Density parameters
Density parameters are listed and defined in Table 7-8. Density units are listed in Table 7-9.
Table 7-8 Density parameters
Variable Default Description
Density units g/cm
3
• Select the desired unit of density. See Table 7-9.
• Density outputs and displays will indicate density in the selected unit.
Density damping 1.6 sec • Damping filters out noise or the effects of rapid changes in density without
affecting measurement accuracy. See the section entitled Damping later in this
chapter. Range is 0.0–51.2 seconds.
• Milliamp outputs have an additional damping parameter. See Section 8.4.4.
Density cutoff 0.2 g/cm
3
• Enter the density value below which density outputs and displays will indicate zero
density. See the section entitled Cutoffs later in this chapter.
Slug low limit 0.000000
g/cm
3
• Enter the desired low limit, in g/cm
3
, for the process density. Range is
0.0–10.0 g/cm
3
.
• The entered value is the density below which a slug flow alarm will be generated.
• For more information about slug flow, see Slug flow alarms in Section 22.7.3.
Slug high limit 5.000000
g/cm
3
• Enter the desired high limit, in g/cm
3
, for the process density. Range is
0.0–10.0 g/cm
3
.
• The entered value is the density above which a slug flow alarm will be generated.
• For more information about slug flow, see Slug flow alarms in Section 22.7.3.
Slug duration 0.0 sec • Enter the number of seconds for which flow outputs will hold their last measured
flow rate while density is outside the range specified by the slug low limit and slug
high limit. Range is 0.0–60.0 seconds.
• If a value of 0.0 is entered, flow outputs will go to the level that indicates zero flow
as soon as slug flow is detected.
• For more information about slug duration, see Slug flow alarms in Section 22.7.3.
