High Temperature Type Electro Magnetic Flow Meter with 130 / 150 / 180
1. Introduction
MLF electromagnetic Flowmeter works according to Faraday's law of electromagnetic induction and is composed of sensors and converters. Used to measure the electrical conductivity of liquids or solids. In general, its electrical conductivity should be greater than 5 μ S / cm (the electrical conductivity of tap water and raw water is about 100 ~ 500 μS / cm), can also be used to measure various media such as acid, alkali, salt water, pulp or pulp. But these media cannot contain large amounts of magnetic materials and bubbles.
MLF electromagnetic Flowmeter is an instrument for measuring liquid fluidity. It is widely used in flow measurement in metallurgy, chemical industry, paper making, environmental protection, petroleum, textile, food, urban management, waterworks and other industries.

4. Selection of Electrode Materials
Electrode Material | Main Performance |
316L | Good resistance to the corrosion of nitric acid, <5% sulfuric acid under room temperature, acetic acid, alkaline fluid, sulfite under certain pressure, seawater and scetic acid, etc. It can be widely used in petrochemical urea, vinylon. |
Hb | Good resistance to the all the concentration of hydrochloric acid below the boiling point, also resistance tothe corrosion of non-oxidizing acid, alkali, salt like sulfuric acid phosphoric acid hydrofluoric acid, organic acids. |
Hc | Resistance to the corrosion of oxidizing acids like metric acid, mixed acid. The mixture of chromium acid and sulfuric acid, and salts of oxidative, like Fe3+, Q3+, and some other oxidants, like hypochlorite salt solution higher than normal tmperature and seawater. |
Ti | Resistant to corrosion by seawater, various chlorides, hypochlorites, oxidizing acids (including fuming nitric acid), organic acids or bases, but not by pure reducing acids (such as sulfuric acid and hydrochloric acid). However, if the acid contains oxidants (such as nitric acid, Fe3+, Q3+), the corrosion resistance will be reduced. |
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. |
