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 conductivity of liquid or solid. In general, its conductivity should be greater than 5μs/cm (tap water and raw water conductivity is about 100 ~ 500μs/cm), and it can also be used to measure acid, alkali, brine, pulp or pulp and other media. However, these media cannot contain a large amount of magnetic substances and bubbles.
MLF electromagnetic flowmeter is an instrument for measuring liquid fluidity. Widely used in metallurgy, chemical industry, paper making, environmental protection, petroleum, textile, food, urban management, water plant and other industries.
2. Features
MLF electromagnetic flowmeter is explosion-proof design.
Low conductivity measurement function.
There are nine language options to meet the needs of different customers.
It has self-regulation function and self-test.
Different outputs are optional: Hart, RS485, Profibus, 4-20mA, frequency, pulse.

4. Selection of Liner Material
| Liner Material | Main Performance | Application |
| PTFE | 1. Have the most stable chemical properties in plastic and resistance to boiling hydrochlor and sulfuric acid, nitric acid aqua regia, strong alkali, and all kinds of organic solvents, but can not resist the corrosion of chlorine trifluoride, high temperature nitrogen trifluoride, liquid fluorine, liquid oxygen and ozone. 2. Low abrasion 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. Good resistance to room temperature, 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 |
5. 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 | 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. |
6. Instrument Testing & 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 give corresponding tips in the lower right corner of the screen.
