MLF Series Electromagnetic Flow Meter Designed for Measurement of Conductive Liquids
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.
2. Features
MLF electromagnetic Flowmeter is explosion-proof design.
function of low conductivity measurement.
There are 9 language options to meet the needs of different customers.
Have self-regulation function and self-examination.
different outputs are optional: hart, RS485 Profibus ,4-20 mA, frequency, pulse.

| PU | 1. Very good abrasive resistance, flexibility. 2. Low acid and alkali resistance. | 1. ＜65℃ 2. Neutral strong abrasion resistance medium |
| Hard Rubber | 1 Room temperature, hydrochloric acid, acetic acid, oxalic acid, ammonia, phosphoric acid and 50% sulfuric acid, sodium hydroxide, potassium hydroxide 2 Avoid strong oxidizing agents | 1. ＜80℃ 2. General acid, alkali, salt solution |
| PFA | 1. Can be used for most corrosive medium like acides, alkalis, and strong oxidant. 2. High material strength, resistance to aging, better than PTFE, EFP in high temperature 3. Injection molding for higher negative pressure | 1. 40~180℃ 2. Strong corrosion medium, like strong acid and alkali 3. Healthcare mdium |
| FEP(F46) | 1. Hydrophobicity and non-viscous 2. Corrosion resistance is inferior to PFA 3. Negative pressure | 1. 40~180℃ 2. Strong corrosion medium, like strong acid and alkali 3. Healthcare mdium |
5. Selection of Electrode Materials
| Electrode Material | Main Performance |
| 316L | Good corrosion resistance of nitric acid, at room temperature <5% sulfuric acid, acetic acid, alkaline liquid, a certain pressure of sulphate, seawater, acetic acid and other corrosion, can be widely used in petrochemical urea, veline and so on. |
| Hb | Good resistance to all concentrations of hydrochloric acid below boiling point, as well as non-oxidizing acid, alkali, sulfuric acid, phosphoric acid, hydrofluoric acid and organic acid. |
| 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 | Corrosion resistance of oxidizing acids, such as nitric acid and mixed acid. A mixture of chromic acid and sulfuric acid, oxides, such as Fe3+,Q3+, and other oxidants, such as a mixture of hypochlorite solution above normal temperature and seawater. |
| 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. |
