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:
Value 1 concentration in %
...
Value m concentration in %
The following rules apply when entering values in the matrix:
• With one matrix: 2 ≤ N ≤ 20; 2 ≤ M ≤ 20; N * M ≤ 100
• With two matrices: 2 ≤ N ≤ 20; 2 ≤ M ≤ 20; N * M ≤ 50
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 ≤ x ≤ M
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 ≤ x ≤ N
The concentration values must be monotonically ascending or monotonically descending from top to bottom due to the algorithm
used in the transmitter software.
Concentr. 1 <...< Concentr. x < ... < Concentr. N for 1 ≤ x ≤ N
or
Concentr. 1 >...> Concentr. x > ... > Concentr. N for 1 ≤ x ≤ N
