7.8 Set up concentration measurement using ProLink III
This section guides you through the tasks required to set up, configure, and implement concentration
measurement.
7.8.1 Enable the concentration measurement application using
ProLink III
The concentration measurement application must be enabled before you can perform any setup. If the
concentration measurement application was enabled at the factory, you do not need to enable it now.
Procedure
1. Choose Device Tools → Configuration → Transmitter Options.
2. Set Concentration Measurement to Enabled and click Apply.
7.8.2 Configure a concentration measurement matrix using
ProLink III
A concentration measurement matrix defines the relationship between density and concentration for your
process gas. You can configure up to six matrices.
Prerequisites
You must know the primary and secondary constituents of your process gas, and the density of each
constituent in pure form.
Procedure
1. Choose Device Tools → Configuration → Process Measurement → Concentration Measurement.
2. To use a gas variable, set Gas Purity Variable to Specific Gravity, Molecular Weight, or Relative Density.
Meter
Available option
Specific gravity Specific Gravity or Molecular Weight
Molecular weight Specific Gravity or Molecular Weight
Relative density Relative Density
3. Set Matrix Being Configured to the matrix you want to configure and click Change Matrix.
4. Set Concentration Units Label to the label to use for the measurement unit.
This selection does not affect measurement. It only selects a label.
5. If you set Concentration Units to Special, enter a string for the custom label.
6. Enter a name for the matrix.
7. Enter the density of the primary constituent of your process gas, in its pure form.
8. Enter the density of the secondary constituent of your process gas, in its pure form.
9. Click Apply.
