Description:
INSTALLATION PROCEDURES
Rosemount 8732 installation includes both detailed mechanical and electrical
installation procedures.
Mount the Transmitter
Remote-mounted transmitters 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 8732 to the mounting bracket using the mounting screws.
Surface Mounting
To surface mount the transmitter:
1. Attach the 8732 to the mounting location using the mounting screws.
To convert from integral mount to remote mount transmitter, consult
Manual Supplement: Integral Mount to Remote Mount Conversion
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 when used with
Rosemount sensors.
Transmitter to Sensor Wiring
Flanged and wafer sensors have two conduit ports as shown in Figure 2-16.
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 from
multiple magnetic flowmeters 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 2-16 for the proper conduit installation diagram and
Table 2-3 for recommended cable. For integral and remote wiring diagrams
refer to Figure 2-19.

Notice :
Environmental Considerations
To ensure maximum transmitter life, avoid temperature extremes and vibration. Typical problem areas include:
• 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 a harsh environment and provide easy access for configuration or service.
Rosemount 8732 transmitters require external power so there must be access to a suitable power source.
