before performing an operation preceded by this symbol.
Warnings
Explosions can result in death or serious injury.
• Do not remove the transmitter covers in explosive environments when the
circuit is live.
• Both transmitter covers must be fully engaged to meet
explosionproof requirements.
• Verify that the operating atmosphere of the transmitter is consistent with the
appropriate hazardous locations certifications.
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 Inc. for use
as spare parts could reduce the pressure retaining capabilities of the transmitter

GENERAL
CONSIDERATIONS Measurement accuracy depends upon proper installation of the
transmitter and impulse piping. Mount the transmitter close to the
process and use a minimum of piping to achieve best accuracy. Keep in
mind the need for easy access, personnel safety, practical field
calibration, and a suitable transmitter environment. Install the
transmitter to minimize vibration, shock, and temperature fluctuation.
IMPORTANT
Install the enclosed pipe plug in unused conduit openings with a
minimum of five threads engaged to comply with explosionproof
requirements. The transmitter is shipped with the plug installed on the
transmitters ordered with CSA explosionproof approval.
MECHANICAL
CONSIDERATIONS Figures 2-1 through 2-5 on pages 2-3 through 2-6 show dimensional
drawings of Model 3051 transmitters. Figure 2-8 on page 2-10 shows
installation examples. Figures 2-9 through 2-12 on pages 2-14 through
2-17 show dimensional drawings of mounting brackets.
NOTE
For Model 3051CD0 and 3051CD1, mount the transmitter solidly to
prevent tilting. A tilt in the physical transmitter may cause a zero shift
in the transmitter output.
NOTE
For steam service, do not blow down impulse piping through the
transmitter. Flush the lines with the blocking valves closed and refill
the lines with water before resuming measurement.
NOTE
When the transmitter is mounted on its side, position the Coplanar
flange to ensure proper venting or draining. Mount the flange as shown
in Figure 2-8 on page 2-10, keeping drain/vent connections on the
bottom for gas service and on the top for liquid service.
NOTE
The Model 3051 transmitter incorporates two independent seals
between the process connection and the conduit connection.

Installation
Mounting The Model 3051C Pressure Transmitter weighs 5.8 lbs (2,6 kg) without
additional options. Optional mounting brackets available with the
Model 3051 allow mounting to a panel, wall, or 2-inch pipe. The B4
Bracket Option for use with the Coplanar flange and the Model 3051T
is 304 SST with 316 SST bolts. Figures 2-9 and 2-10 on pages 2-14 and
2-15 show bracket dimensions and mounting configurations for the
B4 Option.
Bracket options B1, B2, B3, B7, B8, and B9 are sturdy polyurethane
painted carbon steel brackets designed for use in pipe or panel
mounting the traditional flange (H2, H3, H4, or H7 option). The B1–B3
brackets have carbon steel bolts, while the B7–B9 brackets have
stainless steel bolts. Bracket options BA and BC are stainless steel with
stainless steel bolts. Dimensionally, these brackets are identical to the
B1–B3 brackets used with the Rosemount Model 1151 Pressure
Transmitter except for the length of the bolts used to mount the
transmitter to the bracket. When installing the transmitter to one of
the mounting brackets, torque the bolts to 125 inch-pounds.
NOTE
The transmitter is calibrated in an upright position at the factory. If
you mount the transmitter in any other position, the zero point will
shift by an amount equivalent to the liquid head caused by the varied
mounting position. Triming the sensor may be necessary to compensate
for mounting positioning effects. CROSS REF HERE
Mounting Requirements Refer to Figure 2-8 for examples of the following mounting
configurations:
Liquid Flow Measurement
• Place taps to the side of the line to prevent sediment deposits on
the transmitter’s process isolators.
• Mount the transmitter beside or below the taps so gases can vent
into the process line.
• Mount drain/vent valve upward to allow gases to vent.
Gas Flow Measurement
• Place taps in the top or side of the line.
• Mount the transmitter beside or above the taps so liquid will
drain into the process line.
Steam Flow Measurement
• Place taps to the side of the line.
• Mount the transmitter below the taps to ensure that the impulse
piping will stay filled with condensate.
• Fill impulse lines with water to prevent the steam from
contacting the transmitter directly and to ensure accurate
measurement at start-up.

Rosemount Model 3051 Transmitter with FOUNDATIONTM fieldbus Protocol
2-10
NOTE
In steam or other elevated temperature services, it is important that
temperatures at the coplanar process flanges not exceed 250 °F
(121 °C) for transmitters with silicone fill or 185 °F (85 °C) for inert fill.
In vacuum service, these temperature limits are reduced to 220 °F
(104 °C) for silicone fill and 160 °F (71 °C) for inert fill. Models 3051L,
and the traditional flange allow higher temperatures.
Figure 2-8. Installation Examples
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, leaks, friction loss
(particularly if purging is used), trapped gas in a liquid line, liquid in a
gas line, and density variations between the legs.

Installation
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 m) upward from the transmitter toward the
process connection.
• For gas service, slope the impulse piping at least 1 inch per foot
(8 cm per m) downward from the transmitter toward the
process connection.
• Avoid high points in liquid lines and low points in gas lines.
• Make sure both impulse legs are the same temperature.
• Use impulse piping large enough to avoid friction effects
and blockage.
• Vent all gas from liquid piping legs.
• When measuring a 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 (above 250 °F [121 °C]) process material
out of direct contact with the sensor module and flanges.
• Prevent sediment deposits in the impulse piping.
• Keep the liquid head balanced on both legs of the impulse piping.
• Avoid conditions that might allow process fluid to freeze within
the process flange.
Process Connections Model 3051 process connections on the transmitter flange are
1/4-18 NPT. Flange adapter unions with 1/2–14 NPT connections are
supplied as standard. The threads are Class 2; use your plant-approved
lubricant or sealant when making the process connections. The process
connections on the transmitter flange are on 21/8-inch (54 mm) centers
to allow direct mounting to a three-valve or five-valve manifold. Rotate
one or both of the flange adapters to attain connection centers of
2inches(51mm),2
1/8inches (54 mm), or 21/4inches (57 mm). See
page 2-11 for information on the Model 3051T process connection.
Install and tighten all four flange bolts before applying pressure, or
process leakage will result. When properly installed, the flange bolts
will protrude through the top of the module housing. Do not attempt to
loosen or remove the flange bolts while the transmitter is in service.
To install adapters to a Coplanar flange, perform the following
procedure:
See “Safety Messages” on page 2-1 for complete warning information.

Rosemount Model 3051 Transmitter with FOUNDATIONTM fieldbus Protocol
2-12
1. Remove the flange bolts.
2. Leaving the flange in place, move the adapters into position with
the O-ring installed.
3. Clamp the adapters and the Coplanar flange to the transmitter
module using the larger of the bolts supplied.
4. Tighten the bolts. Refer to “Mounting Bolts” on page 2-17 for
torque specifications.
When compressed, Teflon®O-rings tend to cold flow, which aids in their
sealing capabilities. Whenever you remove flanges or adapters, visually
inspect the Teflon O-rings. Replace them if there are any signs of
damage, such as nicks or cuts. If they are undamaged, you may reuse
them. If you replace the O-rings, retorque the flange bolts after
installation to compensate for cold flow. Refer to the process sensor
body reassembly procedure in Section 4 Operation and Maintenance.
Failure to install proper flange adapter O-rings can cause process leaks, which can
result in death or serious injury.
Each style of Rosemount flange adapters requires a unique O-ring, as shown below.
Flange adapters are distinguished by their unique grooves.
Use only the O-ring designed to seal with an adapter. Refer to the Spare Parts list in
Appendix A: Specifications and Reference Data for the correct part numbers of the
flange adapters and O-rings designed for Model 3051 transmitters.

Housing Rotation The electronics housing can be rotated up to 180 degrees (left or right)
to improve field access or to better view the optional LCD meter. To
rotate the housing, perform the following procedure:
1. Loosen the housing rotation set screw using a 9/64-in. hex wrench.
NOTE
Do not rotate the housing more than 180 degrees without first
performing a disassembly procedure (see “Disassembly Procedures” on
page 4-1). Over-rotation will sever the electrical connection between the
sensor module and the electronics module.
2. Turn the housing up to 180 degrees to the left or right of its
original (as shipped) position.
3. Retighten the housing rotation set screw.
Do not apply torque directly to the sensor module. Rotation between the sensor module
and the process connection can damage the electronics. To avoid damage, apply torque
only to the hex-shaped process connection.
