How to clean the insertion electromagnetic flow meter correctly
The plug in electromagnetic flow meter
has the advantages of high cost performance, convenient installation and maintenance, etc. How to clean it in daily use?
For inorganic pollution, the electrode can be immersed in 0.1mol/L dilute hydrochloric acid for 30 minutes, washed with pure water, and then immersed in 3.5MOL/L potassium chloride solution for 6 hours before use.
