Building a "Bubbler"

A "Bubbler" is a simple column of water housed in a tube that the Hydroxy gas bubbles up through on its way to the engine or devise that your using the Hydroxy gas in...
...
its Construction is very straight Forward
a 2" pvc pipe 12" long (longer is better)
a 2" pvc Pipe cap glued on one end of the pipe
a 2" expandable Plug cap (red in picture) slid into the other end
now you have a closed pipe you need 2 outlets one on the bottom
and one on the top just below the expandable cap PLUG
drill and tap the holes to fit the brass hose barbs you purchase
to fit the Line you are using, usually 3/8 or 1/4 gas line is used.
a one way check valve found at some auto stores is used between the bubbler and the Hydroxy generator to stop the Hydroxy generator from sucking the water out of the Bubbler after shut down due to the contraction of the heat of the unit cooling down.
( make sure the one way check valve is pointed to the bubbler! so gas will go THROUGH the check valve into the bubbler but water cannot go back into the generator.)
...
IN most cases a 12"to 19" Bubbler will do the trick in the 2" diam.
but if Real large volumes of gas are being pushed through the bubbler
a larger size tube may be needed and an addition of more than one hose barb at the bottom and the hydroxy gas line should "T" into them this divides the gas into 2 or more columns and helps to prevent the ignition of the gas from traveling through the water if the flow is very great ( yes, it can do just that !)
so below 4LPM one bubbler should do of the size I described
above that in output I'd feel better about having a 4" pipe with 2 or 3 hose barbs on it and dividing the gas into 2 or 3 columns of bubbles rather than one.
......
the picture I drew with Gmax below has 2 brass Hose barbs on the bottom for gas input and one brass hose barb on the top for gas to the engines intake, the container is filled with normal water.
