Continuing fine tuning on HFE dry cell

Changed tubing to smaller liquid inlet and larger gas out let in an attempt to control direction of liquid flow, my check valve decided not to work, they wouldn’t open, I guess plastic air valves don’t like NAOH.
Anyway, the flow rate didn’t change stayed at 200ml/min, up’ d the Solution from 5tsp/L to 7 in [...]

PWM parts and diagram
