Modify matrix names and labels using the
Field Communicator
For convenience, you can change the name of a concentration matrix and the label used
for its measurement unit. This does not affect measurement.
1. Choose Configure > Manual Setup > Measurements > Concentration Measurement > Configure
Matrix.
2. Set Matrix Being Configured to the matrix you want to modify.
3. Set Matrix Name to the name to be used for the matrix.
4. Set Concentration Unit to the label that will be used for the concentration unit.
5. If you set Concentration Unit to Special, choose Concentration Unit Label and enter the
custom label.
Modify concentration measurement operational parameters
using the Field Communicator
You can enable and disable extrapolation alerts, set extrapolation alert limits, and control
matrix switching. These parameters control the behavior of the concentration
measurement application but do not affect measurement directly. Additionally, for certain
types of concentration measurement, you can select the calculation type to be used.
1. Choose Configure > Manual Setup > Measurements > Concentration Measurement > Configure
Matrix.
2. Set Matrix Being Configured to the matrix you want to modify.
3. If applicable, set Equation Type to the type of calculation to be used.
Option Description
Specific
Gravity
Referred density is calculated from the matrix. The result is used in the specific
gravity equation. The output is specific gravity.
Baume Specific gravity is calculated as described above, and the result is used in the
°Baumé equation. The output is specific gravity and °Baumé (light or heavy).
Brix Specific gravity is calculated as described above and the result is used in the
°Brix equation. The output is specific gravity and °Brix.
Plato Specific gravity is calculated as described above, and the result is used n the
°Plato equation. The output is specific gravity and °Plato.
Twaddell Specific gravity is calculated as described above, and the result is used in the
°Twaddell equation. The output is specific gravity and °Twaddell.
This option is available only when Derived Variable is set to Specific Gravity.
4. Set up extrapolation alerts.
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
