Selection of level gauge for 35% hydrogen peroxide sodium hydroxide solution tank
Thread Content
For the level gauge of the 35% hydrogen-sodium hydroxide solution tank, a magnetic float level gauge (magnetic flap level gauge) should be used. Float material: 316L ； Material of the body and liquid-contacting parts: 304 ； Flange material: 304 ； How about this plan? Who has experience using it? What if the effect is?
My suggestion is to choose the casing based on the material of the equipment, while using titanium for the float – titanium provides excellent corrosion resistance against alkaline solutions. The price difference between titanium floats and those made of 18-8 stainless steel is not significant.
We mostly use old-fashioned glass panels.
For diaphragm caustic, using ordinary steel for storage tanks is fine for up to 15 years; the wall thickness of the level gauge tubes should be slightly thinner. Using 304 material is absolutely no problem
For the level gauge of the 35% hydrogen peroxide-sodium hydroxide solution tank, it is also necessary to consider temperature parameters as well as impurities; the higher the temperature, the faster the corrosion occurs, and chlorine also accelerates corrosion.

What do people usually choose for the heat tracing of magnetic float level gauges? I plan to use hot water; the temperature won’t be too high. Electric heating is a bit troublesome.
The float is made of titanium, which provides excellent corrosion resistance; it should not be exposed to high temperatures
It’s simpler and more practical to use pulley-mounted float balls; it requires less investment and no heating is needed
Top-mounted radar, ultrasound, and radio frequency admittance can all be used
A magnetic float level gauge will work; one with a PTFE lining is suitable.
There are already documents prohibiting glass panels
