Planning
August 2019
•
There are no pipe run requirements for Micro Motion sensors. Straight runs of pipe
upstream or downstream are unnecessary.
•
If the sensor is installed in a vertical pipeline, liquids and slurries should flow upward
through the sensor.
•
Keep the sensor full of process fluid.
•
For halting flow through the sensor with a single valve, install the valve downstream
from the sensor.
•
Minimize bending and torsional piping loads on the meter. Do not use the meter to
align misaligned piping.
•
The sensor does not require external supports. The flanges will support the sensor in
any orientation.
1.3
Vibration limits
•
5 to 1,000 Hz; 1.25E-4 g2/Hz per IEC 60068-2-64
•
Total: 0.35g RMS
Vibration isolation should be used in installations above 0.35 g RMS or for applications
requiring Lloyd's approval.
Vibration isolation clamps are available as a spare part. For more information about
mounting a sensor in high vibration environments, contact Micro Motion.

Temperature limits
Component
Process fluid temperature
Ambient temperature
Notes
•
In all cases, the electronics cannot be operated where the ambient temperature is
below -40 °F (-40.0 °C) or above 140 °F (60.0 °C). If a sensor is to be used where the
ambient temperature is outside of the range permissible for the electronics, the
electronics must be remotely located where the ambient temperature is within the
permissible range, as indicated by the shaded area of the temperature limit graphs.
•
Temperature limits may be further restricted by hazardous area approvals. Refer to the
hazardous area approvals documentation shipped with the sensor or available from
www.emerson.com/flowmeasurement.
