Emerson Micro Motion 1600 - 8.4.3 Configure mA Output Direction

Procedure
Set LRV and URV as desired.
Enter LRV and URV in the measurement units used for mA Output Source.
• Defaults: Specific to each process variable
• Range: Unlimited
Note
You can set URV below LRV. For example, you can set URV to 50 and LRV to 100. If you do this, an mA Output
will be inversely proportional to the value of mA Output Source.

mA Output Direction controls how conditions of forward flow and reverse flow affect the flow rates reported
by an mA Output.
Actual flow direction interacts with Sensor Flow Direction Arrow to determine the flow direction that the
transmitter uses in processing. See the following table.

Arrow
Flow direction sent to outputs and

Forward (same direction as Flow arrow
on sensor)
With Arrow Forward
Against Arrow Reverse
Reverse (opposite from Flow arrow on
sensor)
With Arrow Reverse
Against Arrow Forward
Procedure
Set mA Output Direction as desired.
Option
Description
Normal (default) Appropriate when your application needs to distinguish between forward flow and reverse
flow.
Absolute Value Appropriate when your application does not need to distinguish between forward flow and
reverse flow.
Important
mA Output Direction interacts with Lower Range Value (LRV). The effect of mA Output Direction on an mA
Output varies, depending on whether LRV < 0 or LRV ≥ 0.
