CORRECTED
VOLUME
CALCULATION
MODBUS register:
Data type:
Access:
6460
5129
Integer
read/write
This function is used to set the reference density for calculating the corrected
volume flow.
Options:
0 = CALCULATED REFERENCE DENSITY
1 = FIXED REFERENCE DENSITY
Factory setting: CALCULATED REFERENCE DENSITY
FIXED REFERENCE
DENSITY
MODBUS register:
Data type:
Access:
6461
5130
Float
read/write
! Note!
Function is not available unless the FIXED REFERENCE DENSITY setting was
selected in the CORRECTED VOLUME CALCULATION function (6460).
In this function, a fixed value for the reference density can be entered, with which
the corrected volume flow or corrected volume is calculated.
User input: 5-digit floating-point number
Factory setting: 1 kg/Nl
EXPANSION
COEFFICIENT
MODBUS register:
Data type:
Access:
6462
5132
Float
read/write
! Note!
Function is not available unless the CALCULATED REFERENCE DENSITY setting
was selected in the CORRECTED VOLUME CALCULATION function (6460).
For temperature-compensated calculations of the reference density an expansion
coefficient specific to the fluid is required and can be entered in this function (see
REFERENCE TEMPERATURE (6464) function on Page 114).
User input: 5-digit floating-point number
Factory setting: 0.5000 e-3 [1/K]
EXPANSION
COEFFICIENT
SQUARE
MODBUS register:
Data type:
Access:
6463
5134
Float
read/write
Use this function to enter a square expansion coefficient, if the temperature
compensation follows a nonlinear behavior (see REFERENCE TEMPERATURE
(6464) function on Page 114).
User input: 5-digit floating-point number
Factory setting: 0 e-6 [1/K
