1. Introduction
The MLF electromagnetic flowmeter works according to Faraday's law of electromagnetic induction and consists of a sensor and a transducer. Used to measure the conductivity of a liquid or solid. In general, its conductivity should be greater than 5μS/cm (tap water, raw water conductivity of about 100 ~ 500μS/cm), can also be used to measure acid, alkali, salt water, pulp or pulp and other media. However, these media should not contain large amounts of magnetic material and air bubbles.
MLF electromagnetic flowmeter is a kind of instrument to measure liquid fluidity. Widely used in metallurgy, chemical industry, paper making, environmental protection, petroleum, textile, food, urban management, water plant and other industries flow measurement.
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.
Self-regulating function and self-checking.
Different outputs are optional: Hart, RS485,Profibus, 4-20mA, frequency and pulse.

4. Selection of Liner Material
| Liner Material | Main Performance | Application |
| PTFE |
1 It has the most stable chemical properties in plastics, resistant to boiling hydrogen chloride and sulfuric acid, nitric acid, aqua regia, strong alkali and various organic solvents, but not resistant to chlorine trifluoride, high temperature nitrogen trifluoride, liquid fluorine, and liquid oxygen And ozone corrosion. 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 Resistance to room temperature, hydrochloric acid, acetic acid, oxalic acid, ammonia, phosphoric acid and 50% sulfuric acid, sodium hydroxide and 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 |
5. Selection of Electrode Materials
| Electrode Material | Main Performance |
| 316L |
Good corrosion resistance of nitric acid, sulfuric acid, acetic acid, alkaline liquid at room temperature < 5%, sulfite, seawater, acetic acid and other corrosion under certain pressure, can be widely used in petrochemical urea, vinylon 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 |
The corrosion resistance of oxidizing acids, such as nitric acid and mixed acids. A mixture of chromic acid and sulfuric acid, oxidizing salts such as Fe3+, Q3+, and other oxidizing agents such as a mixture of hypochlorite solutions and sea water at above-normal temperatures. |
| 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. |
6. Instrument Detection & Maintenance
Electromagnetic flowmeter has self-diagnosis function. In addition to power supply and hardware circuit faults, the system also alarms other faults in general use. These messages are prompted in the bottom right corner of the screen.
