Specify Base Volume Unit.
Base Volume Unit is the existing volume unit that the special unit will be based on.
Specify Base Time Unit.
Base Time Unit is the existing time unit that the special unit will be based on.
Calculate Volume Flow Conversion Factor as follows:
a. x base units = y special units
b. Volume Flow Conversion Factor = x ÷ y
Enter Volume Flow Conversion Factor.
The original volume flow rate value is divided by this conversion factor.
Set Volume Flow Label to the name you want to use for the volume flow unit.
Set Volume Total Label to the name you want to use for the volume total and
volume inventory unit.
Set Base Volume Unit to Gallons (gal).
Set Base Time Unit to Seconds (sec).
