3Pre-installation
Before installing the transmitter, there are several pre-installation steps that
should be completed to make the installation process easier:
• Identify options and configurations that apply to your application
• Set the hardware switches if necessary
• Consider mechanical, electrical, and environmental requirements
Note
Refer to the product reference manual for more detailed requirements.
Identify options and configurations
The typical transmitter installation 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
The transmitter may have up to four 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 is as follows:
Table 3-1: Hardware switch default settings
SettingFactory configuration
Alarm modeHigh
Internal/external analog powerInternal
Internal/external pulse powerExternal

5Wiring
5.1Conduit entries and connections
Transmitter conduit entries ports are ½"-14NPT as standard, M20 conduit
connections will use an adapter. Conduit connections should be made in
accordance with national, local, and plant electrical codes. Unused conduit
entries should be sealed with the appropriate certified plugs. The plastic
shipping plugs do not provide ingress protection.
5.2Conduit requirements
• For installations with an intrinsically safe electrode circuit, a separate
conduit for the coil cable and the electrode cable may be required.
• For installations with non-intrinsically safe electrode circuit, a single
dedicated conduit run for the coil drive and electrode cable between the
sensor and the remote transmitter may be acceptable. Removal of the
barriers for intrinsic safety isolation is permitted for non-intrinsically safe
electrode installations.
• Bundled cables from other equipment in a single conduit are likely to
create interference and noise in the system. See Figure 5-1.
• Electrode cables should not be run together in the same cable tray with
power cables.
• Output cables should not be run together with power cables.
• Select conduit size appropriate to feed cables through to the flowmeter.

Cable preparation
Prepare the ends of the coil drive and electrode cables as shown in Figure
5-3. Remove only enough insulation so that the exposed conductor fits
completely under the terminal connection. Best practice is to limit the
unshielded length (D) of each conductor to less than one inch. Excessive
removal of insulation may result in an unwanted electrical short to the
transmitter housing or other terminal connections. Excessive unshielded

5.7Analog output
The analog output signal is a 4-20 mA current loop. Depending on the IS
output option, the loop can be powered internally or externally via a
hardware switch located on the front of the electronics stack. The switch is
set to internal power when shipped from the factory. Intrinsically safe analog
output requires a shielded twisted pair cable. For HART communication, a
minimum resistance of 250 ohms is required. It is recommended to use
individually shielded twisted pair cable. The minimum conductor size is
24 AWG (0.51 mm) diameter for cable runs less than 5,000 feet (1,500 m)
and 20 AWG (0.81 mm) diameter for longer distances.
Note
For more information about the analog output characteristics, refer to the
product reference manual.

6Basic Configuration
Once the flow meter is installed and power has been supplied, the
transmitter must be configured using the LOI, if equipped, or a configuration
tool, such as ProLink III Software, AMS Device Manager, or AMS Trex Device
Communicator. Configuration settings are saved in nonvolatile memory
within the transmitter. Descriptions of more advanced functions are
included in the product reference manual.
6.1Basic 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 can be up to 32 characters long.
Calibration number
The sensor calibration number is a 16-digit number generated at the factory
during flow calibration, is unique to each sensor, and is located on the sensor
tag.
Flow units (PV)
The flow units variable specifies the format in which the flow rate will be
displayed. Units should be selected to meet your particular metering
needs. .
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.
Upper range value (URV)
The 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 flow units parameter. The URV may be set between –39.3 ft/s to
39.3 ft/s (–12 m/s to 12m/s). There must be at least 1 ft/s (0.3 m/s) span
between the URV and LRV.
Lower range value (LRV)
The 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 flow units parameter. The LRV may be set between –39.3 ft/s to 39.3 ft/s
(–12 m/s to 12m/s). There must be at least 1 ft/s (0.3 m/s) span between the
URV and LRV.
26 Rosemount™ 8782 Slurry Magnetic Flow Meter Transmitter
Page 27
November 2019Quick Start Guide
Auto zero
The Auto zero is recommended for optimum performance when a flow
meter is initially installed, and it typically does not need to be performed
again. However, if process conditions drastically change, a new Auto zero is
recommended. The sensor must be filled completely with process fluid at
zero flow. For more information, refer to the product reference manual.
6.2Local operator interface (LOI)
To access the transmitter menu, press the XMTR MENU key. Use the UP,
DOWN, LEFT(E), and RIGHT arrows to navigate the menu structure.
The display can be locked to prevent unintentional configuration changes.
The display lock can be activated through a HART communication device, or
by holding the UP arrow for three seconds and then following the on-screen
instructions.
