This document provides basic installation guidelines for the Rosemount 8732. It does not
provide instructions for detailed configuration, diagnostics, maintenance, service,
troubleshooting, explosion-proof, flameproof, or intrinsically safe (I.S.) installations. Refer
to the Rosemount 8732 reference manual (document number 00809-0100-4665) for
more instructions. The manual and this QIG are also available electronically on
www.rosemount.com.
Failure to follow these installation guidelines could result in death or serious
injury:
Installation and servicing instructions are for use by qualified personnel only. Do not
perform any servicing other than that contained in the operating instructions, unless
qualified. Verify that the operating environment of the sensor and transmitter is consistent
with the appropriate FM, CSA, ATEX, or IECEx approval.
Do not connect a Rosemount 8732 to a non-Rosemount sensor that is located in an
explosive atmosphere.
December 2012
The sensor liner is vulnerable to handling damage. Never place anything through the
sensor for the purpose of lifting or gaining leverage. Liner damage can render the sensor
useless.
To avoid possible damage to the sensor liner ends, do not use metallic or spiral-wound
gaskets. If frequent removal is anticipated, take precautions to protect the liner ends.
Short spool pieces attached to the sensor ends are often used for protection.
Correct flange bolt tightening is crucial for proper sensor operation and life. All bolts must
be tightened in the proper sequence to the specified torque limits. Failure to observe
these instructions could result in severe damage to the sensor lining and possible sensor
replacement.
Rosemount 8705 Magnetic Flowtube units ordered with non-standard paint options may
be subject to electrostatic discharge.
To avoid electrostatic charge build-up, do not rub the meter body with a dry cloth or clean
with solvents.

Rosemount 8732
Before installing the Rosemount 8732 Magnetic Flowmeter Transmitter, there are several
pre-installation steps that should be completed to make the installation process easier:
• Identify the options and configurations that apply to your application
• Set the hardware switches if necessary
• Consider mechanical, electrical, and environmental requirements
Mechanical Considerations
The mounting site for the Rosemount 8732 transmitter should provide enough room for
secure mounting, easy access to conduit ports, full opening of the transmitter covers, and
easy readability of the display screen (see Figure 1).
If the Rosemount 8732 is mounted separately from the sensor, it is not subject to limitations
that might apply to the sensor.

Environmental Considerations
To ensure maximum transmitter life, avoid excessive heat and vibration. Typical problem
areas include:
• High-vibration lines with integrally mounted transmitters
• Warm-climate installations in direct sunlight
• Outdoor installations in cold climates.
Remote-mounted transmitters may be installed in the control room to protect the electronics
from the harsh environment and provide easy access for configuration or service.
Both remotely and integrally mounted Rosemount 8732 transmitters require external power
so there must be access to a suitable power source.
Installation Procedures
Rosemount 8732 installation includes both detailed mechanical and electrical installation
procedures.
Mount the Transmitter
At a remote site the transmitter may be mounted on a pipe up to two inches in diameter or
against a flat surface.
Pipe Mounting
To mount the transmitter on a pipe:
1. Attach the mounting bracket to the pipe using the mounting hardware.
2. Attach the Rosemount 8732 to the mounting bracket using the mounting screws.
Hardware Jumpers/Switches
The 8732 PROFIBUS PA electronics board is equipped with two user-selectable hardware
switches. These switches do not have any functionality and should be left in the default
positions as listed below:
Simulate Enable: OFF
Transmitter Security: OFF
Changing the switch position will have no effect on the functionality of the electronics.
Electrical Considerations
Before making any electrical connections to the Rosemount 8732, consider local and plant
electrical standards and be sure to have the proper power supply, conduit, and other
accessories necessary to comply with these standards.
Rotate Transmitter Housing
The electronics housing can be rotated on the sensor in 90° increments by loosening the
four mounting bolts on the bottom of the housing, and reinstalling the bolts. When the
housing is returned to its original position, be sure the surface is clean and there is no gap
between the housing and the sensor. When rotating the housing more than 90° , be sure to
disconnect the wiring from the electronics board and reconnect once the housing is securely
tightened in the desired orientation.

Handle all parts carefully to prevent damage. Whenever possible, transport the system to
the installation site in the original shipping containers. PTFE-lined sensors are shipped with
end covers that protect it from both mechanical damage and normal unrestrained distortion.
Remove the end covers just before installation.
Figure 2. Rosemount 8705 Sensor Support for Handling
Rosemount 8732
Upstream/Downstream Piping
T o ensure specification accuracy over widely varying process conditions, install the sensor a
minimum of five straight pipe diameters upstream and two pipe diameters downstream from
the electrode plane (see Figure 3).
Figure 3. Upstream and Downstream StraightPipe Diameters
Installations with reduced straight runs from 0 to 5 pipe diameters are possible. In reduced
straight pipe run installations, performance will shift. Reported flow rates will still be highly
repeatable.

Flow Direction
The sensor should be mounted so the FORWARD end of the flow arrow, shown on the
sensor identification tag, points in the direction of flow through the sensor.
Sensor Location
The sensor should be installed in a position that ensures the sensor remains full during
operation. Vertical installation allows upward process fluid flow and keeps the
cross-sectional area full, regardless of flow rate. Horizontal installation should be restricted
to low piping sections that are normally full.
Figure 4. Sensor Orientation
The electrodes in the sensor are properly orientated when the two measurement electrodes
are in the 3 and 9 o’clock positions or within 45° from the vertical, as shown on the right of
Figure 5. Avoid any mounting orientation that positions the top of the sensor at 90° from the
vertical position as shown on the left of Figure 5.

Flanged Sensors
Gaskets
The sensor requires a gasket at each of its connections to adjacent devices or piping. The
gasket material selected must be compatible with the process fluid and operating conditions.
Metallic or spiral-wound gaskets can damage the liner. Gaskets are required on each side of
a grounding ring. All other applications (including sensors with lining protectors or a
grounding electrode) require only one gasket on each end connection.
Figure 6. Flanged gasket placement
Flange Bolts
NOTE
Do not bolt one side at a time. Tighten each side simultaneously. Example:
1. Snug left
2. Snug right
3. Tighten left
4. Tighten right
Do not snug and tighten the upstream side and then snug and tighten the downstream side.
Failure to alternate between the upstream and downstream flanges when tightening bolts
may result in liner damage.
Suggested torque values by sensor line size and liner type are listed in Table 1 for ASME
B16.5 and Table 2 for EN flanges. Consult the factory if the flange rating of the sensor is not
listed. Tighten flange bolts on the upstream side of the sensor in the incremental sequence
shown in Figure 7 to 20% of the suggested torque values. Repeat the process on the
downstream side of the sensor. For sensors with more or less flange bolts, tighten the bolts
in a similar crosswise sequence. Repeat this entire tightening sequence at 40%, 60%, 80%,
and 100% of the suggested torque values or until the leak between the process and sensor
flanges stop.

If leakage has not stopped at the suggested torque values, the bolts can be tightened in
additional 10% increments until the joint stops leaking, or until the measured torque value
reaches the maximum torque value of the bolts. Practical consideration for the integrity of
the liner often leads the user to distinct torque values to stop leakage due to the unique
combinations of flanges, bolts, gaskets, and sensor liner material.
Check for leaks at the flanges after tightening the bolts. Failure to use the correct tightening
methods can result in severe damage. Sensors require a second tightening 24 hours after
the initial installation. Over time, sensor liner materials may deform under pressure.

Gaskets
The sensor requires a gasket at each of its connections to adjacent devices or piping. The gasket
material selected must be compatible with the process fluid and operating conditions. Metallic or
spiral-wound gaskets can damage the liner. Gaskets are required on each side of a
grounding ring. See Figure 8 below.

Alignment
1. On 1.5 through 8-inch (40 through 200 mm) line sizes. Rosemount strongly recommends
installing the alignment spacers provided to insure proper centering of the wafer sensor
between the process flanges. Sensor sizes of 0.15, 0.30, 0.5 and 1 in. (4 through 25
mm), do not require alignment spacers.
2. Insert studs for the bottom side of the sensor between the pipe flanges and center the
alignment spacer in the middle of the stud. See Figure 8 for the bolt hole locations
recommended for the spacers provided. Stud specifications are listed in Table 3.
3. Place the sensor between the flanges. Make sure that the alignment spacers are
properly centered on the studs. For vertical flow installations slide the oring over the stud
to keep the spacer in place. See Figure 8. To ensure the spacers match the flange size
and class rating for the process flanges see Table 4.
4. Insert the remaining studs, washers, and nuts.
5. Tighten to the torque specifications shown in Table 5. Do not overtighten the bolts or the
liner may be damaged.

NOTE
Sensor sizes of 0.15, 0.30, and 0.5 in. mount between AMSE 1/2-inch flanges. Using carbon
steel bolts on sensor sizes of 0.15, 0.30, 0.5 and 1 in. (15 and 25 mm), rather than the
required stainless steel bolts, will degrade the flow sensor measurement.
