WARNING
Electrical shock can result in death or serious injury.
•Avoid contact with the leads and terminals.
Process leaks could result in death or serious injury.
•Install and tighten all four flange bolts before applying
pressure.
•Do not attempt to loosen or remove flange bolts while
the transmitter is in service.
Replacement equipment or spare parts not approved by
Rosemount Nuclear for use could reduce the pressure
retaining capabilities of the transmitter and may render
the instrument dangerous or adversely impact its
qualified status.
•Use only components supplied with the Rosemount
3152, 3153 or 3154 transmitter or designated by
Rosemount Nuclear as spare parts for the 3152, 3153
or 3154.
Improper assembly of mounting bracket to traditional
process flange can damage sensor module.
•For safe assembly of bracket to transmitter traditional
process flange, bolts must break back plane of flange
web (i.e. bolt hole), but must not contact module
housing. Use only the approved bolts supplied with
the bracket.
GENERAL
CONSIDERATIONS
Measurement accuracy depends upon proper installation of
the transmitter and its associated impulse piping and valves.
Mount the transmitter close to the process and use a minimum
of piping to achieve best accuracy. For flow measurement,
proper installation of the primary element is also critical to
accuracy. Also, consider the need for easy access, personnel
safety, practical field calibration and a suitable transmitter
environment. Transmitter installation should minimize the
effects of temperature gradients and fluctuations, and avoid
vibration and shock during normal operation.
MECHANICAL
CONSIDERATIONS
This section contains information you should consider when
preparing to mount the transmitter. Read this section carefully
before proceeding to the mechanical installation procedure.
Proper installation is mandatory to assure seismic
qualification.
WARNING
Do not attempt to loosen or remove flange bolts while the
transmitter is in service.

Installation
Mount the Rosemount 3150 Series transmitter to a rigid
support (i.e. one with a fundamental mechanical resonant
frequency of 40 Hz or greater). Two mounting options are
qualified for the transmitter: panel mount or 2-inch pipe mount.
A stainless steel panel bracket is provided with the 3154. For
the 3152 and 3153 transmitters, the user has the option of
specifying either the stamped carbon steel panel bracket or
the stainless steel panel bracket.
Refer to Figure 2-5 for qualified mounting configurations for
both the panel and pipe mount options.
Orientation with respect to gravity is not critical to qualification.
For maximum accuracy, zero the transmitter after installation
to cancel any zero shift that may occur due to liquid head
effect caused by mounting position.
NOTE
The transmitter is calibrated in an upright position at the
factory. Mounting the transmitter in another position may
cause the zero point to shift by an amount equivalent to the
internal liquid head within the sensor module induced by the
varied mounting position. For maximum accuracy, zero the
transmitter to cancel this effect per Section 3: Calibration.
Mount the process flanges with sufficient clearance for
process connections. For safety reasons, place the drain/vent
valves so the process fluid is directed away from possible
human contact when the vents are used. Also, consider that
access to the vent/drain valve(s) and process connection(s)
may be required for plant specific operations (i.e. calibration,
draining, etc.).
Process Connections and
Interfaces
Process tubing must be installed to prevent any added
mechanical stress on the transmitter under seismic conditions.
Use stress-relief loops in the process tubing or separately
support the process tubing close to the transmitter.
Typical connections on the transmitter flanges are 1/4-18 NPT
and 1/4 inch or 3/8 inch Swagelok®. Use your plant-approved,
qualified thread sealant when making threaded connections.
The end-user is responsible for the qualification of the
threaded seal interface on all 1/4-18 NPT interfaces.
Transmitters with flange options including 1/4 inch or 3/8 inch
Swagelok®are shipped with front ferrule, rear ferrule and nut.
Place these fittings on the tubing with the orientation and
relative position shown in Figure 2-1. Use process tubing with
1/4 inch or 3/8 inch outside diameter respectively, and of
suitable thickness for the pressure involved.

Figure 2-1 – Swagelok®Compression
Fitting Detail
Dimensions are nominal in inches (mm)
Assembly
The Swagelok®tube fittings come completely assembled and
are ready for immediate use. Do not disassemble them before
use because dirt or foreign materials may get into the fitting
and cause leaks. Insert the tubing into the Swagelok®tube
fitting, make sure the tubing rests firmly on the shoulder of the
fitting and the nut is finger tight. Tighten the nut one-and-one-
quarter turns. Do not over-tighten.
Re-assembly
To reconnect, insert the tubing with pre-swaged ferrules into
the fitting until the front ferrule sits in the fitting. Tighten the
nut by hand, then rotate one-quarter turn more or to the
originally secured position. Then tighten the nut slightly.
For more detailed information regarding the specifications and
use of Swagelok®tube fittings, refer to:
Fittings Catalog MS-01-140
“Gaugeable Tube Fittings and Adapter Fittings”
www.swagelok.com
Drain/Vent Valves
If drain/vent valves are opened to bleed process lines, torque
drain/vent valve stems to the value in Table 5-2 in Section 5:
Maintenance and Troubleshooting when closing.

Installation
Impulse Piping
The piping between the process and the transmitter must
accurately transfer the pressure to obtain accurate
measurements. There are five possible sources of error:
pressure transfer (such as obstruction), leaks, friction loss
(particularly if purging is used), trapped gas in a liquid line or
liquid in a gas line and density variations between the legs.
The best location for the transmitter in relation to the process
pipe depends on the process itself. Use the following
guidelines to determine transmitter location and placement of
impulse piping:
•Keep impulse piping as short as possible.
•For liquid service, slope the impulse piping at least 1
inch per foot (8 cm per meter) upward from the
transmitter toward the process tap (see Figure 2-2 for
details).
•For gas service, slope the impulse piping at least 1
inch per foot (8 cm per meter) downward from the
transmitter toward the process tap (see Figure 2-2 for
details).
•Avoid high points in liquid lines and low points in gas
lines.
•Make sure both impulse legs are the same
temperature.
•Use impulse piping of large enough diameter to avoid
friction effects and blockage.
•Vent all gas from liquid piping legs and internal to
transmitter process flange.
•Drain all liquid from gas piping legs and internal to
transmitter process flange.
•When using a sealing fluid, fill both piping legs to the
same level.
•When purging, make the purge connection close to
the process taps and purge through equal lengths of
the same size pipe – avoid purging through the
transmitter.
•Keep corrosive or hot process material out of direct
contact with the transmitter.
•Prevent sediment deposits in the impulse piping.
•Keep the liquid balanced on both legs of the impulse
piping.
•Avoid conditions that might allow process fluid to
freeze within the process flange.
•Make sure the impulse piping is of adequate strength
to be compatible with anticipated pressure.

Mounting Configuration
Refer to Figure 2-2 for examples of the following mounting
configurations:
Liquid Flow Measurement
•Place taps to the side of the line to prevent sediment
deposits on the process isolators.
•Mount the transmitter beside or below the taps so
gases vent into the process lines.
Gas Flow Measurement
•Place taps in the top or side of the line.
•Mount the transmitter beside or above the taps to
drain liquid into the process line.
Steam Flow Measurement
•Place taps to the side of the line.
•Mount the transmitter below the taps to ensure that
impulse piping will remain filled with condensate.
•Fill impulse lines with water to prevent steam from
contacting the transmitter directly and to ensure
accurate measurement start-up. Condensate
chambers are not typically necessary since the
volumetric displacement of the transmitter is
negligible.
NOTE
For steam service, do not blow down impulse piping through
the transmitter. Flush the lines with the transmitter isolated
and refill the lines with water before resuming measurement.
NOTE
The mounting configurations described above and depicted in
Figure 2-2 are based on general industry “best practice”
recommendations. Where applicable, specific plant approved
installation practices should be used.
NOTE
In steam or other elevated temperature services, it is
important that temperatures at the process flanges not exceed
250°F (121°C). In vacuum service, these limits are reduced to
220°F (104°C).

Examples (liquid, gas or steam)
Please note that transmitters depicted in Figure 2-2 are intended for reference only.
Conduit Connections
The conduit connections to the transmitter are threaded.
Options available are 1/2-14 NPT, M20 x 1.5, PG 13.5 and
G1/2. Housings with M20 x 1.5 threads are marked with “M20
x 1.5”. Two openings are available on the 3152 and 3153
transmitter housings for convenient installation. Close off the
unused opening with a compatible thread type stainless steel
plug. Use your plant-approved, qualified thread sealant on the
conduit connection threads.
IMPORTANT
For all 3152 and 3153 transmitters, install the conduit plug
(provided with the transmitter) in the unused conduit opening
per the torque values in Table 5-2 in Section 5: Maintenance
and Troubleshooting.
The 3154 has one conduit connection.
Use a qualified conduit seal at the conduit entry to prevent
moisture from entering the terminal side of the housing during
accident conditions. Certain option codes provide a factory-
installed, qualified electrical connector. To prevent excessive
mechanical stress during seismic disturbances, support the
conduit/connector cable near the transmitter. Install the
conduit seal in accordance with the manufacturer’s
instructions or use the procedure in this section.
NOTE
A Swagelok®rotatable two-piece 90 degree elbow is available
in two configurations: fully assembled to a 3150 Series
pressure transmitter or in a ready to assemble kit (Spare
Parts number 03152-0702-0001; see Manual Supplement
00809-0400-4835 for installation instructions). Please contact

Electronics Housing
The standard transmitter orientation is shown in dimensional
drawings found in this manual (see Figure 2-6). While rotation
of the electronics housing in the field is possible with special
instructions, it is not recommended. Please contact
Rosemount Nuclear prior to any attempt to rotate the electrical
housing.
ELECTRICAL
CONSIDERATIONS
This section contains information you should consider when
preparing to make electrical connections to the transmitter.
Read this section carefully before proceeding to the electrical
installation procedure.
Rosemount 3150 Series transmitters provide a 4-20 mA signal
when connected to a suitable dc power source. Figure 2-3
illustrates a typical signal loop consisting of a transmitter,
power supply, and various receivers (controller, indicator,
computer).
Figure 2-3 – Typical Transmitter
Wiring Connection
The power supply versus load limit relationship is shown in
Figure 2-4. See qualification reports for additional details.
The loop load is the sum of the resistance of the signal leads
and the load resistance of the receivers. Any power supply
ripple appears in the output signal.
