Introduction
1.1 About concentration measurement
When measuring process fluids, the MFC 300 and MFC 400 converters allow the direct
measurement of: mass flow; total mass flow; density and temperature. From the mass flow and
density measurements, it is also possible to calculate values for volume flow and volume total. If
the process fluid is a mixture of two components, the individual data of those components,
together with the measured density, can be used to calculate the relative proportions. Where the
two components have the same, or similar, individual densities the mixture will also have the
same density, regardless of the relative proportions of the components. In such situations,
concentration calculations will not be possible. As the difference between the component
densities increases, it becomes easier to accurately measure the relative proportions of the
components.
