Overview
A special measurement unit is a user-defined unit of measure that allows you to report
process data, totalizer data, and inventory data in a unit that is not available in the
transmitter. A special measurement unit is calculated from an existing measurement unit
using a conversion factor.
Procedure
1.
Specify Base Volume Unit.
Base Volume Unit is the existing volume unit that the special unit will be based on.
2. Specify Base Time Unit.
Base Time Unit is the existing time unit that the special unit will be based on.
3. Calculate Volume Flow Conversion Factor as follows:
(1) Unit based on oil barrels (42 U.S. gallons).
(2)
Unit based on U.S. beer barrels (31 U.S. gallons).
