Choose Device Tools > Configuration > Process Measurement > Concentration Measurement.
Set Derived Variable to the derived variable that your matrix is designed for, and click
Apply.
Important
• All concentration matrices on your transmitter must use the same derived variable. If you
are using one of the standard matrices from Micro Motion, set Derived Variable to Mass
Concentration (Density). If you are using a custom matrix, see the reference information for
your matrix.
• If you change the setting of Derived Variable, all existing concentration matrices will be
deleted from transmitter memory. Set Derived Variable before loading concentration
matrices.
Load one or more matrices.
a. Set Matrix Being Configured to the location to which the matrix will be loaded.
b. Click Load Matrix from a File, navigate to the matrix file on your computer, and load
it.
c. Repeat until all required matrices are loaded.
Review and configure matrix data.
a. If necessary, set Matrix Being Configured to the matrix you want to view, and click
Change Matrix.
b. Set Concentration Unit to the label that will be used for the concentration unit.
c. If you set Concentration Unit to Special, enter the custom label.
d. If desired, change the matrix name.
e. Review the data points for this matrix.
f. Do not change Reference Temperature or Curve Fit Maximum Order.
g. If you changed any matrix data, click Apply.
Set up extrapolation alarms.
Each concentration matrix is built for a specific density range and a specific
temperature range. If process density or process temperature goes outside the
range, the transmitter will extrapolate concentration values. However, extrapolation
may affect accuracy. Extrapolation alarms are used to notify the operator that
extrapolation is occurring.
a. If necessary, set Matrix Being Configured to the matrix you want to view, and click
Change Matrix.
b. Set Extrapolation Alarm Limit to the point, in percent, at which an extrapolation
alarm will be posted.
c. Enable or disable the high and low limit alarms for temperature and density, as
desired, and click Apply.
