Device Functions Proline Promass 83 FOUNDATION Fieldbus 8 Block SPECIAL FUNCTION
Endress+Hauser 69
MODE
(7021)
! Note!
This function is not available unless the FLEXIBLE setting was selected in the
DENSITY FUNCTION function (7000).
Use this function to select a user-specific method of calculating the concentration of the
density and temperature measured.
In order to use this function, the following values are required:
• Concentration (see formula)
• Currently measured density
• Currently measured temperature
The concentration is calculated from the density and temperature as follows:
K = A0 + A1 · ρ + A2 · ρ
2
+ A3 · ρ
3
+ A4 · ρ
4
+ B1 · T + B2 · T
2
+ B3 · T
3
K = Concentration
ρ = Currently measured density
A0 = Value from function COEFFICIENT A0 (7032)
A1 = Value from function COEFFICIENT A1 (7033)
A2 = Value from function COEFFICIENT A2 (7034)
A3 = Value from function COEFFICIENT A3 (7035)
A4 = Value from function COEFFICIENT A4 (7036)
B1 = Value from function COEFFICIENT B1 (7037)
B2 = Value from function COEFFICIENT B2 (7038)
B3 = Value from function COEFFICIENT B3 (7039)
T = Currently measured temperature in °C
Options:
% MASS 3D
% VOLUME 3D
% MASS 2D
% VOLUME 2D
Factory setting:
% MASS 3D
! Note!
The relationship between the individual values (concentration, density and temperature)
can also be determined via the ToF Tool-Fieldtool Package operating program and be
transmitted to the measuring device.
