DN800 Large Diameter Electromagnetic Flow Meter with Lower And Upper Alarm


1. Introduction

MLF electromagnetic flowmeter 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. Generally, its conductivity should be greater than 5μS/cm (the conductivity of tap water, raw water is about 100~500μS/cm). it can also be used to measure various media such as acid, alkali, brine, pulp or pulp and other medium. But these medium can not contain a large number of magnetic substances and bubbles.

MLF electromagnetic flowmeter is an instrument to measure liquid fluidity. Widely used in metallurgy, chemical, paper, environmental protection, petroleum, textile, food, urban management, water plants and other industries of flow measurement.


2. Quick Details

MLF electromagnetic flowmeter is explosion-proof design.

Function of low conductivity measurement.

There are nine language options to meet the needs of different customers.

It has the function of self-regulation and self-examination.

Different outputs are optional: Hart,RS485 Profibus,4-20mA, frequency, pulse.

4. Selection of Liner Material

Liner MaterialMain PerformanceApplication
PTFE

2 Low wear resistance.

3 Low negative pressure resistance.

1. -25~140℃

2. Strong corrosion medium, like strong acid and alkali

3. Healthcare medium

CROil 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, hydrochloric acid, acetic acid, oxalic acid, ammonia, phosphoric acid and 50% sulfuric acid, sodium hydroxide, potassium hydroxide

2 Avoid strong oxidizing agents

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 MaterialMain Performance
316L

Good corrosion resistance of nitric acid, <5% sulfuric acid, acetic acid, alkaline liquid normal temperature, sulfite, seawater, acetic acid under certain pressure, 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

Corrosion of oxidizing acids, such as nitric acid, mixed acids. A mixture of chromic acid and sulfuric acid, oxidized salts, such as Fe3,Q3, and some other oxidants, such as a mixture of hypochlorite solution and seawater above normal temperature.

TiResistance 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.
TaGood 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-IrHave 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 CarbideFor pulp and sewage, good resistance to solid particle interference.
