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.
• Default: 0.0
• Range: 0.0 to any positive value
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 through
outputs and the gas standard volume flow values used in other transmitter behavior (for example, events
defined on gas standard volume flow).
mA Output Cutoff affects only flow values reported via the mA Output.
Cutoff interaction with mA Output Cutoff lower than Gas Standard Volume Flow Cutoff
Configuration:
• mA Output Process Variable for the primary mA Output: Gas Standard Volume Flow Rate
Frequency Output Process Variable: Gas Standard Volume Flow Rate
•
• mA Output Cutoff for the primary mA Output: 10 SLPM (standard liters per minute)
Gas Standard Volume Flow Cutoff: 15 SLPM
•
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.
Cutoff interaction with mA Output Cutoff higher than Gas Standard Volume Flow Cutoff
Configuration:
• mA Output Process Variable for the primary mA Output: Gas Standard Volume Flow Rate
Frequency Output Process Variable: Gas Standard Volume Flow Rate
•
• mA Output Cutoff for the primary mA Output: 15 SLPM (standard liters per minute)
Gas Standard Volume Flow Cutoff: 10 SLPM
