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.

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)
(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.

Procedure
1. Ensure that the side of the orifice plate marked inlet is facing upstream.
Quick Start Guide 9
Quick Start Guide April 2021
This stamping is found on the part of the orifice plate that extends beyond the orifice bodies.
2. Before pressurizing the line, ensure that the torque values are met. See and for torque requirements of manifold studs and orifice body
studs. See the appropriate transmitter manual for torque requirements of transmitter bolts.
3. Install the unit.
Option Description
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 see .
Units with threaded
Install the unit using the appropriate threaded
connection hardware. process connections.
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.
4. 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 for support locations.
