The flowmeter... it's in the second picture, next to the aquaero. It's not a Swissflow . At least not any on the Swissflow page. I'll check the manufacturer tomorrow if i have time , i think there's one in the loop of one of the process simulators. But innovatek used them alot until recently.

Solenoids... as in mechanical actuators?
No, nothing that fancy. It just regulates the flow of the 12v pump to predefined levels for filling and bleeding. To avoid ar mixtures mainly in filling.
Althou it would be interesting to use such a system. I've worked with small actuators, but i had a Siemens PLC to poke around with , that made things painless. Well, almost. The scalable analog exits for one of the control loops were done more by ... well, instinct . Dont you just hate manuals and PDF's in german ... ?
