Integrate the meter with the control system
t Example: Cutoff interaction
Configuration:
• mA Output Process Variable = Mass Flow Rate
• Frequency Output Process Variable = Mass Flow Rate
• AO Cutoff = 10 g/s
• Mass Flow Cutoff = 15 g/s
Result: If the mass flow rate drops below 15 g/s, all outputs representing mass flow will report zero flow.
t Example: Cutoff interaction
Configuration:
• mA Output Process Variable = Mass Flow Rate
• Frequency Output Process Variable = Mass Flow Rate
• AO Cutoff = 15 g/s
• Mass Flow Cutoff = 10 g/s
Result:
• If the mass flow rate drops below 15 g/s but not below 10 g/s:
− The mA output will report zero flow.
− The frequency output will report the actual flow rate.
• If the mass flow rate drops below 10 g/s, both outputs will report zero flow.
7.1.4 Configure Added Damping

ProLink II ProLink→Configuration→Analog Output→Primary/Secondary Output→AO Added Damp
Field Communicator Configure→Manual Setup→Inputs/Outputs→mA Output 1→mA Output Settings→PV Added Damping
Configure→Manual Setup→Inputs/Outputs→mA Output 2→mA Output Settings→PV Added Damping
Added Damping controls the amount of damping that will be applied to the mA output. It affects the
reporting of mA Output Process Variable through the mA output only. It does not affect the reporting of that
process variable via any other method (e.g., the frequency output or digital communications), or the
value of the process variable used in calculations.
Note
Added Damping is not applied if the mA output is fixed (for example, during loop testing) or if the mA output
is reporting a fault. Added Damping is applied while sensor simulation is active.
Procedure
Set Added Damping to the desired value.
The default value is 0.0 seconds.
