10 Block SPECIAL FUNCTION Device Functions Proline Promass 83
REFERENCE
TEMPERATURE
(7009)
! Note!
This function is only available if OFF, °BRIX or FLEXIBLE was not selected in the
function DENSITY FUNCTION (7000).
Use this function to enter the reference temperature for the density functions and for
calculating the corrected volume flow and the corrected volume.
User input:
4-digit fixed-point number, including unit and sign
Factory setting:
20 °C
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 · U + A2 · U
2
+ A3 · U
3
+ A4 · U
4
+ B1 · T + B2 · T
2
+ B3 · T
3
K = Concentration
U= 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
OTHERS 3D
OTHERS 2D
Factory setting:
% MASS 3D
! Note!
If the relation between concentration density and temperature is given as table, the
equation coefficients can be determined by Endress+Hauser e.g. via a coefficient
calculation program and transmitted to the measuring device.
