This parameter indicates the name of the instance, as assigned by default
(module mnemonic) or entered by the user.
Ref Temp.
Reference Temperature in °C.
Analog value in engineering units.
Ref Press.
Reference Pressure in the same units of the PIN analog input
Analog value, in engineering units with allowed range from -9999 to 99999.
Abs. Press.
Absolute atmospheric pressure, relative to vacuum. It is used to convert the PIN
and Ref. Press values to absolute values.
Analog value in engineering unit.
Compensation Mode
It allows to select the type of compensation you want to use.
No Compensation
The flow measure is returned on FOUT uncompensated, with the same vale at
QIN.
SEL = 0; OUT = QIN
Temperature
The flow is compensated only by the temperature measurement:
 TR + 273.14 

 TIN + 273.14 
SEL = 1; OUT = QIN * 
Pressure
The flow is compensated only by pressure measurement:
 PIN + PABS 

SEL = 2; OUT = QIN * 
 PR + PABS 
Both
The flow is fully compensated, in order to provide a true mass flow measure:
 TR + 273.14   PIN + PABS 
* 

SEL = 3; OUT = QIN * 
 TIN + 273.14   PR + PABS 
Output
FOUT
Corrected flow measure, calculated from the raw flow or differential pressure
measurement (QIN), according to the selected compensation formula.
Analog value in engineering units.
