STEP 1: PRE-INSTALLATION
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 LOI
screen (see Figure 1). The transmitter should be mounted in an
upright position.
If the Rosemount 8732 is mounted separately from the flowtube, it
is not subject to limitations that might apply to the flowtube.
WARNING
The flowtube liner is vulnerable to handling damage. Never place
anything through the flowtube for the purpose of lifting or gaining
leverage. Liner damage can render the flowtube useless.
To avoid possible damage to the flowtube 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 flowtube ends are often used for protection.
Correct flange bolt tightening is crucial for proper flowtube 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 flowtube lining and possible flowtube
replacement.

Environmental Considerations
To ensure maximum transmitter life, avoid excessive heat and
vibration. Typical problem areas:
• 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 provides easy
access for configuration or service.
Both remotely and integrally mounted Rosemount 8732 transmitters
require external power and 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 plate to the pipe using the mounting hardware.
2. Attach the Rosemount 8732 to the mounting plate using the
mounting screws.

Identify Options and Configurations
The standard application of the 8732 includes a 4–20 mA output and
control of the flowtube coils. Other applications may require one or
more of the following configurations or options:
• Multidrop Communications
• Auxiliary Output
• Pulse Output
Additional options may apply. Be sure to identify those options and
configurations that apply to your situation, and keep a list of them
nearby for consideration during the installation and configuration
procedures.
Hardware Jumpers/Switches
The 8732 electronics board is equipped with
three user-selectable hardware switches. These switches set the
Failure Alarm Mode, Internal/External Analog Power, and Transmitter
Security. The standard configuration for these switches when shipped
from the factory are as follows:
Changing Hardware Switch Settings
In most cases, it is not necessary to change the setting of the
hardware switches. If you need to change the switch settings,
complete the steps outlined in the manual.
Failure Alarm Mode: HIGH
Internal/External Analog Power: INTERNAL
Transmitter Security: OFF

Electrical Considerations
Before making any electrical connections to the Rosemount 8732,
consider the following standards and be sure to have the proper power
supply, conduit, and other accessories.
Rotate Transmitter Housing
The electronics housing can be rotated on the flowtube 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 flowtube.
STEP 2: HANDLING
Handle all parts carefully to prevent damage. Whenever possible,
transport the system to the installation site in the original shipping
containers. Teflon®-lined flowtubes are shipped with end covers that
protect it from both mechanical damage and normal unrestrained
distortion. Remove the end covers just before installation.

STEP 3: MOUNTING
Upstream/Downstream Piping
To ensure specification accuracy over widely varying process
conditions, install the flowtube a minimum of five straight pipe
diameters upstream and two pipe diameters downstream from the
electrode plane (see Figure 3).
Flow Direction
The flowtube should be mounted so the FORWARD end of the flow
arrow, shown on the flowtube identification tag, points in the direction
of flow through the tube.
Flowtube Orientation
The flowtube should be installed in a position that ensures the
flowtube 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. In these cases, orient the
electrode plane to within 45 degrees of horizontal.

The electrodes in the Rosemount 8705 flowtube are properly
orientated when the two measurement electrodes are in the 3 and 9
o’clock positions, as shown on the right of Figure 4.
The electrodes in the Rosemount 8711 are properly orientated when
the top of the flowtube is either vertical or horizontal, as shown in
Figure 5. Avoid any mounting orientation that positions the top of the
flowtube at 45° from the vertical or horizontal position.

STEP 4: INSTALLATION (FLANGED FLOWTUBE)
Gaskets
The flowtube 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 the
grounding ring. All other applications (including flowtubes with lining
protectors or a grounding electrode) require only one gasket on each
end connection.
Flange Bolts
Suggested torque values by flowtube line size and liner type are listed
in Table 1 for ASME B16.5 (ANSI) and Table 2 for DIN flanges.
Consult the factory if the flange rating of the flowtube is not listed.
Tighten flange bolts on the upstream side of the flowtube in the
incremental sequence shown in Figure 6 to 20% of the suggested
torque values. Repeat the process on the downstream side of the
flowtube. For flowtubes 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 flowtube 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 flowtube
liner material.
Check for leaks at the flanges after tightening the bolts. Failure to use
the correct tightening methods can result in severe damage.
Flowtubes require a second tightening 24 hours after the initial
installation. Over time, flowtube liner materials may deform under

Alignment and Bolting
1. On 11/2- through 8-inch (40 through 200 mm) line sizes, place
centering rings over each end of the flowtube. The smaller line
sizes, 0.15- through 1-inch (4 through 25 mm), do not require
centering rings. On the 4- and 6-inch PN 10–16, insert the flowtube
with rings first and then insert the studs. The slots on this ring
scenario are located on the inside of the ring.
2. Insert studs for the bottom side of the flowtube between the pipe
flanges. Stud specifications are listed in Table 3. Using carbon
steel bolts on smaller line sizes, 0.15- through 1-inch
(4 through 25 mm), rather than the required stainless steel
bolts, will degrade performance.
3. Place the flowtube between the flanges. Make sure that the
centering rings are properly placed in the studs. The studs should
be aligned with the markings on the rings that correspond to the
flange you are using.
4. Insert the remaining studs, washers, and nuts.
5. Tighten to the torque specifications shown in Table 1. Do not
overtighten the bolts or the liner may be damaged.

Gaskets
The flowtube 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. Gaskets are supplied
between the IDF fitting and the process connection fitting, such as a
Tri-Clamp fitting, on all Rosemount 8721 Sanitary flowtubes except
when the process connection fittings are not supplied and the only
connection type is an IDF fitting.
Alignment and Bolting
Standard plant practices should be followed when installing a
magmeter with sanitary fittings. Unique torque values and bolting
techniques are not required.

STEP 5: GROUNDING
Use Table 5 to determine which grounding option to follow for proper
installation. The flowtube case should always be earth grounded in
accordance with national and local electrical codes. Failure to do so
may impair the protection provided by the equipment. The Internal
Ground Connection (Protective Ground Connection) located in side
the junction box is the Internal Ground Connection screw. This screw
is identified by the ground symbol.

Conduit Ports and Connections
Both the flowtube and transmitter junction boxes have ports for ¾-inch
NPT conduit connections. These connections should be made in
accordance with local or plant electrical codes. Unused ports should
be sealed with metal plugs. Proper electrical installation is necessary
to prevent errors due to electrical noise and interference. Separate
conduits are not necessary for the two cables, but a dedicated conduit
line between each transmitter and flowtube is required. Shielded cable
must be used for best results in electrically noisy environments.
Conduit Cables
Run the appropriate size cable through the conduit connections in your
magnetic flowmeter system. Run the power cable from the power
source to the transmitter. Run the coil drive and electrode cables
between the flowmeter and transmitter. Prepare the ends of the coil
drive and electrode cables as shown in Figure 13. Limit the unshielded
wire length to 1-inch on both the electrode and coil drive cables.
Excessive lead length or failure to connect cable shields can create
electrical noise resulting in unstable meter readings.

Step 6.1 Transmitter Coil Input
This wiring section covers supplying power to the flowtube coils
through the transmitter. The transmitter coil input power sends a
pulsed DC frequency to the flowtube.
Wire the transmitter according to local electrical requirements. Ground
the transmitter cage via the threaded conduit connection. For ac power
applications, connect ac Neutral to terminal N and connect ac Line to
terminal L1. For dc power applications, properly connect the positive
and negative terminals. Units powered by 15-50 V dc power supply
may draw up to 1 amp of current. In addition, follow the supply wire
and disconnect requirements below:
