9. DOSING METHOD
The control of the pumps in the pH scale
is carried out through the PWM function.
The proportional band is set to values pH= 0.8

pH proportional dosing
The instrument allows the chemical measurement to be controlled and modified through
the pH Set Point automatically; adjusting the dosing though the pH motor controlled in
Proportional Time.
The dosing below is obtained by setting the following parameters:
Set point pH = 7.20 pH
Type of Dosing = Alkaline
Proportional Band = 0.80 pH
Set Point pH
Prop. Band
Motore pH
