Result: If the volume flow rate drops below 15 l/sec, volume flow will be reported as 0, and
0 will be used in all internal processing.
Example: Cutoff interaction with AO Cutoff higher than Volume Flow Cutoff
Configuration:
• mA Output Process Variable: Volume Flow Rate
• Frequency Output Process Variable: Volume Flow Rate
• AO Cutoff: 15 l/sec
• Volume Flow Cutoff: 10 l/sec
Result:
• If the volume flow rate drops below 15 l/sec but not below 10 l/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 10 l/sec, both outputs will report zero flow, and
0 will be used in all internal processing.
4.3 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.
The GSV flow measurement parameters include:
•
Volume Flow Type
•
Standard Gas Density
•
Gas Standard Volume Flow Measurement Unit
•
Gas Standard Volume Flow Cutoff
Restriction
You cannot implement both liquid volume flow and gas standard volume flow at the same time. You
must choose one or the other.
