DENSITY
FUNCTION
MODBUS register:
Data type:
Access:
7000
2207
Integer
read/write
For selecting the density function which is used to calculate special density values
or the percentage proportion of components in two-phase fluids.
User input:
0 = OFF
1 = % MASS / % VOLUME
2 = % BLACK-LIQUOR
3 = °BAUME > 1 SG
4 = °BAUME < 1 SG
5 = ° API
6 = ° PLATO
7 = ° BALLING
8 = ° BRIX
9 = FLEXIBLE
Factory setting: OFF

Access:
7001
2208
Float
read/write
! 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
carrier 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).

2210
Float
read/write
! 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 linear
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
Factory setting: 0.5000 e-3 [1/K]
