SPECIAL FUNCTION DENSITY FUNCTIONS CONFIGURATION<br />
REFERENCE<br />
TEMPERATURE<br />
(7009)<br />
! Note!<br />
This function is only available if OFF, °BRIX or FLEXIBLE was not selected in the<br />
function DENSITY FUNCTION (7000).<br />
Use this function to enter the reference temperature for the density functions and for<br />
calculating the corrected volume flow and the corrected volume.<br />
User input:<br />
4-digit fixed-point number, including unit and sign<br />
Factory setting:<br />
20 °C<br />
MODE<br />
(7021) ! Note!<br />
This function is not available unless the FLEXIBLE setting was selected in the DENSITY<br />
FUNCTION function (7000).<br />
Use this function to select a user-specific method <strong>of</strong> calculating the concentration <strong>of</strong> the<br />
density and temperature measured.<br />
In order to use this function, the following values are required:<br />
• Concentration (see formula)<br />
• Currently measured density<br />
• Currently measured temperature<br />
The concentration is calculated from the density and temperature as follows:<br />
K = A0 + A1 · + A2 · 2 + A3 · 3 + A4 · 4 + B1 · T + B2 · T 2 + B3 · T 3<br />
K = Concentration<br />
= currently measured density<br />
A0 = Value from function COEFFICIENT A0 (7032)<br />
A1 = Value from function COEFFICIENT A1 (7033)<br />
A2 = Value from function COEFFICIENT A2 (7034)<br />
A3 = Value from function COEFFICIENT A3 (7035)<br />
A4 = Value from function COEFFICIENT A4 (7036)<br />
B1 = Value from function COEFFICIENT B1 (7037)<br />
B2 = Value from function COEFFICIENT B2 (7038)<br />
B3 = Value from function COEFFICIENT B3 (7039)<br />
T = currently measured temperature in °C<br />
Options:<br />
% MASS 3D<br />
% VOLUME 3D<br />
% MASS 2D<br />
% VOLUME 2D<br />
OTHERS 3D<br />
OTHERS 2D<br />
Factory setting:<br />
% MASS 3D<br />
! Note!<br />
If the relation between concentration density and temperature is given as table, the<br />
equation coefficients can be determined by Endress+Hauser e.g. via a coefficient<br />
calculation program and transmitted to the measuring device.<br />
