Softener Monitor

Softener monitoring by conductivity ratio gives a continuous indication of performance. Sodium is typically more conductive than the hardness minerals it displaces, yielding a higher conductivity at the outlet. A ratio approaching 1 indicates that hardness ions are breaking through and that regeneration is needed.

Steam Power Measurements

The three conductivity measurements in power plants relate to water chemistry parameters as follows:

Specific conductivity -- chemical treatment level

Cation conductivity -- total anion contaminants

Degassed conductivity -- non-volatile anion contaminants

Cation minus degassed conductivities -- carbon dioxide
