GENERAL CONSIDERATIONS
MECHANICAL CONSIDERATIONS
ENVIRONMENTAL CONSIDERATIONS
Measurement accuracy depends on proper installation of the transmitter and
impulse piping. Mount the transmitter close to the process and use a
minimum of impulse piping to achieve the best accuracy. Also, consider 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 (found in the box) in unused conduit opening
with a minimum of five threads engaged to comply with explosion-proof
requirements.
For material compatibility considerations, see document number
00816-0100-3045 on www.emersonprocess.com/rosemount.
NOTE
For steam service or for applications with process temperatures greater than
the limits of the transmitter, do not blow down impulse piping through the
transmitter. Flush lines with the blocking valves closed and refill lines with
water before resuming measurement.
Best practice is to mount the transmitter in an environment that has minimal
ambient temperature change. The transmitter electronics temperature
operating limits are -40 to 185 °F (-40 to 85 °C). Refer to Appendix A:
Reference Data which lists the sensing element operating limits. Mount the
transmitter so that it is not susceptible to vibration and mechanical shock and
does not have external contact with corrosive materials.

INSTALLATION PROCEDURES
Mount the Transmitter Rosemount 2088
The Rosemount 2088 Transmitter weighs approximately 2.44 lb. (1,11 kg). In
many cases, its compact size and light weight makes it possible to mount the
2088 directly to the impulse line without using an additional mounting bracket.
When this is not desirable, mount directly to a wall, panel, or two-inch pipe
using the optional mounting bracket (see Figure 2-3).
The 2088 offers several process connections. Use your plant-approved
thread sealant to ensure a leak-proof connection.
Rosemount 2090P
The Rosemount 2090P is designed to be mounted directly to the process pipe
using a weld spud (see Figure 2-7). Mount the transmitter using an existing
weld spud or install a new one using the instructions on page 2-11.
Rosemount 2090F
Rosemount 2088 and 2090
The Rosemount 2090F is designed to be mounted directly to the process pipe
using a standard sanitary fitting (see Figure 2-8). The transmitter is available
with either a 1
NOTE
Most transmitters are calibrated in the horizontal position. Mounting the
transmitter in any other position will shift the zero point to the equivalent
amount of liquid head pressure caused by the varied mounting position. To
reset zero point, refer to “Sensor Trim” on page 4-8.
Terminal Side of Electronics Housing
Mount the transmitter so the terminal side is accessible. Clearance of 0.75-in.
(19 mm) is required for cover removal. Use a conduit plug on the unused side
of the conduit opening.
Circuit Side of Electronics Housing
Provide 0.75 in. (19 mm) of clearance for units without an LCD display.
Provide 3 in. (76 mm) of clearance for units installed with an LCD display.
Cover Installation
Always ensure a proper seal by installing the electronics housing covers so
that metal contacts metal. Use Rosemount supplied o-rings.

Rosemount 2088 and 2090
Impulse Piping The piping between the process and the transmitter must accurately transfer
the pressure to obtain accurate measurements. There are six possible
sources of impulse piping 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.
The best location for the transmitter in relation to the process pipe is
dependent on the process. 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 in./foot (8 cm/m)
upward from the transmitter toward the process connection.
• For gas service, slope the impulse piping at least 1 in./foot (8 cm/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 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 (above 250 °F [121 °C]) process material out of
direct contact with the sensor module and flanges.
• Prevent sediment deposits in the impulse piping.
• Maintain equal leg of head pressure on both legs of the impulse piping.
• Avoid conditions that might allow process fluid to freeze within the
process flange.
Mounting Requirements
Impulse piping configurations depend on specific measurement conditions.
Refer to Figure 2-4 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 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 to drain liquid into
the process line.

GAS
SERVICE
STEAM SERVICE
LIQUID SERVICE
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.
• In steam service above 250 °F (121 °C), fill impulse lines with water to
prevent steam from contacting the transmitter directly and to ensure
accurate measurement start-up.
NOTE
For steam or other elevated temperature services, it is important that
temperatures at the process connection do not exceed the transmitter’s
process temperature limit, which is 250 °F (121 °C).

Process Connections Rosemount 2090P
Installing the Rosemount 2090P transmitter involves attaching a weld spud to
the tapped process vessel, attaching the transmitter to the weld spud, and
making electrical connections. If you intend to use an existing weld spud,
proceed to the transmitter section of this installation procedure (page 2-12).
NOTE
The Rosemount 2090P isolating diaphragm can be mounted flush with the
inside diameter of any vessel larger than three inches in diameter.
Installation of the weld spud should be performed by a skilled welder using a TIG welder.
Improper installation may result in weld spud distortion.
Weld Spud
Rosemount 2088 and 2090
1. Using the appropriate size hole saw, cut a hole in the process vessel
to accept the weld spud. The diameter for a weld spud with heat
isolator groove is 2.37 in. (60 mm); when compatible with 1-in. PMC
process connection style spud, diameter is 1.32 in. (33,4 mm). The
hole should produce a tight, uniform fit when coupled with the weld
spud.
2. Bevel the edge of the vessel hole to accept filler material (see Figure
2-5).
3. Remove the weld spud from the transmitter and remove the PTFE
gasket from the weld spud.
Excessive heat will distort the weld spud. Weld in sections, as shown in Figure 2-5,
cooling each section with a wet cloth. Allow adequate cooling between passes.
To reduce the chances of distorting the weld spud (for 1.5-in. connection), use a heat
sink—Rosemount Part Number 02088-0196-0005.
4. Position the weld spud in the vessel hole, place heat sink and tack
spud in place using the welding sequence shown in Figure 2-5. Cool
each section with a wet cloth before proceeding to the next section.
5. Weld the spud in place using 0.030 to 0.045 in. (0,762 to 1,143 mm)
stainless steel rod as filler in the bevelled area. Using between 100
and 125 amps., adjust the amperage for 0.080 in. (2,032 mm)

1. After the weld spud has cooled, remove the heat sink and install the
PTFE gasket into the weld spud. Ensure that the gasket is properly
positioned within the weld spud; improper placement could cause a
process leak (see Figure 2-6).
2. Position the transmitter into the spud and begin to engage the
threads. Rotate the transmitter prior to seating the threads completely
to enable access to the housing compartments, the conduit entry, and
the LCD Display.
3. Hand tighten the transmitter using the knurled retaining ring, then

CONFIGURE SECURITY AND ALARM
Rosemount 2088 and 2090
Write Protect
There are three security methods in the Rosemount 2088/2090 transmitter:
1. Security Jumper: prevents all writes to transmitter configuration.
2. Local Keys (Local Zero and Span) Software Lock Out: prevents
changes to transmitter range points via local zero and span
adjustment keys. With local keys security enabled, changes to
configuration are possible via HART.
3. Physical removal of Local Keys (Local Zero and Span) Magnetic
Buttons: removes ability to use local keys to make transmitter range
point adjustments. With removing local keys, changes to
configuration are possible via HART.
You can prevent changes to the transmitter configuration data with the write
protect jumper. Security is controlled by the security (write protect) jumper
located on the electronics board or LCD display. Position the jumper on the
transmitter circuit board in the “ON” position to prevent accidental or
deliberate change of configuration data.
If the transmitter write protection is in the “ON” position, the transmitter will not
accept any “writes” to its memory. Configuration changes, such as digital trim
and reranging, cannot take place when the transmitter security is on.

Rosemount 2088 and 2090
NOTE
If either the alarm or security jumper is dislodged or removed from its position,
the transmitter reverts to default alarm or security settings of: Alarm: Output
high; Security: Off
Configuring Transmitter Security and Alarm Jumper Procedure
To reposition the jumpers, follow the procedure described below.
1. Do not remove the transmitter covers in explosive atmospheres when
the circuit is live. If the transmitter is live, set the loop to manual and
remove power.
2. Remove the housing cover opposite the field terminal side. Do not
remove the transmitter covers in explosive atmospheres when the
circuit is live.
3. Reposition the jumpers as desired.
• Figure 2-9 shows the jumper positions for the 4-20 mA HART
Transmitter and 1-5 Vdc Low Power Transmitter.
4. Reattach the transmitter cover. Always ensure a proper seal by
installing the electronics housing covers so that metal contacts metal
to meet explosion-proof requirements.

ELECTRICAL CONSIDERATIONS
The wiring terminations on the Rosemount 2088/2090 are located in the side
of the transmitter housing marked “FIELD TERMINALS.” Access to these
terminations is required during installation and may be necessary during
periodic calibration of the transmitter.
NOTE
Make sure all electrical installation is in accordance with national and local
code requirements.
Power Supply The dc power supply should provide power to the transmitter with less than
one percent ripple. The total loop resistance load is the sum of the resistance
of the signal wires and the resistance load of the controller, indicator, and
other pieces of equipment in the loop. Note that the resistance of intrinsic
safety barriers, if used, must be included. Figure 2-10 shows the transmitter
power supply load limitations.
Figure 2-10. Load Limitation
Maximum Loop Resistance = 43.5 * (Power Supply Voltage – 10.5)
The Field communicator requires a minimum loop resistance of 250

Low power transmitters operates on 6-14 Vdc. The dc power supply should
provide power with less than two percent ripple. The V
load should be 100
out
kor greater.

Wiring
Rosemount 2088 and 2090
Do not connect the power signal wiring to the test terminals. Voltage may burn out
the reverse-polarity protection diode in the test connection.
NOTE
Use shielded twisted pairs to yield best results. To ensure proper
communication, use 24 AWG or larger wire, and do not exceed 5000 feet
(1500 meters).
All power to the transmitter is supplied over the signal wiring. Signal wiring
need not be shielded, but use twisted pairs for best results. Do not run
unshielded signal wiring in conduit or open trays with power wiring, or near
heavy electrical equipment. For high EMI/RFI environments, shielded twisted
pair cable should be used. To power the transmitter, connect the positive
power lead to the terminal marked “PWR/COMM+” and the negative power
lead to the terminal marked “–” (see Figure 2-11). Tighten the terminal screws
to ensure that proper contact is made. Avoid contact with the leads and the
terminals. No additional power wiring is required for transmitters with “S”
output. For “N” output code transmitters, connect positive signal lead to “test
+” and negative signal lead to terminal marked “-.”
To connect test equipment for monitoring the output of the Rosemount
2088/2090 transmitter during maintenance procedures, connect one lead to
the terminal labeled “TEST+” and the other lead to the terminal labeled “–”
(see Figure 2-11). Avoid contact with the leads and the terminals.
Signal wiring may be grounded at any one point on the measurement loop, or
it may be left ungrounded. The negative side of the power supply is a
recommended grounding point. The transmitter case may be grounded or left
ungrounded.
Conduit connections at the transmitter should be sealed to prevent moisture
accumulating in the field terminal side of the transmitter housing. Also, install
wiring with a drip loop with the bottom of the drip loop lower than the conduit
connection of the transmitter housing.
