• The concentration measurement application must be enabled on your transmitter.
• The concentration matrix you want to use must be available on your transmitter, or
it must be available as a file on your computer.
• You must know the derived variable that your matrix is designed for.
• You must know the density unit used by your matrix.
• You must know the temperature unit used by your matrix.
• The concentration measurement application must be unlocked.
Procedure
1. Choose ProLink > Configuration > Density and set Density Units to the density unit used by
your matrix.
2. Choose ProLink > Configuration > Temperature and set Temp Units to the temperature unit
used by your matrix.
3. Choose

4. In Global Config, set
Derived Variable
to the derived variable that your matrix is
designed for.
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 Conc
(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.
5. Load one or more matrices.
a. In Curve Specific Config, set Curve Configured to the location to which the matrix
will be loaded.
b. Click
Load this curve from a file
, navigate to the matrix file on your PC, and load it.
c. Repeat until all required matrices are loaded.
6. 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. In Curve Specific Config, set
Curve Configured
to the matrix that you want to
configure.
b. Set
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.
