Chemical Liquid Electromagnetic Flow Meter EMF Equipment with SS316L Electrode
1. Introduction
1. 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.
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 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 the boiling point of hydrochloric acid, but also resistant to non-oxidizing acid, alkali, sulfuric acid, phosphoric acid, hydrofluoric acid, organic acid corrosion. |
Hc | Resistant to the corrosion of oxidizing acid, such as nitric acid and mixed acid. The mixture of chromic acid and sulfuric acid, oxidized salts, such as Fe3+, Q3+, and other oxidants, such as the mixture of hypochlorite solution and seawater at higher than normal temperature. |
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. |
