Quick Start Guide
NOTICE
This guide provides basic guidelines for the installation of the Rosemount 9295 Primary Element. For
comprehensive instructions on configuration, diagnostics, maintenance, service or troubleshooting, refer to
the Rosemount 9295 Primary Element Reference Manual and appropriate transmitter reference manuals. The
manual and this guide are also available electronically on Emerson.com/Rosemount.
If the Rosemount 9295 Primary Element was ordered assembled to a Rosemount Pressure Transmitter,
Manifold or RTD, 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
Rosemount 214C (RTD) Quick Start Guide
Hazardous Area Approvals: This assembly is assembled from 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.
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 the transmitter, RTD or impulse lines/valves.
Doing so may result in meter damage and serious injury.

1.0 Before you begin
Before you begin the installation, consider the vibration and temperature limits
of the meter:
The vibration limit of the Rosemount 9295 primary element with direct
mount transmitter is 0.5g amplitude, 10-500Hz frequency range. If the
application exceeds the vibration limits above, mount the transmitter and
manifold remotely.
The process temperature limits are:
- Direct mount transmitter: -20 °F (-28 °C) to 450 °F (232 °C)
- Remote mount transmitter: -20 °F (-28 °C) to 850 °F (454 °C)

Quick Start Guide
2.0 Locate the installation point
Locate the primary element installation point. If possible, install the meter at
ground level to allow meter access. No straight run is required for disturbances
in Table 1. In all cases, if additional straight run is available, a best practice is to
position the Rosemount 9295 primary element where 80 percent of the run is
upstream of the meter and 20 percent is downstream.
For redundant transmitter installations, it is recommended that the primary
element be installed with a minimum of five diameters of straight run upstream
of the meter. In cases where this isn’t possible, please consult your EmersonTM
representative for recommendations.
Table 1. Straight Pipe Requirements (Distance in Number of Pipe Diameters)(1)(2)
(1) Consult an EmersonTM representative if a disturbance is not listed.
(2) Straight pipe lengths are measured from the upstream and downstream flanges of the Rosemount 9295 primary
element. A zero diameter requirement implies that the primary element can be installed directly adjacent to a
disturbance.

2.1 Reversing the electronics (transmitter and RTD)
The Rosemount 9295 primary element with direct mount transmitter has
reversible electronics. If there is interference in the mounting location, the
transmitter and RTD (if applicable) can be reinstalled on the opposite side of the
meter by following the directions below. To reverse the electronics, use
Figure 1, Figure 3, Table 2 and follow these instructions.
This operation 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.
1. (Not shown) Remove the opposite side head plus and RD assembly plug (if
applicable).
2. Remove the manifold/transmitter assembly and switch it to the opposite
side.
Install the electronics with the new gaskets that are provided.
If the meter is equipped with an RTD, the wiring will need to be removed
from the transmitter.
3. Rotate the transmitter 180° on the manifold, ensuring high and low pressure
ports match those on the Rosemount 9295 meter body.
4. Reinstall the bolts using a cross or star pattern. Refer to Table 2 for bolt
torque guidelines.
5. Remove the RTD assembly and install it on the opposite side.
6. If the wiring was unhooked from the transmitter, reinstall it.
7. (Not shown) Reinstall the opposite side head plugs and the RTD assembly
plug.

3.0 Orient the primary element
The primary element can be installed in any position around the circumference
of the pipe, provided the vents are positioned within the recommended zone 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, single or dual transmitter
and the flowmeter’s orientation in relation to the pipe.
For steam applications, remote mount is recommended for vertical flow
applications. For liquid applications, flow down is not a recommended
installation.
