18. Add-on volume based dosing
The add-on volume based dosing offers a control version that is based on the volume and flow rate
of the water that is to be treated. Relay 1 is used to operate the dosing pump. With relay 2 you can
operate the circulation pump that provides water for the concentration measurement.
Note
It needs a flow meter that turns the flow rate into digital pulses, connected to
the digital input 2. (NPN, max 180 Hz)
If you have activated the add-on, the main menu shows the symbol DOSAGE.
In the menu DOSAGE you will find the following submenus:
DOSAGE, where you define all parameters necessary to calculate the
flow and the dosing volume.
DOSRELAY, where you define the output as pulse-pause or pulse-
frequency.
PUMP RELAY, where you define parameters for your circulation pump.
