I have two PL-LY splitter.
The first splitter I connected to "Level 1&2" socket. And connect two flow sensor there. It works OK.
The second splitter I connected to "Level 3&4" socket. And connect level sensor ( it works OK ) and trying connect 3th flow sensor.

The GCC does not see 3th flow sensor. It can only 1 and 2 choose at the page 'Profilux - Flow-sensor'.
There are only 1 or 2 to choice on the 'connected at level sensor' column

How to connect 3th flow sensor to Profilux 3.1T ex?
