A special measurement unit allows you to report process data, totalizer data, and inventory data in a
unit that is not hard-coded in the transmitter. A special measurement unit is calculated from an existing
measurement unit using a conversion factor.
Restriction
Although you cannot define a special measurement unit using the display, you can use the display to
select an existing special measurement unit and to view process data.
Procedure
1. Specify Base Mass Unit.
Base Mass Unit is the existing mass 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 Mass Flow Conversion Factor as follows:
a. x base units = y special units
b. Mass Flow Conversion Factor = x/y
4. Enter Mass Flow Conversion Factor.
5. Set Mass Flow Label to the label to be used for the mass flow unit.
6. Set Mass Total Label to the label to be used for the mass total and mass inventory unit.
The special measurement unit is stored in the transmitter. You can configure the transmitter to use the
special measurement unit at any time.
