•
In general, lower damping values are preferable because there is less chance of data loss, and less
lag time between the actual measurement and the reported value.
•
For gas applications, Micro Motion recommends setting
Flow Damping
to 2.56 or higher.
The value you enter is automatically rounded down to the nearest valid value. Valid
damping values are shown in the following table.

Effect of Flow Damping on volume measurement
Flow Damping
affects volume measurement for liquid volume data.
Flow Damping
also affects
volume measurement for gas standard volume data. The transmitter calculates volume
data from the damped mass flow data.
Interaction between Flow Damping and Added Damping
In some circumstances, both
Flow Damping
and
Added Damping
are applied to the reported
mass flow value.
Flow Damping
controls the rate of change in flow process variables.
Added Damping
controls
the rate of change reported via the mA output. If
mA Output Process Variable
is set to
Mass
Flow Rate
, and both
Flow Damping
and
Added Damping
are set to non-zero values, flow
damping is applied first, and the added damping calculation is applied to the result of the
first calculation.

Mass Flow Cutoff
Overview
Mass Flow Cutoff
specifies the lowest mass flow rate that will be reported as measured. All
mass flow rates below this cutoff will be reported as 0.
