Power Control Circuit Help

Might be simpler to jes get a pump a bit bigger than needed, run a recirculation loop back to the reservior, and leave it on.  Use a metering valve(s) on a leg(s) with level actuated soleniod to add extra water as needed.

Simpler still would be to set hydraulic gradient so as to always have the water circulating, and HHO coming off in the same pipe (see IronHead's latest pics in H V HHO).

But then, I may not be addressing your specific needs in that  rant.

The Upper sensor will just turn on a warning light indicating low water level in the cell. Its the lower sensor that will turn the pump on. But the pump will not turn off until it reaches the upper sensor. I'm trying to figure out the level that will keep the electrodes immersed with water.

@ Duke:

Am I missing something? Wouldn't the level be just slightly above the top of the plates?

Your drawing indicates the presence of a backflow preventor on the water supply line after the pump, at or near to the cell. This'll prevent hydrogen from flowing in the wrong direction and it'll also keep your line primed so there's water being supplied to the cell immediately. As soon as your sensor trips the pump, the level increases. No confusing math required!

Cheers, Mark.

yes, but I want to keep water much higher in the cell than just over the top of the electrodes. The one way valves keep the water going into the cell from underneath the electrodes to help with the extraction of hydroxy from the cell.

Water levels much higher than the cell stack itself requires much higher amperage to run  for the same HHO output as  keeping the water level  near the cell stack surface. Water level is critical . This holds true in  series, parallel and concentric cell types.
