NOTICE
This document provides basic installation guidelines for the Rosemount® 8750W Magnetic
Flowmeter System. For comprehensive instructions, for detailed configuration, diagnostics,
maintenance, service, installation or troubleshooting, refer to the Rosemount 8750W
reference manual (document number 00809-0100-4750 Rev. BA). The manual and this QSG
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
operating environment.
Do not connect a Rosemount transmitter to a non-Rosemount sensor that is located in an
explosive atmosphere.
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 frequent removal is anticipated, take precautions to protect the liner ends. Short spool
pieces attached to the sensor ends are often used for protection.
Rosemount Magnetic Flowmeters ordered with non-standard paint options 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.
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.

Quick Start Guide
Step 1: Pre-installation
Before installing the Rosemount 8750W Flowmeter, 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 8750W 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 2).
If the Rosemount 8750W transmitter is mounted separately from the sensor, it
may not be subject to the same limitations that apply to the sensor.

Environmental considerations
To ensure maximum transmitter life, avoid extreme temperature and excessive
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 provide easy access for
configuration or service.
Both remotely and integrally mounted Rosemount 8750W transmitters require
external power so there must be access to a suitable power source.
Installation procedures
Rosemount 8750W 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 8750W transmitter to the mounting bracket using the
mounting screws.
Identify options and configurations
The standard application of the 8750W includes a 4–20 mA output and control of
the sensor coils and electrodes. Other applications may require one or more of
the following configurations or options:
HART Multidrop Configuration
Discrete Output
Discrete Input
Pulse Output
Be sure to identify any additional options and configurations that apply to the
installation. Keep a list of these options nearby for consideration during the
installation and configuration procedures.

Quick Start Guide
Hardware jumpers/switches
The 8750W electronics board is equipped with user-selectable hardware switches
depending on the transmitter model ordered. These switches set the Failure
Alarm Mode, Internal/External Analog Power, Internal/External Pulse Power and
Transmitter Security. The standard configuration for these switches when
shipped from the factory is as follows:
Failure Alarm Mode: HIGH
Internal/External Analog Power: INTERNAL
Internal/External Pulse Power: EXTERNAL (Field Mount only)
Transmitter Security: OFF
Changing hardware switch settings
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
the manual.
Use a non-metallic tool to move switch positions.
Electrical considerations
Before making any electrical connections to the Rosemount 8750W, 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.
February 2014
Rotate transmitter housing
The Field Mount transmitter housing can be rotated on the sensor in 90°
increments by removing the four mounting bolts on the bottom of the housing.
Do not rotate the housing more than 180 ° 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.

Step 2: Handling
Handle all parts carefully to prevent damage. Whenever possible, transport the
system to the installation site in the original shipping containers. Rosemount flow
sensors are shipped with end covers that protect it from mechanical damage. For
PTFE lined sensors the cover also prevents normal liner relaxation. Remove the
end covers just before installation.

Quick Start Guide
Step 3: Mounting
Upstream/downstream piping
To 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 4. Upstream and downstream straight pipe diameters
5 Pipe Diameters
Flow
Installations with reduced upstream and downstream straight runs are possible.
In reduced straight run installations, absolute performance may shift. Reported
flow rates will still be highly repeatable.
The sensor should be mounted so the FORWARD end of the flow arrow points in
the direction of flow through the sensor (see
Figure 5).
Figure 4).

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.

Mounting position
The electrodes in the sensor are properly orientated when the two measurement
electrodes are in the 3 and 9 o’clock position or within 45 ° from the vertical, as
shown on the right of

Step 4: Installation
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. 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.
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.

Quick Start Guide
Flange bolts
Do not bolt one side at a time. Tighten each side 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
page 12. 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
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.

Step 6: Wiring
This wiring section covers the connection between the transmitter and sensor,
the 4-20 mA loop, and supplying power to the transmitter. Follow the conduit
information, cable requirements, and disconnect requirements in the sections
below.
Conduit ports and connections
Both the sensor and transmitter junction boxes have ports for 1/2-inch NPT
conduit connections or optional M20 connection is available. These connections
should be made in accordance with national, local, and 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 coil drive and electrode cables, but a dedicated
conduit line between each transmitter and sensor is required. Shielded cable
must be used for best results in electrically noisy environments. When preparing
all wire connections, remove only the insulation required to fit the wire
completely under the terminal connection. Removal of excessive insulation may
result in an unwanted electrical short to the transmitter housing or other wire
connections. For flanged sensors installed into an application requiring IP68
protection, sealed cable glands, conduit, and conduit plugs that meet IP68
ratings are required. Option Codes R05, R10, R15, R20, R25, and R30 provide a
pre-wired potted and sealed junction box as additional protection to prevent the
ingress of water. These options still require the use of sealed conduits to meet
IP68 protection requirements.
Conduit requirements
A single dedicated conduit run for the coil drive and electrode cable is needed
between the sensor and the remote transmitter. See
in a single conduit are likely to create interference and noise problems in the
system.
Electrode cables should not be run together and should not be in the same cable
ray with power cables.
Output cables should not be run together with power cables.
Select conduit size appropriate to feed cables through to the flowmeter.

Quick Start Guide
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
sensor and transmitter.
Installed signal wiring should not be run together and should not be in the
same cable tray as AC or DC power wiring.
Device must be properly grounded according to national and local electric
codes.
Rosemount combination cable part number 08732-0753-1003 (ft) or
08732-0753-2004 (m) is required to be used to meet EMC requirements.
Transmitter to sensor wiring
The transmitter can be integral to the sensor or remotely mounted following the
wiring instructions.
Remote mount cable requirements and preparation
For installations using the individual coil drive and electrode cable, lengths should
be limited to less than 1,000 feet (300 meters). Equal length cable is required for
each. See
For installations using the combination coil drive and electrode cable, lengths
should be limited to less than 330 feet (100 meters). See
Prepare the ends of the coil drive and electrode cables as shown in
Limit the unshielded wire length to 1-inch on both the coil drive and electrode
cables. Any unsheathed wire should be wrapped with proper insulation. Excessive
lead length or failure to connect cable shields can create electrical noise resulting
in unstable meter readings.

Connecting the 4–20 mA analog signal
Cabling considerations
If possible, use individually shielded twisted pair cable, either in single pair or
multi-pair varieties. Unshielded cables may be used for short distances, provided
ambient noise and cross-talk will not adversely impact communication. The
minimum conductor size is 0.51mm diameter (#24 AWG) for cable runs less than
1,500 meters (@ 5,000 ft.) and 0.81mm diameter (#20 AWG) for longer
distances. Resistance in the loop must be 1000 ohms or less.
The 4–20 mA analog output loop signal may be powered internally or externally.
The default position of the internal/external analog power switch is in the internal
position. The user-selectable power supply switch is located on the electronics
board.

Internal power source
The 4–20 mA analog signal loop is powered from the transmitter itself.
External power source
The 4–20 mA analog signal loop is powered from an external power source. HART
multidrop installations require a 10–30 VDC external analog power source.
Note:
If a HART Field Communicator or control system will be used, it must be connected across a
minimum of 250 ohms resistance in the loop.
To connect any of the other output options (pulse output and/or discrete
input/output), consult the comprehensive product manual.

Supply wire requirements
Use 10 - 18 AWG wire rated for the proper temperature of the application. For
wire 10 - 14 AWG use lugs or other appropriate connectors. For connections in
ambient temperatures above 140 °F (60 °C), use a wire rated for 176 °F (80 °C). For
ambient temperatures greater than 176 °F (80 °C), use a wire rated for 230 °F (110
°C). For DC powered transmitters with extended cable lengths, verify that there is
a minimum of 12 VDC at the terminals of the transmitter. Disconnects
Connect the device through an external disconnect or circuit breaker.
Installation category
The installation category for the 8750W is (Overvoltage) Category II.
Overcurrent protection
The Rosemount 8750W flowmeter transmitter requires overcurrent protection of
the supply lines. Maximum ratings of overcurrent devices are shown in
Table 8.

Field mount power supply
For AC power applications (90-250 VAC, 50-60 Hz), connect AC Neutral to
terminal 9 (AC N/L2) and connect AC Line to terminal 10 (AC/L1). For DC power
applications, connect negative to terminal 9 (DC -) and positive to terminal 10
(DC +). Units powered by 12-42 VDC power supply may draw up to 1 amp of
current. See
Figure 24. Field mount transmitter power connections
Figure 24 for terminal block connections.

Wall mount power supply
For AC power applications (90-250 VAC, 50-60 Hz), connect AC Neutral to
terminal N and connect AC Line to terminal L1. For DC power applications,
connect negative to terminal N (DC -) and positive to terminal L1 (DC +). Ground
the transmitter cage via the grounding stud located on the bottom of the
transmitter housing. Units powered by 12-42 VDC power supply may draw up to
1 amp of current. See

Field mount cover jam screw
For transmitter housings shipped with a cover jam screw, the screw should be
properly installed once the transmitter has been wired and powered up. Follow
these steps to install the cover jam screw:
1. Verify that the cover jam screw is completely threaded into the housing.
2. Install the transmitter housing cover and verify that the cover is tight against
the housing.
3. Using a 2.5 mm hex wrench, loosen the jam screw until it contacts the
transmitter cover.

4. Turn the jam screw an additional
(Note: Application of excessive torque may strip the threads.)
5. Verify that the cover cannot be removed.
/2 turn counterclockwise to secure the cover.

Step 7: Basic configuration
Once the magnetic flowmeter is installed and power has been supplied, the
transmitter must be configured through the basic setup. These parameters can
be configured through either a local operator interface or a HART communication
device. A table of all the parameters begins on
advanced functions are included in the comprehensive product manual.
page 29. Descriptions of the more
Basic setup
Tag
Tag is the quickest and shortest way of identifying and distinguishing between
transmitters. Transmitters can be tagged according to the requirements of your
application. The tag may be up to eight characters long.
Flow units (PV)
The flow rate units variable specifies the format in which the flow rate will be
displayed. Units should be selected to meet your particular metering needs.
URV (Upper Range Value)
The upper range value (URV) sets the 20 mA point for the analog output. This
value is typically set to full-scale flow. The units that appear will be the same as
those selected under the units parameter. The URV may be set between
–39.3 ft/s to 39.3 ft/s (–12 m/s to 12 m/s). There must be at least 1 ft/s (0.3 m/s)
span between the URV and LRV.
February 2014
LRV (Lower Range Value)
Reset the lower range value (LRV) sets the 4 mA point for the analog output. This
value is typically set to zero flow. The units that appear will be the same as those
selected under the units parameter. The LRV may be set between
–39.3 ft/s to 39.3 ft/s (–12 m/s to 12 m/s). There must be at least 1 ft/s (0.3 m/s)
span between the URV and LRV.
Line size
The line size (sensor size) must be set to match the actual sensor connected to the
transmitter. The size must be specified in inches.
Calibration number
The sensor calibration number is a 16-digit number generated at the Rosemount
factory during flow calibration and is unique to each sensor.
Local operator interface
To activate the optional Local Operator Interface (LOI), press the DOWN arrow
two times. Use the UP, DOWN, LEFT, and RIGHT arrows to navigate the menu
structure. The display can be locked to prevent unintentional configuration
changed. The display lock can be activated through a HART communication
device, or by holding the UP arrow for 10 seconds. When the display lock is
activated, DL will appear in the lower right hand corner of the display. To
deactivate the display lock (DL), hold the UP arrow for 10 seconds. Once
deactivated, the DL will no longer appear in the lower right hand corner of the
display.
