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

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.

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
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
If the gas standard volume flow rate drops below 15 SLPM but not below 10 SLPM:
-
The primary mA Output will report zero flow.
-
The Frequency Output will report the actual flow rate, and the actual flow rate
will be used in all internal processing.
If the gas standard volume flow rate drops below 10 SLPM, both outputs will report
zero flow, and 0 will be used in all internal processing.
