The measurement principle of china slurry electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. The measurement of explosion-proof slurry electromagnetic flowmeter is composed of sensor and converter. The sensor is installed on the measurement pipeline. The converter can be combined and connected with the sensor, which is called integrated slurry electromagnetic flowmeter products. The converter is installed within 30 meters or 100 meters from the sensor, The two are connected by shielded cable, which is called separated electromagnetic flowmeter.

1. Measurement of stainless steel slurry electromagnetic flowmeter products: it is used for weakly corrosive media such as industrial water, domestic water and sewage. It is suitable for industrial departments such as petroleum, chemical industry and steel, as well as municipal, environmental protection and other fields.

2. Measurement of alloy B china slurry electromagnetic flowmeter products: it has good corrosion resistance to hydrochloric acid of all concentrations below the boiling point, and also resistant to the corrosion of sulfuric acid, phosphoric acid, hydrofluoric acid, organic acid and other non chlorinated acids, alkalis and non oxidizing salts.

3. Measurement of alloy C china slurry electromagnetic flowmeter products: it can resist the corrosion of non oxidizing acids, such as nitric acid, mixed acid, or mixed medium of chromic acid and sulfuric acid, as well as the corrosion of oxidizing salts, such as "Fe", Cu "or containing other oxidants, such as hypochlorite solution higher than normal temperature and seawater.

4. Titanium: it can resist the corrosion of seawater, various chlorides and hypochlorites, oxidizing acids (including fuming sulfuric acid), organic acids and alkalis. It is not resistant to the corrosion of relatively pure reducing acids (such as sulfuric acid and hydrochloric acid), but if the acid contains oxidants (such as nitric acid, FC + +, Cu + +), the corrosion will be greatly reduced.

5. Tantalum: it has excellent corrosion resistance, which is very similar to glass. Except hydrofluoric acid, fuming sulfuric acid and alkali, it can resist the corrosion of almost all chemical media (including hydrochloric acid, nitric acid with boiling point and sulfuric acid below L50 ℃). It is easy to resist corrosion in alkali.

6. Platinum / titanium alloy: it can withstand almost all chemical media, but it is not suitable for aqua regia and ammonium salt.

7. Stainless steel coated tungsten carbide: used for non corrosive and strong abrasive media.
