Special Units
Special Units allows you to create flow rate units that are not among
the standard options. They can be mass or volumetric units.
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 Model 8800C 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: 31.0
See the specific variables listed below for more information on setting
special units.
NOTE
The HART-based communicator will display the converted reading. The
actual unit specification does not appear.
Base Volume Unit
Base Volume Unit is the unit from which the conversion is made. You
must select one of the HART Communicator defined unit options:
• Gallons (gal)
• Liters (L)
• Imperial gallons (Impgal)
• Cubic meters (Cum)
• Barrels (bbl) where 1 standard bbl=42 gal
• Cubic Feet (cuft)
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)
