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 depend on Lower Range Value configured for
the mA output:
• If Lower Range Value is set to 0, see Figure 1.
• If Lower Range Value is set to a negative value, see Figure 2.
