□
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.)
1.2 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.
1.3 Temperature limits
Sensors can be used in the process and ambient temperature ranges shown in the
temperature limit graphs. For the purposes of selecting electronics options, temperature
limit graphs should be used only as a general guide. If your process conditions are close to
the gray area, consult with your Micro Motion representative.
Note
• 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 areas 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 the
Micro Motion H-Series Hygienic Coriolis Flow and Density Meters Product Data Sheet . For
further quesitons, contact customer service.
