Density Compensation
- Density compensation can be selected to be actual flow or corrected to standard
conditions. Default factory setting is for actual conditions. The Vari-Green also allows for inputting the site elevation,
which will add density compensation for average atmospheric pressure based upon elevation above sea level.
Select System of Units
- US or SI units can be selected. US units will display in CFM and degrees Fahrenheit. SI
units will display in L/S and degrees Celsius.
NOTE: When changing between US and SI units, the flow configuration information will need to be converted
and updated. This is not done by the transmitter. The user must convert and input.
