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:
a. x base units = y special units
b. Volume Flow Conversion Factor = x ÷ y
4.
Enter Volume Flow Conversion Factor.
The original volume flow rate value is divided by this conversion factor.
5.
Set Volume Flow Label to the name you want to use for the volume flow unit.
6.
Set Volume Total Label to the name you want to use for the volume total and
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 volume flow
You want to measure volume flow in pints per second (pints/sec).
1.
Set Base Volume Unit to
Gallons
(gal).
2.
Set Base Time Unit to
Seconds
(sec).
3.
Calculate the conversion factor:
a. 1 gal/sec = 8 pints/sec
b. Volume Flow Conversion Factor = 1 ÷ 8 = 0.1250
4.
Set Volume Flow Conversion Factor to
0.1250
.
5.
Set Volume Flow Label to
pints/sec
.
6.
Set Volume Total Label to
pints
.
