1. Introduction
The MLF electromagnetic flow meter is based on Faraday's law of electromagnetic induction and consists of sensors and converters. 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 to 500μs/cm), can also be used to measure acids, alkali, brine, pulp or pulp and other media. However, these media must not contain large amounts of magnetic substances and bubbles.
MLF electromagnetic flow meter is an instrument for measuring liquid flow. Widely used in metallurgy, chemical, paper, environmental protection, petroleum, textiles, food, urban management, water plants and other industries flow metering.
2. Features
MLF electromagnetic flowmeter is explosion-proof design.
The function of low conductivity measurement.
There are 9 language options to meet the needs of different customers.
There are self-regulating functions and self-checking.
Different outputs are optional: Hart, RS485,Profibus, 4-20mA, frequency, pulse.
3. 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 |
4. Selection of Electrode Materials
| Electrode Material | Main Performance |
| 316L | Good corrosion resistance to nitric acid, less than 5% corrosion of sulfuric acid, acetic acid, alkaline liquid, sulfite, seawater and acetic acid under certain pressure at room temperature, and can be widely used in petrochemical urea, vinylon 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, hypochlorite, oxidizing acids (including fuming nitric acid), organic acids or bases, but not pure reductive acids (e.g., sulfuric acid, hydrochloric acid) etc. but if the acid contains oxidants (such as 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 Detection & Maintenance
Electromagnetic flow meters have a self-diagnosis function. In addition to power and hardware circuit failures, the system also alerts to other faults in general use. This information is prompted in the lower right corner of the screen.
1 Maintenance and repair
a) The sensor installation site should comply with section IV requirements, please keep the housing clean;
b) The transmitter should be placed in a clean, ventilated and dry place;
c) The instrument needs to be checked every two years and for high-precision users, the instrument needs to be submitted for review.
2 Transport and storage
a) The instrument must be packed before transport and handled with care.
b) Storage sites must be dry and ventilated to avoid the erosion of corrosive gases, and the ambient temperature should not be too low or too high
c) Storage time should preferably not exceed three years.
3 Out-of-the-box inspection
a) The package cannot be opened with a heavy hammer and care should be taken not to damage the instrument
b) Check the contents carefully according to the packing slip.
