1.3 Installation checklist
□Safety messages are provided throughout this content to protect personnel and
equipment. Read each safety message carefully before proceeding to the next step.
□If possible, install the meter in a location that will prevent direct exposure to sunlight.
The environmental limits for the meter may be further restricted by hazardous area
approvals.
□If you plan to mount the meter in a hazardous area:
—Verify that the meter has the appropriate hazardous area approval. Each meter has
a hazardous area approval tag attached to the meter housing.
—For ATEX/IECEx installations, strictly adhere to the safety instructions documented
in the ATEX/IECEx approvals documentation available on the Product
Documentation DVD shipped with the product or at www.emerson.com. Be sure to
reference this documentation in addition to the information shown in this guide.
□Verify that the local ambient and process temperatures are within the limits of the
meter.
□Follow the wiring instructions in the Model 5700 installation manual for signal and
power wiring.
□Mount the meter in a location and orientation that allows sufficient clearance to open
the housing cover. Allow 8 in (203 mm) to 10 in (254 mm) clearance at the wiring
access points.
□Install the meter so that the flow direction arrow on the sensor case matches the actual
forward flow of the process. Flow direction is also software-selectable.
1.3.1 Orientation options
You can mount the meter in any orientation as long as the conduit openings or display do
not point upward. Keep the sensor tubes full of process fluid to achieve best performance.
CAUTION
Installing the meter with the conduit openings or display facing upward risks moisture
entering the housing, which could damage the meter.

1.4 Best practices
•There are no pipe run requirements for Emerson meters. Straight runs of pipe
upstream or downstream are unnecessary.
•If the meter is installed in a vertical pipeline, liquids and slurries should flow upward
through the meters. Gases should flow downward.
•Keep the meter tubes full of process fluid.
•For halting flow through the meter with a single valve, install the valve downstream
from the meter.
•Minimize bending and torsional stress on the meter. Do not use the meter to align
misaligned piping.
•The meter does not require external supports. The flanges will support the sensor in
any orientation.
•Do not use the junction box to pick up the meter.
•Do not use the junction box as a step.
•Do not unscrew and rotate the junction box as this will break the wires.
•Do not install the meter in suspended pipes.
•Do not adjust the meter position by pulling or grasping the meter.
1.5 Temperature limits
Temperature type Min Max
Process temperature -40 °F (-40.0 °C) 356 °F (180.0 °C)
Ambient temperature -40 °F (-40.0 °C) 176 °F (80.0 °C)
Use the extended mount junction box (electronic interface code H) for process
temperatures above 176 °F (80.0 °C).
