Tip
In most cases, the concentration matrix that you ordered was loaded at the factory. If it was not, you have
several options for loading a matrix. You can also build a matrix.
• Temperature Source must be configured and set up.
• One matrix must be selected as the active matrix (the matrix used for measurement).
Requirements for matrices
A matrix is the set of coefficients used to convert process data to concentration, plus related parameters. The
matrix can be saved as a file.
The transmitter requires all matrices to be in .matrix format. You can use ProLink III to load matrices in other
formats:
• .xml (used by ProLink III)
The transmitter can store matrices in one of the six slots in memory.
Any matrix in a slot is available for use. In other words, it can be selected as the active matrix and used for
measurement. Matrices must be loaded into a slot before they can be used for measurement.
All matrices in slots must use the same derived variable.
Requirements for derived variables
A derived variable is the process variable that a concentration matrix measures. All other process variables are
calculated from the derived variable. There are eight possible derived variables. Each matrix is designed for
one specific derived variable.
The transmitter can store up to six matrices in six slots. All matrices in the six slots must use the same derived
variable. If you change the setting of Derived Variable, all matrices are deleted from the six slots.
Tip
Always ensure that Derived Variable is set correctly before loading matrices into slots.
Derived variables and net flow rate
If you want the transmitter to calculate Net Mass Flow Rate, the derived variable must be set to Mass
Concentration (Density). If your matrix is not designed for Mass Concentration (Density), contact customer
support for assistance.
If you want the transmitter to calculate Net Volume Flow Rate, the derived variable must be set to Volume
Concentration (Density). If your matrix is not designed for Volume Concentration (Density), contact customer
support for assistance.
Derived variables based on specific gravity
The following derived variables are based on specific gravity:
• Specific Gravity
• Concentration (Specific Gravity)
• Mass Concentration (Specific Gravity)
• Volume Concentration (Specific Gravity)
If you are using one of these derived variables, two additional parameters can be configured:
• Reference Temperature of Water (default setting: 4 °C)
• Water Density at Reference Temperature (default setting: 999.99988 kg/m³)
These two parameters are used to calculate specific gravity.
