Electro Magnetic Flow Meter Ex-proof JIS 10K Flange Low Flow
1. Introduction
MLF electromagnetic flow meter, composed of sensor and converter, works based on Faraday’s law of electromagnetic induction law. It is used to measure electrical conductivity of liquid or solid. Generally, the electrical conductivity should be over 5υS/cm(electrical conductivity of tap water, raw water is about 100～500υS/cm),It can also be used to measure various media like acid, alkali, saline solution, paper pulp or pulp and so on. But these media can’t contain a lot of magnetic materials and bubbles.
MLF electromagnetic flow meter is a kind of instrument which is used for measuring the flow conductivity liquid. The meter is widely used in flow measuring of Metallurgy, Chemical Industry, Paper Industry,Environmental Protection, Oil Industry, Textile Industry, Food Industry and City Administration, Water Works,etc.

5.Selection of Electrode Materials
| Electrode Material | Main Performance |
| 316L | Good corrosion resistance to nitric acid, less than 5% corrosion of sulfuric acid, acetic acid, alkaline liquid, sulfite, seawater and acetic acid under certain pressure at room temperature, and can be widely used in petrochemical urea, vinylon and so on |
| Hb | Good resistance to hydrochloric acid with concentration lower than boiling point and corrosion of non-oxidizing acid, alkali, sulfuric acid, phosphoric acid, hydrofluoric acid and organic acid. |
| Hc | Corrosion of oxidizing acids, such as nitric acid, mixed acids. A mixture of chromic acid and sulfuric acid, oxidized salts, such as Fe3,Q3, and some other oxidants, such as a mixture of hypochlorite solution and seawater above normal temperature. |
| Ti | Resistance the corrosion of seawater, various chlorides, hypochlorite, oxidizing acid(including fuming nitric acid), and organic acid or alkali, but don't be resistance to the corrosion of pure reducint acid(like sulfuric acid, hydrochloric acid). But if acid includes oxidants(like nitric acid, Fe3+, Q3+), the corrosion resistance will decrease. |
| Ta | Good corrosion resistance similar to glass. Resistance to the corrosion of chemical medium(including hydrochloric acid and fumiing sulfuric acid), but can not be used for sodium hydromide fluid. |
| Pt-Ir | Have good corrosion resistance of all acid, and can be resistance to the corrosion of alkali, all salt except aqua regia, ammonium slat and few other medium |
| Tungsten Carbide | For pulp and sewage, good resistance to solid particle interference. |
