! Note!
Function is not available unless % MASS / % VOLUME or % BLACK-LIQUOR was
selected in the DENSITY FUNCTION function (7000).
For entering the fluid-specific expansion coefficient for the carrier fluid for
nonlinear temperature curves. This value is required for temperature-
compensated calculation of the target fluid content in a two-phase fluid.
User input: 5-digit floating-point number, including unit and sign

! Note!
Function is not available unless % MASS / % VOLUME or % BLACK-LIQUOR was
selected in the DENSITY FUNCTION function (7000).
Use this function to enter the reference density (density at reference temp.) of the
target fluid. This value is required for temperature-compensated calculation of the
target fluid content in a two-phase fluid.
User input: 5-digit floating-point number, including units
Factory setting: 1.0000 kg/l
! Note!
• Carrier fluid = transporting liquid, (e.g. water)
Target fluid = material transported (e.g. lime powder)
• The appropriate unit is taken from the function UNIT REFERENCE DENSITY
(0421) (see Page 18).
