This section covers the steps required to physically install the magnetic
sensor. Instructions and procedures in this section may require special
precautions to ensure the safety of the personnel performing the operations.
Please refer to the following safety messages before performing any
operation in this section.
Rosemount 8700 Series
SAFETY MESSAGES This symbol is used throughout this manual to indicate that special attention
to warning information is required.
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 hazardous area approval.
Do not connect a Rosemount transmitter to a non-Rosemount sensor that is located in an
explosive atmosphere.
www.rosemount.com
Rosemount 8700 Series
Explosions could result in death or serious injury:
Installation of this transmitter in an explosive environment must be in accordance with the
appropriate local, national, and international standards, codes, and practices. Please review
the approvals section of this reference manual for any restrictions associated with a safe
installation.
Electrical shock can result in death or serious injury
Avoid contact with the leads and terminals. High voltage that may be present on leads can
cause electrical shock.
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.

SENSOR HANDLING 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.
Flanged sensors with a lifting lug on each flange make the sensor easier to
handle when it is transported and lowered into place at the installation site.
Flanged sensors that do not have lugs must be supported with a lifting sling
on each side of the housing.
Figure 2-1 shows sensors correctly supported for handling and installation.
Notice the plywood end pieces are still in place to protect the sensor liner
during transportation.

SENSOR MOUNTING Physical mounting of a sensor is similar to installing a typical section of pipe.
Conventional tools, equipment, and accessories (bolts, gaskets, and
grounding hardware) are required.
Upstream/Downstream
Piping
Figure 2-2. Upstream and
Downstream
Straight Pipe Diameters
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 2-2).
Sensor Orientation The sensor should be installed in a position that ensures the sensor remains
full during operation. Figures 2-3, 2-4, and 2-5 show the proper sensor
orientation for the most common installations. The following orientations
ensure that the electrodes are in the optimum plane to minimize the ef fects of
entrapped gas.
Vertical installation allows upward process fluid flow and is generally
preferred. Upward flow keeps the cross-sectional area full, regardless
of flow rate. Orientation of the electrode plane is unimportant in vertical
installations. As illustrated in Figures 2-3 and 2-4, avoid downward flows
where back pressure does not ensure that the se nsor remains full at all times.
Figure 2-3. Vertical Sensor
Orientation
Installations with reduced straight runs from 0 to five pipe diameters are
possible. In reduced straight pipe run installations, performance will shift to as
much as 0.5% of rate. Reported flow rates will still be highly repeatable.

Figure 2-4. Incline or Decline
Orientation
Rosemount 8700 Series
Horizontal installation should be restricted to low piping sections that are
normally full. Orient the electrode plane to within 45 degrees of horizontal in
horizontal installations. A deviation of more than 45 degrees of horizontal
would place an electrode at or near the top of the sensor thereby making it
more susceptible to insulation by air or entrapped gas at the top of the
sensor.
Figure 2-5. Horizontal Sensor
Orientation

Rosemount 8700 Series
The electrodes in the Rosemount 8711 are properly oriented when the top of
the sensor is either vertical or horizontal, as shown in Figure 2-6. Avoid any
mounting orientation that positions the top of the sensor at 45 degrees from
the vertical or horizontal position.

INSTALLATION (FLANGED SENSOR)
The following section should be used as a guide in the installation of the
flange-type Rosemount 8705 and Rosemount 8707 High-Signal Sensors.
Refer to page 2-10 for installation of the wafer-type Rosemount 8711 Sensor.
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. If the gaskets will be removed frequently, protect the liner ends. All other
applications (including sensors with lining protectors or a grounding electrode)
require only one gasket on each end connection, as shown in Figure 2-8. If
grounding rings are used, gaskets are required on each side of the groundin g
ring, as shown in Figure 2-9.

Rings
Flange Bolts Suggested torque values by sensor line size and liner type are listed in Table
2-1 on page 2-8 for ASME B16.5 (ANSI) flanges and Table 2-2 and Table 2-3
for DIN flanges. Consult the factory for other flange ratings. Tighten flange
bolts in the incremental sequence as shown in Figure 2- 10. See Table 2-1 and
Table 2-2 for bolt sizes and hole diameters.
2-7
Rosemount 8700 Series
See ”Safety Messages” on pages 2-1 and 2-2 for complete warning information.
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 a nd downstream
flanges when tightening bolts may result in liner damage.
Always check for leaks at the flanges after tightening the flange bolts. Failure
to use the correct flange bolt tightening methods can result in severe dam age.
All sensors require a second torquing 24 hours after initial flange bolt
tightening.

(1) Derated available with PTFE lining only.
For sensors with ANSI 600# full rated, 900#, 1500#, and 2500# flanges, the
liner is protected from over-compression by the flange design. Standard
flange torque specifications as determined by ANSI and ASME should be
followed. No special precaution is required to prevent liner damage caused by
over torquing. Bolt tightening procedures laid out in this Quick Installation
Guide must still be followed.

To prevent liner damage on any magnetic flowmeter, a flat gasket must be
used. For optimum results on meters with high pressure flanges (ANSI 600#
or above), it is recommended that a flat full face gasket be used.
Under NO circumstances should a spiral wound or flexitallic gasket be used
as this will damage the liner sealing surface.

INSTALLATION (WAFER SENSOR)
The following section should be used as a guide in the installation of the
Rosemount 8711 Sensor. Refer to page 2-7 for installation of the flange-type
Rosemount 8705 and 8707 High-Signal sensor.
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. If the gaskets will be removed frequently, protect the
liner ends. If grounding rings are used, a gasket is required on each side of
the grounding ring.
Alignment and Bolting
1. On 11/2 - through 8-in. (40 through 200 mm) line sizes, place centering
rings over each end of the sensor. The smaller line sizes, 0.15through 1-in. (4 through 25 mm), do not require centering rings.
2. Insert studs for the bottom side of the sensor between the pipe
flanges. Stud specifications are listed in Table 2-4. Using carbon
steel bolts on smaller line sizes, 0.15- through 1-in.
(4 through 25 mm), rather than the required stainless steel bolts,
will degrade performance.

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.
Always check for leaks at the flanges after tightening the flange
bolts. All sensors require a second torquing 24 hours after initial flange bolt
tightening.

PROCESS LEAK PROTECTION (OPTIONAL)
Standard Housing
Configuration
The Rosemount 8705 and 8707 High-Signal Sensor housing is fabricated
from carbon steel to perform two separate functions. First, it provides
shielding for the sensor magnetics so that external disturbances cannot
interfere with the magnetic field and thus affect the flow measu re m en t.
Second, it provides the physical protection to the coils and other internal
components from contamination and physical d amage that might occur in an
industrial environment. The housing is completely welded and gasket-free.
The three housing configurations are identified by the W0, W1, or W3 in the
model number option code when ordering. Below are brief description s of
each housing configuration, which are followed by a more detailed overview.
• Code W0 — sealed, welded coil housing (standard configuration)
• Code W1 — sealed, welded coil housing with a relief valve capable of
venting fugitive emissions to a safe location (additional plumbing from
the sensor to a safe area, installed by the user, is required to vent
properly)
• Code W3 — sealed, welded coil housing with separate electrode
compartments capable of venting fugitive emissions (additional
plumbing from the sensor to a safe area, installed by the user, is
required to vent properly)
The standard housing configuration is identified by a code W0 in the model
number. This configuration does not provide separate electrode
compartments with external electrode access. In the even t of a pr oc es s leak,
these models will not protect the coils or other sensitive areas around the
sensor from exposure to the pressure fluid (Figure 2-13).

Relief Valves The first optional configuration, identified by the W1 in the model number
option code, uses a completely welded coil housing. This configuration does
not provide separate electrode compartments with external electrode access.
This optional housing configuration provides a relief valve in the housing to
prevent possible overpressuring, caused by damage to the lining or other
situations that might allow process pressure to enter the housing. The relief
valve will vent when the pressure inside the sensor housing exceeds five psi.
Additional piping (provided by the user) may be connected to this relief valve
to drain any process leakage to safe containment (see Figure 2-14).

Containment
The second optional configuration, identified as option code W3 in the model
number, divides the coil housing into three compartments: one for each
electrode and one for the coils. Should a damaged liner or electrode fault
allow process fluid to migrate behind the electrode seals, the fluid is cont ained
in the electrode compartment. The sealed electrode compartment prevents
the process fluid from entering the coil compartment wh er e it woul d dam ag e
the coils and other internal components.
The electrode compartments are designed to contain the process fluid at full
line pressure. An O-ring sealed cover provides access to each of the
electrode compartments from outside the sensor; drainports are provided in
each cover for the removal of fluid.
NOTE
The electrode compartment could contain full line pressure and it must be
depressurized before the cover is removed.

Both the sensor and transmitter junction boxes have ports for 1/2-in. 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 require m ents, see exam ples below
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.

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 2-16. 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.

Electrical Considerations Before making any electri cal connections to the Rosemount transmitter,
consider the following standards and be sure to have the proper power
supply, conduit, and other accessories. 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.
Transmitter Input Power
The Rosemount transmitter is designed to be powered b y 90 -25 0 Vac, 50–60
Hz or 12–42 Vdc. The eighth digit in the transmitter model number design ates
the appropriate power supply requirement.
Model Number Power Supply Requirement
1 90-250 Vac
2 12-42 Vdc
Supply Wire Temperature Rating
Use 14 to 18 AWG wire rated for the proper temperatu re of the application.
For connections in ambient temperatures above 140 °F (60 °C), use a wire
rated for 176 °F (80 °C). For ambients greater than 176 °F (80 °C), use a
wire rated for 230 °F (110 °C). For DC powered transmitters with extended
power 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.
Clearly label the disconnect or circuit breaker and locate it near the
transmitter.
Consult the applicable Rosemount Transmitter Documentation for detailed
transmitter installation instructions.

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.

Flanged and wafer sensors have two conduit ports as shown in Figur e 2-17.
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 2-17 for proper
conduit installation diagram and Table 2-6 for recommended cable. For
integral and remote wiring diagrams refer to Figure 2-18.

the technology and the function blocks used in the sensor, refer to
Appendix A: Reference Data and Appendix C: Field-Removable Electrodes.
CALIBRATION Rosemount sensor are wet calibrated at the factory. They do not need further
calibration during installation.
GROUNDING Process grounding the sensor is one of the most important details of sensor
installation. Proper process grounding ensures that th e transmitter amplifier is
referenced to the process. This creates the lowest noise environment for the
transmitter to make a stable reading. Use Table 3-1 to determine which
grounding option to follow for proper installation.
NOTE
Consult factory for installations requiring cathodic protection or situations
where there are high currents or high potential in the process.
The sensor 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 most effective grounding method is direct
connection from the sensor to earth ground with minimal impedance.
The Internal Ground Connection (Protective Ground Connection), located
inside the junction box, is the Internal Ground Connection screw. This screw
is identified by the ground symbol:
