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
mA Output Cutoff
Gas Standard Volume Flow Cutoff defines the lowest Gas Standard Volume flow value that
the transmitter will report as measured. mA Output 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).
mA Output Cutoff affects only flow values reported via the mA Output.
Example: Cutoff interaction with mA Output Cutoff lower than Gas Standard Volume
Flow Cutoff
