The calculation of the remaining capacity depends on the following factors:
• Flow rate
• Volume of the exchanger
• Salinity of the water at the exchanger inlet
• Total volume capacity of the resin
• Degree of efficiency of the exchanger

Before you start monitoring, specify the
remaining capacity of the exchanger resin.
This value makes allowances for the re-use of
resin that has already been used.
If a value is not entered manually, 100 % is
taken as the initial value for calculating the
current remaining capacity.
