When an analog input is used for the flow rate, this parameter
performs the following functions:
• Enables and disables flow meter functions. This parameter
must be set to a value greater than 0 to enable flow meter
functions.
• Sets the scaling for the "Flow Rate" analog input.
• Sets the scaling for the "Flow Rate" analog output.
• Sets the display scaling when "Flow Rate" is used as the PID
Flow Meter Scale feedback.
When an pulse input is used for the flow rate, this parameter
performs the following functions:
• Enables and disables flow meter functions. Parameter must
be set to a value greater than zero to enable flow meter
functions.
• Sets the scaling for the "Flow Rate" analog output.
• Sets the display scaling when "Flow Rate" is used as the PID
feedback.
Sets the scaling for the turbine in pulses per gallon.
Pulses/Gallon = P6-02 + P6-03
Turbine Scale 1
This parameter is internally lower-limited to 0.0001 ppG.
Turbine Scale 2
Sets the display units for monitor U1-83, P2-02, P6-06, P6-17,

All other settings have no effect.
Note:
Sets the level below which the flow must fall for longer than the
time set in P6-07 to trigger a Low Flow condition.
Low Flow Level
Setting this parameter to 0.0 will disable the function.
Sets the length of time that the flow rate must be below the level
set in P6-06 to detect a Low Flow condition.
Low Flow Tim Run
Sets the length of time that the drive will wait after coming out
of a zero speed condition before activating Low Flow detection.
Low Flow Time St

Determines drive response when a Low Flow condition is

Set the length of time that the drive will wait before attempting
LowFlow Restart an auto-restart of the Low Flow fault.
This parameter is effective only when P6-09 is set to 3.
Description
After this parameter is changed, the setting will
automatically return to "0".
This feature is canceled when the Flow Rate rises
above the Low Flow Level for the time set in
P6-21, Low Flow Start Delay Cancel Time.
