Melan Brand MLF Model Electromagnetic Flow Meter with PTFE Liner
1. Introduction
The MLF electromagnetic flowmeter works according to Faraday's law of electromagnetic induction and consists of a sensor and a converter. Used to measure the conductivity of liquids or solids. Under normal circumstances, its conductivity should be greater than 5μS/cm (the conductivity of tap water and raw water is about 100-500μS/cm), and it can also be used to measure acids, alkali, brine, pulp or pulp and other media. But these media cannot contain a lot of magnetic substances 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, water plant and other industries.
2. Quick Details
1). It is high resistance, fast response design can make undistorted collection of weak signal and fast response to the flow changes. Its range rate can reach 100:1.
2) MLF electromagnetic flowmeter is explosion-proof design.
3) Function of low conductivity measurement.
4) There are nine language(Chinese, English, Korean, Polish, Turkish, French and Portuguese language) options to meet the needs of different customers.
5) It has the function of self-regulation and self-examination.
6) Different outputs are optional: Hart,RS485 Profibus,4-20mA, frequency, pulse.
3. Selection of Liner Material
| Liner Material | Main Performance | Application |
| PTFE | 1 The most stable chemical properties in plastics, resistant to boiling hydrogen chloride and sulfuric acid, nitric acid, aqua regia, strong bases and various organic solvents, but not resistant to the corrosion of chlorine trifluoride, high temperature nitrogen trifluoride, liquid fluorine, liquid oxygen and ozone. 2 Low wear resistance. 3 Low negative pressure resistance. | 1. -25~140℃ 2. Strong corrosion medium, like strong acid and alkali 3. Healthcare medium |
| CR | Oil proof, solvent resistance, oxidatite resistance and the resistance to the erosion of common medium like acid, alkali, salt, etc. | 1. ＜80℃ 2. Be able to measure sewage and mud |
| 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 resistance, hydrochloric acid, acetic acid, oxalic acid, ammonia, phosphoric acid and 50% sulfuric acid, sodium hydroxide, potassium hydroxide 2 Avoid strong oxidants | 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 |
4. 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 below boiling point of hydrochloric acid, but also resistant to non-oxidizing acids, alkalis, sulphuric acid, phosphoric acid, hydrofluoric acid, organic acid corrosion. |
| Hc | Corrosion resistance to oxidizing acids, such as nitric acid, mixed acids. A mixture of chromic acid and sulphuric acid, oxidizing salts, such as Fe3 plus, Q3 plus, and other oxidants, such as a mixture of hyalphate solutions and seawater above normal temperatures. |
| Ti | Resistant to corrosion of seawater, various chlorides, hyalphates, oxidizing acids (including smoke nitric acid), organic acids or alkalis, but not pure reduced acids (e.g. sulphuric acid, hydrochloric acid). However, if the acid contains oxidants (e.g. nitric acid, Fe3, Q3), corrosion resistance is 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. |
