Restriction
These tables are not appropriate for the following process fluids: propane and propane mixes,
butane and butane mixes, butadiene and butadiene mixes, isopentane, LNG, LPG, NGL, ethylene,
propylene, cyclohexane, aeromatics, asphalts, and road tars.
4.8 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
Before you can configure concentration measurement:
• 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.
