Example: Cutoff interaction with mAO Cutoff lower than Volume Flow Cutoff
Configuration:
• mA Output Process Variable: Volume Flow Rate
• Frequency Output Process Variable: Volume Flow Rate
• AO Cutoff: 10l/sec
• Volume Flow Cutoff: 15l/sec
Result: If the volume flow rate drops below 15l/sec, volume flow will be reported as 0, and 0 will be used in all
internal processing.
Example: Cutoff interaction with mAO Cutoff higher than Volume Flow Cutoff
Configuration:
• mA Output Process Variable: Volume Flow Rate
• Frequency Output Process Variable: Volume Flow Rate
• AO Cutoff: 15l/sec
• Volume Flow Cutoff: 10l/sec
Result:
• If the volume flow rate drops below 15l/sec but not below 10l/sec:
— The 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 volume flow rate drops below 10l/sec, both outputs will report zero flow, and 0 will be used in all
internal processing.
4.4 Configure Gas Standard Volume (GSV) flow
measurement
The gas standard volume (GSV) flow measurement parameters control how gas standard volume flow is
measured and reported.
Restriction
You cannot implement both liquid volume flow and gas standard volume flow at the same time. Choose one or
the other.
