NOTE
When configuring Standard or Normal Flow units to the volumetric flow, a
density ratio must be provided. See the Density/Density Ratio on page 3-9.
Special Units
Special Units allows you to create flow rate units that are not among the
standard options. They can be volumetric only. Configuration of a special unit
involves entry of these values: base volume unit, base time unit, user defined
unit and conversion number. Suppose you want the Rosemount 8800D to
display flow in barrels per minute instead of gallons per minute, and one
barrel is equal to 31.0 gallons.
• Base volume unit: gal
• Base time unit: min
• User defined unit: br
• Conversion number:
1
/31.0
See the specific variables listed below for more information on setting
special units.
Base Volume Unit
Base Volume Unit is the unit from which the conversion is made. You must
select one of the Field Communicator defined unit options:
• Gallons (gal)
• Liters (L)
• Imperial gallons (Impgal)
• Cubic meters (Cum)
• Barrels (bbl) where 1 bbl=42 gal
• Cubic Feet (Cuft)
