Scaling of sulfuric acid in mass flow meters
Thread Content
30%~40% sulfuric acid an, possibly mixed with a small amount of ammonium bisulfate. If scaling occurs inside the mass flow meter, are there any simple and easy cleaning methods or “maintenance-free” solutions?
Proper insulation should be applied to the pipelines and flow meters; when selecting them prior to purchase, it is advisable to choose flow meter casings with insulated jackets. In the event of crystal deposits, hot water or low-pressure steam can be introduced, along with an increased flow rate. Additionally, a secondary line for cleaning is installed on the measurement pipeline to clean the flow meter with water when it is not in use.
As mentioned on the 3rd floor, ammonium sulfate dissolves very well; by setting up a bypass switch and using water for rinsing, the substances that are easily soluble can be removed. However, if it has accumulated in large quantities, it will become difficult to dissolve. Milk that sticks to the bottom cannot be washed away just by adding water
