environment], it must be assured that the device certification and installation
techniques are suitable for that particular environment.
Explosion hazard. Do not disconnect equipment when a flammable or combustible
atmosphere is present.
To prevent ignition of flammable or combustible atmospheres, disconnect power
before servicing circuits.
Do not connect a Rosemount 8732EM Transmitter to a non-Rosemount sensor that is
located in an explosive atmosphere.
Substitution of components may impair Intrinsic Safety.
Follow national, local, and plant standards to properly earth ground the transmitter and
sensor. The earth ground must be separate from the process reference ground.
Rosemount Magnetic Flowmeters ordered with non-standard paint options or
non-metallic labels may be subject to electrostatic discharge. To avoid electrostatic
charge build-up, do not rub the flowmeter with a dry cloth or clean with solvents.
The electronics may store energy after power is removed. Allow ten minutes for charge to
dissipate prior to removing electronics compartment cover.
Explosions could result in death or serious injury.
Verify the operating atmosphere of the sensor and transmitter is consistent with the
appropriate hazardous locations certifications.
Do not remove the transmitter cover in explosive atmospheres when the circuit is live.
Before connecting a HART-based communicator in an explosive atmosphere, make
sure the instruments in the loop are installed in accordance with intrinsically safe or
non-incendive field wiring practices.
Both transmitter covers must be fully engaged to meet explosion-proof requirements.

The flow sensor contains two magnetic coils located on opposite sides of the sensor. Two
electrodes, located perpendicular to the coils and opposite each other, make contact with the
liquid. The transmitter energizes the coils and creates a magnetic field. A conductive liquid
moving through the magnetic field generates an induced voltage at the electrodes. This voltage
is proportional to the flow velocity. The transmitter converts the voltage detected by the
electrodes into a flow reading.
1.2 Product recycling/disposal
Recycling of equipment and packaging should be taken into consideration and disposed of in

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 the installation is done safely and is consistent with the operating environment.
If installed in explosive atmospheres [hazardous areas, classified areas, or an “Ex”
environment], it must be assured that the device certification and installation
techniques are suitable for that particular environment.
Explosion hazard. Do not disconnect equipment when a flammable or combustible
atmosphere is present.
To prevent ignition of flammable or combustible atmospheres, disconnect power
before servicing circuits.
Do not connect a Rosemount 8732EM Transmitter to a non-Rosemount sensor that is
located in an explosive atmosphere.
Substitution of components may impair Intrinsic Safety.
Follow national, local, and plant standards to properly earth ground the transmitter
and sensor. The earth ground must be separate from the process reference ground.
Rosemount Magnetic Flowmeters ordered with non-standard paint options or
non-metallic labels may be subject to electrostatic discharge. To avoid electrostatic
charge build-up, do not rub the flowmeter with a dry cloth or clean with solvents.
NOTICE
The sensor liner is vulnerable to handling damage. Never place anything through the
sensor for the purpose of lifting or gaining leverage. Liner damage may render the sensor
inoperable.
Metallic or spiral-wound gaskets should not be used as they will damage the liner face of
the sensor. If spiral wound or metallic gaskets are required for the application, lining
protectors must be used. 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 specifications. Failure to
observe these instructions could result in severe damage to the sensor lining and possible
sensor replacement.
In cases where high voltage/high current are present near the meter installation, ensure
proper protection methods are followed to prevent stray voltage / current from passing
through the meter. Failure to adequately protect the meter could result in damage to the
transmitter and lead to meter failure.
Completely remove all electrical connections from both sensor and transmitter prior to
welding on the pipe. For maximum protection of the sensor, consider removing it from the
pipeline.

2.4 Pre-installation
Before installing the Rosemount 8732EM 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
2.5 Installation procedures
2.5.1 Transmitter installation
Installation of the Rosemount Magnetic flowmeter includes both detailed mechanical and
electrical installation procedures.
2.5.2 Identify options and configurations
Section 2: Installation
August 2015
The typical installation of the 8732EM includes a device power connection, a 4–20mA output
connection, and sensor coil and electrode connections. Other applications may require one or
more of the following configurations or options:
Pulse output
Discrete input/discrete output
HART multidrop configuration
Hardware switches
The 8732EM electronics stack is equipped with user-selectable hardware switches. These
switches set the alarm mode, internal/external analog power, internal/external pulse power, and
transmitter security. The standard configuration for these switches when shipped from the
factory are as follows:
Table 2-1. Standard Switch Configuration
Alarm Mode High
(1)
Internal/External Analog Power
Internal/External Pulse Power
Transmitter Security

Installation
In most cases, it will not be necessary to change the setting of the hardware switches. If the
switch settings need to be changed, follow the steps outlined in “Changing hardware switch
settings” on page 40).
Note
To prevent switch damage, use a non-metallic tool to move switch positions.

Section 2: Installation
August 2015
Identify any additional options and configurations that apply to the installation. Keep a list of
these options for consideration during the installation and configuration procedures.
2.5.3 Mechanical considerations
The mounting site for the 8732EM Transmitter should provide enough room for secure
mounting, easy access to conduit entries, full opening of the transmitter covers, and easy
readability of the Local Operator Interface (LOI) screen (if equipped).
For remote mount transmitter (8732EMRxxx) installations, a mounting bracket is provided for
use on a 2-in. pipe or a flat surface (see Figure 2-1).
Note
If the 8732EM is mounted separately from the sensor, it may not be subject to limitations that
might apply to the sensor.
Rotate integral mount transmitter housing
The transmitter housing can be rotated on the sensor in 90-degree increments by removing the
four mounting screws on the bottom of the housing. Do not rotate the housing more than
180 degrees in any one direction. Prior to tightening, be sure the mating surfaces are clean, the
O-ring is seated in the groove, and there is no gap between the housing and the sensor.

2.5.4 Electrical considerations
Before making any electrical connections to the 8732EM, consider national, local and plant
electrical installation requirements. Be sure to have the proper power supply, conduit, and other
accessories necessary to comply with these standards.
Both remotely and integrally mounted 8732EM Transmitters require external power so there
must be access to a suitable power source.

2.6 Handling and lifting
Handle all parts carefully to prevent damage. Whenever possible, transport the system
to the installation site in the original shipping container.
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.
Keep the shipping plugs in the conduit connections until you are ready to connect and
seal them.
The sensor should be supported by the pipeline. Pipe supports are recommended on
both the inlet and outlet sides of the sensor pipeline. There should be no additional
support attached to the sensor.
Additional safety recommendations for mechanical handling:
- Use proper PPE (Personal Protection Equipment) including safety glasses and
steel toed shoes).
- Do not drop the device from any height.
Do not lift the meter by holding the electronics housing or junction box.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.
If provided, use the lifting lugs on each flange to handle the Magnetic Flowmeter when
it is transported and lowered into place at the installation site. If lifting lugs are not
provided, the Magnetic Flowmeter must be supported with a lifting sling on each side
of the housing.

2.7 Mounting
2.7.1 Upstream/downstream piping
To ensure specified accuracy over widely varying process conditions, install the sensor with a
minimum of five straight pipe diameters upstream and two pipe diameters downstream from the
electrode plane (see
Figure 2-3. Upstream and Downstream Straight Run
Figure 2-3).
Reference Manual
00809-0100-4444, Rev AD
Installations with reduced upstream and downstream straight runs are possible. In reduced straight
run installations, the meter may not meet absolute accuracy specifications. Reported flow rates will
still be highly repeatable.
2.7.2 Flow direction
The sensor should be mounted so that the arrow points in the direction of flow. See Figure 2-4.

2.8 Sensor location
The sensor should be installed in a location that ensures it remains full during operation. Vertical
installation with upward process fluid flow keeps the cross-sectional area full, regardless of flow
rate. Horizontal installation should be restricted to low piping sections that are normally full.
Figure 2-5. Sensor Orientation
Section 2: Installation
August 2015
2.8.1 Electrode orientation
The electrodes in the sensor are properly oriented when the two measurement electrodes are in
the 3 and 9 o’clock positions or within 45 degrees from the horizontal, as shown on the left in
Figure 2-6. Avoid any mounting orientation that positions the top of the sensor at 90 degrees
from the vertical position as shown on the right in Figure 2-6.
Figure 2-6. Mounting Position
For hazardous location installations, refer to Appendix B for Installation Drawings 08732-2060
and 08732-2062 for sensor orientation pertaining to specific T-code compliance.

2.9 Sensor installation
2.9.1 Flanged sensors
Gaskets
The sensor requires a gasket at each process connection. The gasket material must be compatible with
the process fluid and operating conditions. Gaskets are required on each side of a grounding ring
(see
Figure 2-7). All other applications (including sensors with lining protectors or a grounding
electrode) require only one gasket on each process connection.
Note
Metallic or spiral-wound gaskets should not be used as they will damage the liner face of the
sensor. If spiral wound or metallic gaskets are required for the application, lining protectors
must be used.

2.9.2 Flange bolts
Note
Do not bolt one side at a time. Tighten both sides simultaneously. Example:
1. Snug upstream
2. Snug downstream
3. Tighten upstream
4. Tighten downstream
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 Ta b le 2 - 4 for ASME B16.5
flanges and Tab l e 2 - 5 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
downstream side of the sensor. For sensors with greater or fewer 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.
Figure 2-8 to 20% of the suggested torque values. Repeat the process on the
Section 2: Installation
August 2015
If leakage occurs 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. While under pressure, sensor materials may deform over
time and require a second tightening 24 hours after the initial installation.
