□
The sensor has a pressure relief feature to evacuate the case in the unlikely event of
a loss of primary containment:
-
The pressure relief feature is located underneath the calibration tag.
-
Orient the sensor so that personnel and equipment will not be exposed to
escaping pressurized discharge along the pressure relief path.

CAUTION!
Failure to properly orient the sensor could result in exposure to pressurized
discharge. Orient the sensor in a way that will not expose personnel and equipment
to the pressure relief path.
-
If the pressure relief feature is activated by a loss of primary containment, the
calibration tag will release from the case.
□
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.)

Best practices
The following information can help you get the most from your sensor.
•
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. Gases should flow downward.
•
Keep the sensor tubes 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 stress 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.
