Rosemount 8732
SYSTEM DESCRIPTION The Rosemount
sensor and transmitter, and measures volumetric flow rate by detecting the
velocity of a conductive liquid that passes through a magnetic field.
There are four Rosemount magnetic flowmeter sensors:
• Flanged Rosemount 8705
• Flanged High-Signal Rosemount 8707
• Wafer-Style Rosemount 8711
• Sanitary Rosemount 8721
There are two Rosemount magnetic flowmeter transmitters:
• Rosemount 8712
• Rosemount 8732
The sensor is installed in-line with process piping — either vertically or
horizontally. Coils located on opposite sides of the sensor create a magnetic
field. Electrodes located perpendicular to the coils make contact with the
process fluid. A conductive liquid moving through the magnetic field
generates a voltage at the two electrodes that is proportional to the flow
velocity.
The transmitter drives the coils to generate a magnetic field, and electronical ly
conditions the voltage detected by the electrodes to provide a flow signal. T he
transmitter can be integrally or remotely mounted from the sensor.
This manual is designed to assist in the installation and ope ration of the
Rosemount 8732 Magnetic Flowmeter Transmitter and the Rosemount 8700
Series Magnetic Flowmeter Sensors.

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.
Emerson Process Management can supply lining protectors to prevent liner damage during
removal, installation, and excessive bolt torquing.

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, an d en vir onm en tal req uir eme nts
MECHANICAL CONSIDERATIONS
The mounting site for the 8732 transmitter should provide enough room for
secure mounting, easy access to conduit ports, full openin g of the transmitter
covers, and easy readability of the LOI screen (see Figure 2-1). The
transmitter should be mounted in a manner that prevent s moisture in conduit
from collecting in the transmitter.

Hardware
Jumpers/Switches
Conduit Ports and
Connections
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.
Both the sensor and transmitter junction boxes have ports for 1/2-inch NPT
conduit connections, with optional CM20 and PG 13.5 adapter connections
available. These connections should be made in accordance with national,
local or plant electrical codes. Unused ports should be sealed with metal
plugs and PTFE tape or other thread sealant. Connections should also be
made in accordance with area approval requ ire m en ts, see example s be low
for details. Proper electrical installation is necessary to prevent errors due to
electrical noise and interference. Separate conduits are not necessary for the
coil drive and signal cables connecting the transmitter to the sensor, but a
dedicated conduit line between each transmitter and sensor is required. A
shielded cable must be used.
Example 1: Installing flanged sensors into an IP68 area. Sensors must be
installed with IP68 cable glands and cable to maintain IP68 rating. Unused
conduit connections must be properly sealed to prevent water ingress. For
added protection, dielectric gel can be used to pot the sensor terminal block.
Consult technical document 00840-0100-4750 when installing meters into an
IP68 installation.
Example 2: Installing flowmeters into explosion proof/flameproof areas.
Conduit connections and conduit must be rated for use in the hazardous area
to maintain flowmeter approval rating. Consult Appendix B: of this manual for
installation requirements for hazardous areas.
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 . Do n ot run power cab les and outpu t signal cables in the same
conduit. For remote mount installations, run the coil drive and electrode
cables between the flowmeter and transmitter. Refer to Electrical
Considerations for wire type. Prepare the ends of the coil drive and electrode
cables as shown in Figure 2-2. Limit the unshielded wire length to 1-in. 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.

SENSOR CONNECTIONS This section covers the steps required to physically install the transmitter
including wiring and calibration.
Rosemount Sensors To connect the transmitter to a non-Rosemount sensor, refer to the
appropriate wiring diagram in “Universal Sensor Wiring Diagrams” on
page E-1. The calibration procedure listed is not required for use with
Rosemount sensors.

Wiring
Figure 2-7. Conduit Preparation

Flanged and wafer sensors have two conduit ports as shown in Figur e 2-7.
Either one may be used for both the coil drive and electrode cables. Use the
stainless steel plug that is provided to seal the unused conduit port. Use
PTFE tape or thread sealant appropriate for the installation when sealing the
conduit.
A single dedicated conduit run for the coil drive and electrode cables is
needed between a sensor and a remote transmitter. Bundled cables in a
single conduit are likely to create interference and noise problems in your
system. Use one set of cables per conduit run. See Figure 2-7 for proper
conduit installation diagram and Table 2-2 for recommended cable. For
integral and remote wiring diagrams refer to Figure 2-9.

Rosemount recommends using the combination signal and coil drive for N5,
E5 approved sensors for optimum performance.
Remote transmitter installations require equal lengths of signal and coil drive
cables. Integrally mounted transmitters are factory wired and do not require
interconnecting cables.
Lengths from 5 to 1,000 feet (1.5 to 300 meters) may be specified, and will be
shipped with the sensor.
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 sensor
and transmitter .
Prepare the ends of the coil drive and electrode cables as shown in Figure
2-8. Limit the unshielded wire length to 1-inch on both the electrode and coil
drive cables.
NOTE
Excessive lead length or failure to connect cable shields ca n create electrical
noise resulting in unstable meter readings.

This section covers basic operation, software functionality, and basic
configuration procedures for the Rosemount 8732E Magnetic Flowmeter
Transmitter with Profibus PA. For more information about the Profibus PA
technology and the function blocks used in the transmitter, refer to
Appendix F: Physical Block and Appendix G.
Calibration Rosemount sensors are wet calibrated at the factory. They do not need
further calibration during installation.
Each Profibus PA configuration tool or host device has a different way of
displaying and performing configurations. Some will use Device Descriptions
(DD) and DD Methods to make configuring and displaying data consistent
across host platforms. There is no requirement that a configuration tool or
host support these features. This section describes how to reconfigure the
device manually.
QUICK START-UP Once the magnetic flowmeter system is installed and communication is
established, configuration of the transmitter must b e completed. The st andard
transmitter configuration, without Option Code C1, Custom Configuration, is
shipped with the following parameters:
Engineering Units: ft/s
Sensor Size: 3-in.
Sensor Calibration Number: 100000501000000
Sensor
Calibration Number
A unique sensor calibration number, imprinted on the sensor tag, enables any
Rosemount sensor to be used with any Rosemount transmitter without further
calibration. Rosemount flow lab tests determine individual sensor output
characteristics. The characteristics are identified by a 16-digit calibration
number . In a Profibus PA environment, the 8732E can be configured using an
8732E Profibus P A LOI or a Simatic PDM. Please see Section 4 for 8732E PA
LOI and PDM information.

The calibration number is more than a correction factor, or K- factor, for the
sensor. The first five digits represent the low frequency gain. The ninth
through thirteenth digits represent the high frequency ga in. Both nu mbers are
normalized from an ideal number of 10000. Standard configurations use the
low frequency gain, but in noisy applications it may be worthwhile to switch to
the higher frequency. An additional transmitter procedure, called Auto Zero, is
recommended to perform at the higher coil drive frequency. The seventh and
eighth digits represent the zero offset at both frequencies where the nominal
value is 50. Empty pipe functionality is a transmitter feature that is controlled
by a parameter in the transducer block. To turn off this feature, see
Appendix C.
ASSIGNING DEVICE T AG AND NODE ADDRESS
The 8732E Magnetic Flowmeter Tr ansmitter is shipped with a blank tag. The
device is shipped with a default address of 126.
If the tag or address needs to be changed, use the features of the
configuration tool. The tools do the following:
• Change the tag to a new value.
• Change the address to a new address.

AI Block The Analog Input (AI) function block processes field device measurements
and makes them available to the master. The output value from the AI block is
in engineering units and contains a status indi cating the quality of the
measurement. The measuring device may have several measurements or
derived values available in different channels. Use the channel number to
define the variable that the AI block processes. The 8732E transmitter only

PV The process variables (PV) measure flow in several ways that reflect your
needs and the configuration of your flowmeter. When commissioning a
flowmeter, review each process variable, its function and output, and take
corrective action if necessary before using the flowmeter in a
process application
PV Value – The actual measured flow rate in the line. Use the Process
Variable Units function to select the units for your application.
PV Status – The status of the pr ocess variable. This indicates whether the
reported flow rate is “good”, “uncertain”, or “bad”.
PV Value The PV Value shows the current measured flow rate.
PV Status The PV Status shows the health of the PV Value.
Good - The PV Value is valid an d th e flo wmeter system is operating normally.
Uncertain - The PV Value is being reported, but a condition exists that is
potentially compromising the measurement. This condition could be caused
by a problem with the flowmeter or the process.
Bad - A problem exists with the flowmeter system that has resulted in a
potentially faulty flow measurement. Consult status and diagnostic
information to identify the problem.
BASIC SETUP The basic configuration functions of the Rosemount 8732 must be set for all
applications of the transmitter in a magnetic flowmeter system. If your

Upper Range Value This parameter set the flow rate in engineering units that corresponds to
100% flow. This parameter is configured in the Transducer Block.
The Upper Range Value can be set for both forward or reverse flow rates.
Flow in the forward direction is represented by positive values and flow in the
reverse direction is represented by negative values. The URV can be any
value from –43.3 ft/s to +43.3 ft/s (-13.2 m/s to +13.2 m/s), as long as it is at
least 1 ft/s (0.3 m/s) from the lower range value (LRV). The URV can be set to
a value less than the lower range value.
NOTE
Line size and density must be selected prior to configuration of URV and LRV .
Lower Range Value This parameter sets the flow rate in engineering units that correspo nds to 0%
flow. This pa rameter is configured in the Transducer Block.
Set the lower range value (LRV) to change the size of the range (or span)
between the URV and LRV. Under normal circumstances, the LRV should be
set to a value near the minimum expected flow rate to maximize resolution.
The LRV must be between –43.3 ft/s to +43.3 ft/s (-13.2 m/s to +13.2 m/s).
NOTE
Line size and density must be selected prior to configuration of URV and LR V.
The minimum allowable span between the URV and LRV is 1 ft/s (0.3 m/s).
Do not set the LRV within 1 ft/s (0.3 m/s) of the URV. For example, if the URV
is set to 15.67 ft/s (4.8 m/s) and if the desired URV is greater than the LRV,
then the highest allowable LRV setting would be 14.67 ft/s (4.5 m/s). If the
desired URV is less than the LRV, then the lowest allowable LRV would be
16.67 ft/s (5.1 m/s).
Calibration Number The sensor calibration number is a 16-digit number used to identify sensors
calibrated at the Rosemount factory. The calibration number is also printed
inside the sensor terminal block or on the sensor name plate. The number
provides detailed calibration information to the Rosemount 8732. To function
properly within accuracy specifications, the number stored in the transmitter
must match the calibration number on the sensor exactly. This parame te r is
configured in the Transducer Block.
NOTE
Sensors from manufacturers other than Rose m ou nt Inc. can als o be
calibrated at the Rosemount factory. Check the sensor for Rosemount
calibration tags to determine if a 16-digit sensor calibration number exists for
your sensor.

NOTE
Be sure the calibration number reflects a calibration to a Rosemount
reference transmitter. If the calibration number was generated by a means
other than a certified Rosemount flow lab, accuracy of the system may be
compromised.
If your sensor is not a Rosemount sensor and was not calibrated at the
Rosemount factory, contact your Rosemount representative for assistance.
If your sensor is imprinted with an eight-digit number or a k-factor, check in
the sensor wiring compartment for the sixteen-digit calibration number. If
there is no serial number, contact the factory for a proper conversion.
