Industrial Irrigation Electromagnetic Flow Meter with DN15 - DN2000 Pipeline Diameter​


1. Introduction

MLF electromagnetic flow meter, composed of sensor and converter, works based on Faraday’s law of electromagnetic induction law. It is used to measure electrical conductivity of liquid or solid. Generally, the electrical conductivity should be over 5υS/cm(electrical conductivity of tap water, raw water is about 100~500υS/cm),It can also be used to measure various media like acid, alkali, saline solution, paper pulp or pulp and so on. But these media can’t contain a lot of magnetic materials and bubbles.

MLF electromagnetic flow meter is a kind of instrument which is used for measuring the flow conductivity liquid. The meter is widely used in flow measuring of Metallurgy, Chemical Industry, Paper Industry,Environmental Protection, Oil Industry, Textile Industry, Food Industry and City Administration, Water Works,etc.


2. Quick Details

1). It is high resistance, fast response design can make undistorted collection of weak signal and fast response to the flow changes. Its range rate can reach 100:1.

2). It has the function of low conductivity measurement.

3). It has the consistency of converter’s interchange, which can avoid input parameters repeatedly.

4). Wide range of power supply mode is available (DC: 18V-36V/AC: 85V-265V).

5). It is the first domestic company that adopts the function of saving settings before delivery,which can avoid the loss of the parameters.

6). It adopts the international leading excitation technology, which circuit is simple, stable,and reliable.

7). It has the function of infrared remote control and button operation so as to make the operation more convenient.

8). It provides the function of zero correction of sensor and automatic zero adjustment.

9). It has Chinese, English, Korean, Polish, Turkish, French and Portuguese languages for option to satisfy different customers’ requirements.

4. Selection of Liner Material

Liner MaterialMain PerformanceApplication
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

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. 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 MaterialMain Performance
316LGood 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.

HcResistance 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.
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.
