Configure Density Damping - Emerson Micro Motion 2700 Configuration And Use Manual

If Two-Phase Flow Timeout is set to 0.0 seconds, the outputs that represent flow rate will
report a flow rate of 0 as soon as two-phase flow is detected.

Overview
Density Damping controls the amount of damping that will be applied to the line density
value.
Damping is used to smooth out small, rapid fluctuations in process measurement.
Damping Value specifies the time period (in seconds) over which the transmitter will
spread changes in the process variable. At the end of the interval, the internal value will
reflect 63% of the change in the actual measured value.
Tip
Density damping affects all process variables that are calculated from line density.
Procedure
Set Density Damping to the value you want to use.
The default value is 1.6 seconds. The range depends on the core processor type and the
setting of Update Rate, as shown in the following table:
Update Rate setting

Tips
• A high damping value makes the process variable appear smoother because the reported value
changes slowly.
• A low damping value makes the process variable appear more erratic because the reported value
changes more quickly.
• Whenever the damping value is non-zero, the reported measurement will lag the actual
measurement because the reported value is being averaged over time.
• 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.
