Set up concentration measurement

This section guides you through loading and setting up a concentration matrix used for
measurement. It does not cover building a concentration matrix.
The concentration measurement application calculates concentration data from process
temperature and density. Micro Motion provides a set of concentration matrices that
provide the reference data for several standard industry applications and process fluids. If
desired, you can build a custom matrix for your process fluid, or purchase a custom matrix
from Micro Motion .
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

The concentration measurement application must be purchased 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.
