Electromagnetic flowmeter can be divided into three types: integral type, split type and insertion type.Has made explosion-proof certification, was named the jiangsu province technology products, in the peer products, cost-effective, multiple industry customers get the praise, installation dimensions can completely replace the ABB electromagnetic flowmeter, in electromagnetic flowmeter selection, the choice of electrode material is particularly important, the following di chuan instrument for you to introduce some kind of electrode material and the applicable scope.

1.Stainless steel: used for industrial water, domestic water, sewage and other mildly corrosive medium, suitable for petroleum, chemical, steel and other industrial sectors and municipal, environmental protection and other fields.

2.Hardy alloy B: good corrosion resistance to hydrochloric acid of all concentrations below boiling point, as well as to non-chlorinated acid, alkali and non-oxidizing salt solution such as sulfuric acid, phosphoric acid, hydrofluoric acid, organic acid, etc.

Hartz alloy C: 3.3 the oxidation resistance and acid such as nitric acid, mixed acid, or a combination of chromic acid and sulfuric acid medium corrosion, oxidation resistance and salts such as Fe, "under, and the Cu" or with other antioxidant corrosion, such as higher than normal temperature hypochlorite solution, seawater corrosion of titanium sea water, all kinds of chloride and hypochlorite, oxidizing acid (including fuming sulfuric acid), organic acid, alkali corrosion.Less resistant to pure reducing acid (such as sulfuric acid, hydrochloric acid) corrosion, but if the acid contains oxidants (such as nitric acid, Fc++, Cu++), the corrosion is greatly reduced.

4.Tantalum: very similar to glass in its excellent corrosion resistance.Except for hydrofluoric acid, fuming sulfuric acid and alkali, it is almost resistant to corrosion by cutting chemical media (including hydrochloric acid at boiling point, nitric acid and sulfuric acid below 50℃).Diao in alkali;Corrosion resistant.

5.Platinum/titanium alloy: almost resistant to cutting chemical media, but not for aqua regia and ammonium salts.Stainless steel coated tungsten carbide is used in non-corrosive, highly abrasive media.
