Stainless Steel Separate Type Electromagnetic Flow Meter with RS485 Output


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. Features
The MLF electromagnetic flow meter is for explosive proof design.
It has the function of low conductivity measurement.
It has Chinese, English, Korean, Polish, Turkish, French and Portuguese languages languages for option to satisfy different customers’ requirements.
It has the function of self-adjustment and self-checking.
A variety of outputs are optional:Hart, RS485, Profibus, 4-20mA, Frequency, Pulse.


3. Application:

MLF electromagnetic flow meter is a kind of instrument,used for measuring the flow conductivity liquid, which 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.

5. 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
