Effect of Density Damping on volume measurement

Density Damping affects liquid volume measurement. Liquid volume values are calculated from the damped
density value rather than the measured density value. Density Damping does not affect gas standard volume
measurement.

Interaction between Density Damping and mA Output Damping

When the mA Output is configured to report density, both Density Damping and mA Output Damping are
applied to the reported density value.
Density Damping controls the rate of change in the value of the process variable in transmitter memory. mA
Output Damping controls the rate of change reported via the mA Output.
If mA Output Source is set to Density, and both Density Damping and mA Output Damping are set to non-
zero values, density damping is applied first, and the mA Output damping calculation is applied to the result
of the first calculation. This value is reported over the mA Output.

4.5.3 Configure Density Cutoff

Device Tools > Configuration > Process Measurement > Density > Density Cutoff

Configure > Manual Setup > Measurements > Density > Density Cutoff
Density Cutoff specifies the lowest density value that will be reported as measured. All density values below
this cutoff will be reported as 0.
Procedure
Set Density Cutoff to the value you want to use.
Default: 0.2 g/cm³
Range: 0.0 g/cm³ to 0.5 g/cm³
Effect of Density Cutoff on volume measurement
Density Cutoff affects liquid volume measurement. If the density value goes below Density Cutoff, the
volume flow rate is reported as 0. Density Cutoff does not affect gas standard volume measurement. Gas
standard volume values are always calculated from the value configured for Standard Gas Density or polled
value if configured for polled base density.

4.6 Configure temperature measurement

The temperature measurement parameters control how temperature data is processed. Temperature data is
used in several different ways, including temperature compensation, API referral, and concentration
measurement.
