Effect of flow direction on Frequency Outputs
Flow direction affects how the transmitter reports flow values via the Frequency Outputs.
The Frequency Outputs are affected by flow direction only if Frequency Output Process
Variable is set to a flow variable.

Effect of flow direction on Discrete Outputs
The flow direction parameter affects the Discrete Output behavior only if Discrete Output
Source is set to Flow Direction.

Effect of flow direction on digital communications
Flow direction affects how flow values are reported via digital communications. The
following table describes the effect of the flow direction parameter and actual flow
direction on flow values reported via digital communications.
