The insertion electromagnetic flowmeter is very popular with customers because of its high cost performance, convenient installation and maintenance, etc., so how to clean it in daily use? Today I bring you an introduction to the cleaning method of the insertion electromagnetic flowmeter.

 

1. 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.

2. Immerse in 4% hydrogen fluoride solution for 3~5s, take out and rinse with distilled water, then soak in 0.1mol/L hydrochloric acid solution for several hours, rinse with distilled water, and calibrate

3. For organic oil pollution and oil film pollution, the platinum or gold surface can be cleaned with detergent, then washed with pure water, and then immersed in 3.5MOL/L potassium chloride solution for 6 hours before use.

4. The surface of platinum is seriously polluted and an oxide film is formed. The platinum or gold surface can be polished with toothpaste, then washed with pure water, and then immersed in 3.5MOL/L potassium chloride solution for 6 hours before use.

 

Usually, it is necessary to perform periodic visual inspection of the electromagnetic flowmeter, check the surrounding environment of the electromagnetic flowmeter, remove dust, ensure that water and other substances do not enter, check whether the wiring is in good condition, and check whether there is a new strong electromagnetic field device near the instrument or a new wire crossing. meter. If the measuring medium is easy to contaminate the electrode or deposit or scale in the measuring tube wall, it should be cleaned and cleaned regularly.

 

The above is an introduction to the cleaning method of the plug-in electromagnetic flowmeter. I hope it can be helpful to everyone.
