Electrolyzer fluid level

It is very important to keep the fluids in the electrolyzer at the fill level. 

The pressure tank must be situated so that the fluid level is also 34 to /211 from the top of the inside of the pressure tank. Be sure that the pressure tank and electrolyzer are situated correctly in relation to each other. 

To calibrate the sight glass, find and mark the fill point on the sight glass. It should be level with a point that is 34 to 1/2 below the bottom of the top flange in the electrolyzer, which should also be level with a point 34 to Vk below the inside of the top of the pressure tank. This is easy to do and is vitally necessary to the safe operation of this electrolyzer. 

As the water is used up in the system, the level will drop and the auto-matic sensor system will refill the pressure tank and electrolyzer, or you can f activate the refill manually. When the sensors are set up for this system, 

I place them closely so that the level never falls near or below the edge of the hydrogen duct. As you experiment with the system you will find the proper spacing and positions for the sensors, so that the system can operate safely.

For a gravity drain of the pressure tank and electrolyzer as mentioned above, the pump and 3-way valve must be located below the electrolyzer and pressure tank, so that the fluids will drain downward. The reservoir can positioned at any level, since the pump is used to drain it. 

Diaphragm Cell Level Control. There is no external feed of fluid to the catholyte in a diaphragm cell. Partly electrolyzed brine flows through the diaphragms instead, and the resultant catholyte, containing both NaCl and NaOH, is referred to as crude caustic or cell liquor. Hydrogen evolves from the cathodes located on the inside...
