Base Time Unit
Base Time Unit provides the time unit from which to calculate the special
units. For example, if your special units is a volume per minute, select
minutes. Choose from the following units:
• Seconds (s)
• Minutes (min)
• Hours (h)
• Days (d)
User Defined Unit
User Defined Unit is a format variable that provides a record of the flow units
to which you are converting. The LCD on the Rosemount 8800D will display
the actual units you define. The Field Communicator will simply display
“SPCL.” There are four characters available to store the new units
designation.
Conversion Number
Conversion Number is used to relate base units to special units. For a
straight conversion of volume units from one to another, the conversion
number is the number of base units in the new unit.
For example, if you are converting from gallons to barrels and there are 31
gallons in a barrel, the conversion factor is 31. The conversion equation is as
follows (where barrels is the new volume unit):
1 gallon = 0.032258 bbl.
