Modify matrix names and labels using ProLink III
For convenience, you can change the name of a concentration matrix and the label used for its measurement
unit. This does not affect measurement.
Procedure
1. Choose
Device Tools
>
Configuration
>
Process Measurement
>
Concentration Measurement
.
The
Concentration Measurement
window is displayed. It is organized into steps that allow you to
perform several different setup and configuration tasks. For this task, you will not use all the steps.
2. Scroll to Step 2, set
Matrix Being Configured
to the matrix you want to modify, and click
Change
Matrix
.
3. Scroll to Step 3, then perform the following actions:
a) Set
Concentration Units Label
to the label that will be used for the concentration unit.
b) If you set
Concentration Units Label
to Special, enter the custom label in
User-Defined Label
.
c) In
Matrix Name
, enter the name to be used for the matrix.
4. Click the
Apply
button at the bottom of Step 3.
Modify extrapolation alerts for CM using ProLink III
You can enable and disable extrapolation alerts, and set extrapolation alert limits. These parameters control
the behavior of the concentration measurement application but do not affect measurement directly.
Each concentration matrix is built for a specific density range and a specific temperature range. If line density
or line temperature goes outside the range, the transmitter will extrapolate concentration values. However,
extrapolation may affect accuracy. Extrapolation alerts are used to notify the operator that extrapolation is
occurring.
Each concentration matrix has its own extrapolation alert limits.

3. Scroll to Step 4.
4. Set
Extrapolation Alert Limit
to the point, in percent, at which an extrapolation alert will be posted.
5. Enable or disable the high and low limit alerts for temperature and density, as desired, and click
Apply
.
Extrapolation alerts in action
If
Extrapolation Limit
is set to 5%,
High Limit (Temp)
is enabled, and the active matrix is built for a
temperature range of 40 °F (4.4 °C) to 80 °F (26.7 °C), a high-temperature extrapolation alert will be posted if
line temperature goes above 82 °F (27.8 °C).
