Configuring Process Measurement
4.10.1
Damping and volume measurement
When configuring damping values, note the following:
•
Liquid volume flow is derived from mass and density measurements; therefore, any damping
applied to mass flow and density will affect liquid volume measurement.
applied to mass flow and density will affect liquid volume measurement.
•
Gas standard volume flow is derived from mass flow measurement, but not from density
measurement. Therefore, only damping applied to mass flow will affect gas standard volume
measurement.
measurement. Therefore, only damping applied to mass flow will affect gas standard volume
measurement.
Be sure to set damping values accordingly.

Interaction with the Added Damping parameter
The mA output has a damping parameter called Added Damping. If damping is set to non-zero value
for flow, density, or temperature, the same process variable is assigned to the mA output, and Added
Damping is also set to a non-zero value, the effect of damping the process variable is calculated first,
and the added damping calculation is applied to the result of that calculation.

See Section 6.2.4 for more information on the Added Damping parameter.
