Configure process measurement
13.
Concentration process variables are now available on the transmitter. You can view and
report them in the same way that you view and report other process variables.

Configure concentration measurement using the
Field Communicator
This task guides you through setting up a concentration matrix to use for measurement. It
does not cover loading or building a concentration matrix.
Note
Concentration matrices can be made available on your transmitter either by loading an existing
matrix from a file or by building a new matrix. Up to six matrices can be available on your transmitter,
but only one can be used for measurement at any given time. See Micro Motion Enhanced Density
Application: Theory, Configuration, and Use for detailed information on building a matrix.
Prerequisites
Before you can configure concentration measurement:
Procedure
1.
2.
3.
4.
64
Set Active Matrix to the matrix to be used for measurement.
The concentration measurement application must be enabled on your transmitter.
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.
Choose Online > Configure > Manual Setup > Measurements > Density and set Density Unit to
match the density unit used by your matrix.

Configuration.
Set up extrapolation alerts.
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 alerts are used to notify the operator that
extrapolation is occurring.
a. Choose Online > Configure > Manual Setup > Measurements > Conc Measurement (CM) >
Matrix Configuration.
b. Set Matrix Being Configured to the matrix that you want to configure.
c. Set Extrapolation Alert Limit to the point, in percent, at which an extrapolation alert
will be posted.
