□
Orient the sensor so that personnel and equipment will not be exposed to escaping
pressurized discharge from the rupture disk. The sensor has a rupture disk to evacuate
the case in the unlikely event of a loss of primary containment.
□
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 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.

HPC010 vibration limits — vibration broadband
random
•
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 customer support.
