Example: Cutoff interaction with mA Output Cutoff lower than Mass Flow Cutoff
Configuration:
• mA Output Process Variable: Mass Flow Rate
• Frequency Output Process Variable: Mass Flow Rate
• mA Output Cutoff: 10g/sec
• Mass Flow Cutoff: 15g/sec
Result: If the mass flow rate drops below 15g/sec, mass flow will be reported as 0, and 0 will be used in all
internal processing.
Example: Cutoff interaction with mA Output Cutoff higher than Mass Flow Cutoff
Configuration:
• mA Output Process Variable: Mass Flow Rate
• Frequency Output Process Variable: Mass Flow Rate
• mA Output Cutoff: 15g/sec
• Mass Flow Cutoff: 10g/sec
Result:
• If the mass flow rate drops below 15g/sec but not below 10g/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 mass flow rate drops below 10g/sec, both outputs will report zero flow, and 0 will be used in all
internal processing.
4.3 Configure volume flow measurement for liquid
applications
The volume flow measurement parameters control how liquid volume flow is measured and reported. The
volume total and volume inventory are derived from volume flow data.
Restriction
You cannot implement both liquid volume flow and gas standard volume flow at the same time. Choose one or
the other.
