Suspension measure
Yes/No
If you select yes the Solid density and liquid density parameters are taken into account in
the calculation (see also chapter 8.4).
Solid density
Enter Solid density (g/cm
3
) of component to be measured (only for suspension meas-
urements). See also chapter 8.4.
Liquid density
Enter liquid density (g/cm
3
) only for suspension measurements. This is the density of the
carrier liquid or, with liquid mixtures, the density of the attendant component.
Water TC ?
Yes/No
Only for measurements of suspensions using water as carrier liquid and temperature
compensation (via PT 100 or current input).
When temperature compensation for water is selected, the automatic temperature com-
pensation (TC1, TC2) is disabled and the temperature coefficient for water is used. Thus,
• the different temperature coefficient of water at different temperatures and
• the temperature influence which decreases with rising solids contents
are taken into account.
In this case, the next query is “Reference temperature” (see also chapter 7).
Temperature coefficient TC1
Enter linear temperature coefficient (999.999e
-99
to 999.999e
+99
). This coefficient usually
suffices for minor temperature changes of ± 20°C (see chapter 7).
Temperature coefficient TC2
Enter square temperature coefficient (999.999e
-99
to 999.999e
+99
). We recommend en-
tering TC2 in addition for minor temperature variations > 20°C (see chapter 7).
Reference temperature
Enter the reference temperature for the density, concentration or mass flow measure-
ment. If the actual temperature deviates from the reference temperature entered here,
the measured density or concentration values are temperature corrected (see chapter 7).
