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.
Note
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 using the special
measurement unit.
Procedure
1.
Specify
Base Gas Standard Volume Unit
.
Base Gas Standard Volume Unit
is the existing gas standard 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
Gas Standard Volume Flow Conversion Factor
as follows:
a. x base units = y special units
b.
Gas Standard Volume Flow Conversion Factor
= x/y
4.
Enter the
Gas Standard Volume Flow Conversion Factor
.
5.
Set
Gas Standard Volume Flow Label
to the name you want to use for the gas standard
volume flow unit.
6.
Set
Gas Standard Volume Total Label
to the name you want to use for the gas standard
volume total and gas standard volume 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.
Example: Defining a special measurement unit for gas standard volume flow
You want to measure gas standard volume flow in thousands of standard cubic feet per
minute.
1.
Set
Base Gas Standard Volume Unit
to
SCFM
.
2.
Set
Base Time Unit
to
minutes
(min).
3.
Calculate the conversion factor:
a. 1 thousands of standard cubic feet per minute = 1000 cubic feet per minute
b.
Gas Standard Volume Flow Conversion Factor
= 1/1000 = 0.001
4.
Set
Gas Standard Volume Flow Conversion Factor
to
0.001
.
5.
Set
Gas Standard Volume Flow Label
to
KSCFM
.
6.
Set
Gas Standard Volume Total Label
to
KSCF
.
