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 the 8712H reference manual for any restrictions
associated with a safe installation.

• 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.

In an Explosion-Proof/Flame-Proof installation, do not remove the
flowtube cover when power is applied to the unit.

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 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.

Rosemount 8712H

Before installing the Rosemount 8712H 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 8712H 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 8712H is mounted separately from the flowtube, it
is not subject to limitations that might apply to the flowtube.

Rosemount 8712H

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 8712H transmitters
require external power and there must be access to a suitable power
source.

Installation Procedures

Rosemount 8712H 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 8712H to the mounting plate using the mounting screws.

Surface Mounting

To surface mount the transmitter:

1. Attach the 8712H to the mounting location using the mounting
screws.

Rosemount 8712H

Identify Options and Configurations

The standard application of the 8712H 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

• PZR (Positive Zero Return)

• Ultrasonic Control

• 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 8712H 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:

Failure Alarm Mode: HIGH

Internal/External Analog Power: INTERNAL

Transmitter Security: OFF

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.

Electrical Considerations

Before making any electrical connections to the 8712H, consider the
following standards and be sure to have the proper power supply,
conduit, and other accessories.

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).

Figure 3. Upstream and Downstream Straight Pipe Diameters

Flow Direction

The flowtube should be mounted so that 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 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.

STEP 4: INSTALLATION (FLANGED FLOWTUBE)

00825-0100-4729, Rev BB
August 2015

Rosemount 8712H

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 o r 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 pressure.

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 11. 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.

Options, Considerations, and Procedures

Figure 14. Supply Current versus Input Voltage

Step 6.2 Transmitter Communication Input
Connect 4–20 mA Loop External Power Source

The 4–20 mA output loop signal may be powered internally or
externally. The default position of the internal/external analog power
jumper is in the internal position. The user-selectable power supply
jumper is located on the electronics board.

Internal

The 4–20 mA analog power loop may be powered from the transmitter
itself. Resistance in the loop must be 1,000 ohms or less. If a HART
Communicator or control system will be used, it must be connected
across a minimum of 250 ohms resistance in the loop.

External

HART multidrop installations require a 10–30 V dc external analog
power source. If a HART Communicator or control system is to be
used, it must be connected across a minimum of 250 ohms resistance
in the loop.

To connect external power to the 4–20 mA loop, connect -dc to
Terminal 8 and +dc to Terminal 7. (See Figure 12)

NOTE

To connect any of the other output options (pulse output for totalizing,
auxiliary output for switch closure, or positive zero return), consult the
the comprehensive product manual.

Step 6.3 Transmitter to Flowtube Wiring

A single dedicated conduit run for the coil drive and electrode cables is
needed between a flowtube 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.

Step 7: Basic Configuration

Once the magnetic flowmeter is installed and power has been
supplied, transmitter must be configured through the basic setup.
These parameters can be configured through either a local operator
interface, a HART Communicator or AMS. A table of all the
parameters are on page 25. Descriptions of the more advanced
functions are included in the comprehensive product manual.

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 Rate Units

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), or analog output range, is preset to 30
ft/s at the factory. The units that appear will be the same as those
selected under the units parameter.

LRV (Lower Range Value)

Reset the lower range value (LRV), or analog output zero, 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 –30 ft/s to 30 ft/s.

Line Size

The line size (tube size) must be set to match the actual flowtube
connected to the transmitter. The size must be specified in inches
according to the available sizes listed below.

Calibration Number

The tube calibration number is a 16-digit number used to identify
flowtubes calibrated at the Rosemount factory.
