ProLink III Device Tools > Configuration > Process Measurement > Line Density > Density Cutoff Low
Field Communicator Configure > Manual Setup > Measurements > Density > Density Cutoff
Overview
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 Low to the value you want to use.
The default value is 0.2 g/cm³. The range is 0.0 g/cm³ to 0.5 g/cm³.
4.2.4 Configure two-phase flow parameters
Display Not available
ProLink III Device Tools > Configuration > Process Measurement > Line Density
Field Communicator Configure > Manual Setup > Measurements > Density
Overview
The two-phase flow parameters control how the transmitter detects and reports two-
phase flow (gas in a liquid process or liquid in a gas process).
Note
Two-phase flow is sometimes referred to as slug flow.
Procedure
1. Set Two-Phase Flow Low Limit to the lowest density value that is considered normal in
your process.
Values below this will cause the transmitter to post Alert A105 (Two-Phase Flow).
Tip
Gas entrainment can cause your process density to drop temporarily. To reduce the
occurrence of two-phase flow alerts that are not significant to your process, set Two-Phase Flow
Low Limit slightly below your expected lowest process density.
