Rosemount™ 9195 Wedge Meter
Assembly

NOTICE
This document provides basic installation guidelines for the Rosemount 9195 Wedge Meter
Assembly. For comprehensive instructions for detailed configuration, diagnostics,
maintenance, service, installation, or troubleshooting refer to the Rosemount 9195 Reference
Manual. The manual and this guide are also available electronically on Emerson.com/
Rosemount.
If the Rosemount 9195 Primary Element was ordered assembled to a Rosemount Pressure
Transmitter or a Rosemount 1199 Diaphragm Seal System, 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 4088 Quick Start Guide
•Rosemount 1199 Diaphragm Seal Quick Start Guide
•Rosemount 3051SAL Quick Start Guide
Hazardous Area Approvals for assemble-to flow meter components specified on distinct lines:
An assembly may be composed of certified pieces of equipment. The overall assembly is
subject to inspection by the authority having jurisdiction over the installation.
If the meter was ordered with a wireless transmitter, the battery will be shipped separately
due to freight carrier regulations.
WARNING
Process leaks may cause harm or result in death.
To avoid process leaks, only use gaskets and O-rings designed for the corresponding flange
to seal process connections.
Transmitter electronics maintenance should not be conducted on energized equipment
in a hazardous atmosphere.
Failure to comply with the requirements for intrinsic safety in a hazardous atmosphere could
result in an explosion.
If the process fluid is hazardous, the procedure outlined here should be modified as
required.
Failure to do so could result in serious injury to personnel or death.
If the line is pressurized, always open valves slowly.
Failure to do so could result in serious injury to personnel or death.
During installation never lift the meter by remote seal capillaries, the transmitter, RTD,
or impulse lines/valves.
Doing so may result in either meter damage or serious injury.

WARNING
Physical access
Unauthorized personnel may potentially cause significant damage to and/or
misconfiguration of end users’ equipment. This could be intentional or unintentional and
needs to be protected against.
Physical security is an important part of any security program and fundamental to protecting
your system. Restrict physical access by unauthorized personnel to protect end users’ assets.
This is true for all systems used within the facility.

(1) Consult an Emerson representative if a disturbance is not listed.
(2) Upstream straight pipe run diameters are measured from the upstream
pressure taps of the Rosemount 9195 primary element. Downstream
straight pipe run diameters are measured from the downstream
pressure taps.
(3) Straight pipe requirements are based on ISO 5167-6 for wedge ratios 0.2
≤ h/D ≤ 0 .6.

2.1 Reversing the transmitter
The Rosemount 9195 primary element with factory installed tubing
defaults to a left-handed orientation. If a right-handed meter
orientation is required, this can be specified in the model code.
If there is interference in the mounting location, the transmitter
electronics can be reinstalled on the opposite side of the meter by
following the directions below.
Note
This is only applicable to the Direct mount ½" NPT connection style,
option code "T" in the model number.
WARNING
This operation should not be conducted on either energized
equipment or in a hazardous atmosphere.
Always depressurize the system before disassembling the
compression fitting.
Failure to comply with the requirements for intrinsic safety in a
hazardous atmosphere could result in an explosion.
Procedure
1. Mark the tube at the edge of the compression nut. Later,
use these marks to ensure the tubing is fully seated in the
compression fitting.
Disassemble the compression fitting nuts at the tubing-to-
manifold connections.
2. Remove the bolts connecting the manifold to the mounting
bracket.
3. Remove the manifold from the mounting bracket.
4. Remove the transmitter from the manifold.
5. Rotate the transmitter 180º on the manifold, ensuring the high
and low pressure ports match those on the Rosemount 9195
meter body.
Tighten the bolts as shown in Table 2-2.
6. Position the tubing into the compression fittings on the
manifold on the desired side of the mounting bracket,
ensuring the high and low pressure sides of the transmitter
match that of the wedge primary element.
7. Install the manifold onto the mounting bracket loosely.

8. Tighten the compression fitting nuts to 1.25 turns past hand-
tight.
a) Insert the tube with preswaged ferrules into the fitting
until the front ferrule seats against the fitting body.
Note
If needed, lightly reapply lubricant to the body threads
and the rear surface of the back ferrule.
b) While holding the fitting body steady, rotate the nut
with a wrench to the previously pulled-up position, as
indicated by the marks on the tube and flats.
At this point, you will feel a significant increase in
resistance.
c) Slightly tighten the nut.
9. Finish tightening the manifold onto the mounting bracket.
10. Verify the flange bolts are protruding through the sensor
module before applying pressure.

3 Orient the primary element
The primary element should be installed as recommended below.
Manifold or flushing ring vents should be positioned to allow for
bleeding or venting. Orienting the unit within the recommended
zone will also prevent inaccurate measurements. Determine the
orientation based on the application type, mounting type, flow
direction, and the flow meter’s orientation in relation to the pipe.
For steam applications with ½-inch NPT branches, remote mount is
recommended for vertical flow applications. For liquid applications,
flow down is not a recommended installation.

Note
Recommended orientation for branches are at the 3:00 or 9:00
positions.

Based on Gas, Liquid, or Steam Fluid Types
Note
Vertical flow will add additional uncertainty. Refer to the
Rosemount 9195 Reference Manual for more information.
Note
Steam and liquid flowing vertically down can be associated with
increased signal noise and are generally not recommended.
Note
Generally, steam flowing vertically is not recommended.

Note
Vertical flow will add additional uncertainty. Refer to the
Rosemount 9195 Reference Manual for more information.
Note
Not applicable for remote seal applications.
Note
For remote mount installations, use stainless steel tubing with
the largest convenient internal diameter per site practices. A best
practice is to minimize the length of the impulse lines. For examples
of remote installation, refer to Figure 3-6, Figure 3-7, Figure 3-8, or
Figure 3-9.

4 Install the primary element
The unit must be oriented with the flow arrow pointing in the
direction of the flow; otherwise, the primary element will produce
erroneous readings. Upstream tap(s) should be connected to the
high (H) side of the transmitter and downstream tap(s) connected
to the low (L) side.
Refer to Figure 4-1.
Figure 4-1: Flow Direction
Procedure
1. For units using a ½ in NPT connection, ensure that all
connections are tight and sealed properly.
2. For units using a remote seal connection:
a) The remote seal comes standard with a sealing gasket.
When connecting the upper and lower housing make
sure the gasket is aligned properly on the gasket
sealing surface.
b) For flanged assemblies: when connecting the process
and mating flange, the bolts should be torqued to the
applicable flange requirements.
