The calculation of the dosage is made by establishing two setpoints and the relative
volume of dosage that is required in each of these points.
When the pH value is below the lower setpoint, the pump will not dose acid.
When pH is between both points, the chlorinator will send a proportional sig-
nal defined by both points. For example, in the case of the figure, if pH is at
8, the pump will dose al 50%.
When the pH is above the higher setpoint, the pump will dose to the fixed
volume defined for the higher point. In the case of the figure, 90%.
