Effect of Flow Direction on mA Outputs
Flow Direction affects how the transmitter reports flow values via the mA Outputs. The mA
Outputs are affected by Flow Direction only if mA Output Process Variable is set to a flow
variable.
Flow Direction and mA Outputs
The effect of Flow Direction on the mA Outputs depends on Lower Range Value configured
for the mA Output:

Relationship to Flow Direction arrow
on sensor
Appropriate when the Flow Direction ar-
row is in the same direction as the major-
ity of flow.
Appropriate when the Flow Direction ar-
row is in the opposite direction from the
majority of flow.
Flow Direction arrow is not relevant.
Appropriate when both forward and re-
verse flow are expected, and forward
flow will dominate, but the amount of re-
verse flow will be significant.
Appropriate when the Flow Direction ar-
row is in the opposite direction from the
majority of flow.
Appropriate when both forward and re-
verse flow are expected, and reverse flow
will dominate, but the amount of for-
ward flow will be significant.
