11

for support locations.

2. Open equalizer, high, and low side valves.

3. Fill manifold and transmitter with water via drain vents.

4. Close low side valve.

5. Pressurize line.

6. Gently tap electronics body, manifold head, and integral orifice body with a

small wrench to dislodge any entrapped air.

7. Check the transmitter zero according to the transmitter product manual.
