Overview
Gas Standard Volume Flow Cutoff specifies the lowest gas standard volume flow rate that will
reported as measured. All gas standard volume flow rates below this cutoff will be
reported as 0.
Procedure
Set Gas Standard Volume Flow Cutoff to the value you want to use.
The default value for Gas Standard Volume Flow Cutoff is 0.0. The lower limit is 0.0. There is no
upper limit.
Interaction between Gas Standard Volume Flow Cutoff and
AO Cutoff
Gas Standard Volume Flow Cutoff defines the lowest Gas Standard Volume flow value that the
transmitter will report as measured. AO Cutoff defines the lowest flow rate that will be
reported via the mA output. If mA Output Process Variable is set to Gas Standard Volume Flow
Rate, the volume flow rate reported via the mA output is controlled by the higher of the
two cutoff values.
Gas Standard Volume Flow Cutoff affects both the gas standard volume flow values reported
via outputs and the gas standard volume flow values used in other transmitter behavior
(e.g., events defined on gas standard volume flow).
AO Cutoff affects only flow values reported via the mA output.
Example: Cutoff interaction with AO Cutoff lower than Gas Standard Volume Flow
Cutoff
Configuration:
Result: If the gas standard volume flow rate drops below 15 SLPM, the volume flow will be
reported as 0, and 0 will be used in all internal processing.
