Step 2 Orientation
Flow direction
Micro Motion sensors measure accurately regardless of flow direction as
long as the sensor flow tubes remain filled with process fluid.
Flow direction arrow
The sensor has a flow direction arrow (see illustrations, pages 3-6) to
help you configure the transmitter for flow direction. Process fluid flowing
in the direction opposite to the flow direction arrow may cause
unexpected transmitter output unless the transmitter is configured
appropriately. For instructions on configuring the transmitter’s flow
direction parameter, refer to the transmitter instruction manual.
Vertical pipeline
If the sensor is installed in a vertical pipeline, liquids and slurries should
flow upward through the sensor. Gases may flow upward or downward.
Process fluid
Typical sensor orientations are shown in the tables on the following
pages:
• For measuring liquids, see page 14.
• For measuring gases, see page 15.
• For measuring slurries, see page 16.
Keys for sensor orientation
The sensor will function properly in any orientation if the sensor flow
tubes remain filled with process fluid.
