What type of level gauge is suitable for dilute alkali storage tanks?
Thread Content
Sea friends, may I ask what type of level gauge is suitable for storing dilute alkalis and concentrated alkalis? We are currently using a flap level gauge, but the problem is that the flaps no longer display any reading. The reason could be that alkali crystals have blocked the inlet, or it might be that impurities have gotten stuck in the float. So I would like to ask you all: those of you who have used dilute alkalis must have encountered such problems as well, and I wonder how you solved them.
Add heat tracing to the level gauge; alkaline solutions tend to crystallize at low temperatures.
Add heat tracing; there’s no other way~~
We are using radar level gauges, and there have been no problems at all
We also use flap level gauges; once crystallization occurs, it can only be cleaned.
We also use radar level gauges, and no problems have occurred so far
The simplest and most practical: differential pressure level gauge
If there’s no pressure, use a plexiglass level gauge directly
For the level and interface detection of the alkali washing tanks in these factories, single-flange and double-flange designs are used. However, during operation, crystallization and contamination on the flange surfaces do occur from time to time, and this issue can only be addressed through maintenance. Compared to magnetic level gauges, blockages occur much less frequently. A drain valve is installed at the bottom of the flange; when blockages or crystallizations arise, steam can be used to clear them, which is a better solution than disassembly and cleaning. Alkali solutions are not only painful to touch but also have a strong unpleasant odor, making it difficult to clean clothes that come into contact with them.
The float is directly immersed in the alkali tank, eliminating the need for a connecting guide tube
