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
The original mass flow rate value is divided by this value.
4.
Enter Mass Flow Conversion Factor.
5.
Set Mass Flow Label to the name you want to use for the mass flow unit.
6.
Set Mass Total Label to the name you want to use 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.
Example: Defining a special measurement unit for mass flow
You want to measure mass flow in ounces per second (oz/sec).
1.
Set Base Mass Unit to
Pounds
(lb).
2.
Set Base Time Unit to
Seconds
(sec).
3.
Calculate Mass Flow Conversion Factor:
a. 1 lb/sec = 16 oz/sec
b. Mass Flow Conversion Factor = 1 ÷ 16 = 0.0625
4.
Set Mass Flow Conversion Factor to
0.0625
.
5.
Set Mass Flow Label to
oz/sec
.
6.
Set Mass Total Label to
oz
.

Overview
Damping is used to smooth out small, rapid fluctuations in process measurement.
Damping Value specifies the time period (in seconds) over which the transmitter will
spread changes in the process variable. At the end of the interval, the internal value will
reflect 63% of the change in the actual measured value.
