Ozone Dose (Production mode: Dose Control)
The Ozone Dose is displayed as follows:
SP Setpoint in g/m³ process water
PV Actual value in g/m³ showing the calculated Process Value

Production Mode (Constant Setpoint)
In concentration or gas flow controlled systems, it must always be decided which parameter
should be the constant setpoint and which the variable parameter. The setpoint highlighted in
green is always the constant setpoint. The setpoint highlighted in gray is always the
calculated value (variable).

The ozone concentration is the constant setpoint:
Depending on the required ozone mass, the gas flow is
changed variably.
The gas flow is the constant setpoint:
Depending on the required ozone mass, the ozone
concentration is changed variably.
