Table 8-2: Interaction between actual flow direction and Sensor Flow Direction Arrow
Actual flow direction Setting of Sensor Flow Direction
Arrow
Flow direction sent to outputs and
totalizers
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 Frequency Output Direction as desired.
Option Description
Positive Flow Only • Forward flow: The Frequency Output reports the flow rate according to the
configured scaling method.
• Reverse flow: The Frequency Output is 0 Hz.
Negative Flow
Only
• Forward flow: The Frequency Output is 0 Hz.
• Reverse flow: The Frequency Output reports the absolute value of the flow rate
according to the configured scaling method.
Both Positive and
Negative Flow
The Frequency Output reports the absolute value of the flow rate according to the
configured scaling method. It is not possible to distinguish between forward flow and
reverse flow from the Frequency Output alone. This setting is typically used in
combination with a discrete output configured to report flow direction.

Fault Action
Frequency Output Fault Action controls the behavior of the frequency output if the transmitter detects a
fault condition.
Important
• The fault action is implemented only if Alert Severity is set to Failure. If Alert Severity is set to any other
option, the fault action is not implemented.
• For some faults only: If Fault Timeout is set to a non-zero value, the transmitter will not implement the
fault action until the timeout has elapsed.
Procedure
1. Set Frequency Output Fault Action as desired.
