BASIC FUNCTION PROCESS PARAMETER REFERENCE PARAMETER<br />
CORRECTED VOLUME<br />
CALCULATION<br />
(6460)<br />
This function is used to set the reference density for calculating the corrected volume<br />
flow.<br />
Options:<br />
FIXED REFERENCE DENSITY<br />
CALCULATED REFERENCE DENSITY<br />
EXTERN (with this option, the reference density can be read in via the current input)<br />
Factory setting:<br />
CALCULATED REFERENCE DENSITY<br />
FIXED REF. DENSITY<br />
(6461) ! Note!<br />
This function is not available unless the FIXED REFERENCE DENSITY setting was<br />
selected in the CORRECTED VOLUME CALCULATION function (6460).<br />
In this function, a fixed value for the reference density can be entered, with which the<br />
corrected volume flow or corrected volume is calculated.<br />
User input:<br />
5-digit floating-point number<br />
Factory setting:<br />
1 kg/Nl<br />
EXPANSION<br />
COEFFICIENT<br />
(6462)<br />
! Note!<br />
This function is not available unless the CALCULATED REFERENCE DENSITY setting<br />
was selected in the CORRECTED VOLUME CALCULATION function (6460).<br />
For temperature-compensated calculations <strong>of</strong> the reference density an expansion<br />
coefficient specific to the fluid is required and can be entered in this function<br />
(see VALUE REFERENCE TEMPERATURE (6464) function on page 128).<br />
User input:<br />
5-digit floating-point number<br />
Factory setting:<br />
0.5000 e –3 [1/K]<br />
EXPANSION<br />
COEFFICIENT SQUARE<br />
(6463)<br />
Use this function to enter a square expansion coefficient, if the temperature<br />
compensation follows a nonlinear behavior (see VALUE REFERENCE TEMPERATURE<br />
(6464) function on page 128).<br />
User input:<br />
5-digit floating-point number<br />
Factory setting:<br />
0 e –6 [1/K 2 ]<br />
