Structure of the concentration matrix
The software supports two different concentration values:
•
Concentration in unit
(e. g.: % or°Bé)
The range of values is not limited, the value can be provided at the current output, the value can be selected in the Units
submenu.
•
Concentration in percent
(%)
The range of values is limited to 0 to 103.125 %. This value is only used for the internal calculation of the net mass flow. The net
mass flow can be output at the current and pulse outputs.
Concentration MIN / MAX limit:
−
5.0 to 105.0.
The matrix for calculating the concentration looks like this:
Temperature 1
…
Temperature n
Value 1 concentration in %
Value 1 concentration in unit
(e.g., % or°Bé)
Value 1, 1 density
…
Value n, 1 density
… …
…
…
…
Value m concentration in %
Value m concentration in unit
(e.g., % or°Bé)
Value 1, m density
…
Value n, m density
The following rules apply when entering values in the matrix:
• With one matrix: 2

The density values in a column must be in ascending order due to the algorithm used in the transmitter software.
Density x,1 < … < Density x,2 <…< Density x,M for 1

The temperature values must be in ascending order from left to right due to the algorithm used in the transmitter software.
Temperature 1 <…< Temperature x <…< Temperature N for 1

The concentration values must be monotonically ascending or monotonically descending from top to bottom due to the algorithm
used in the transmitter software.
