High Temperature Type Electromagnetic Flow Meter with Modbus 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. 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 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 of oxidizing acids, such as nitric acid and mixed acid. A mixture of chromic acid and sulfuric acid, oxides, such as Fe3+,Q3+, and other oxidants, such as a mixture of hypochlorite solution above normal temperature and seawater.

Ti

Resistant to corrosion of seawater, various chlorides, hyalphates, oxidizing acids (including smoke nitric acid), organic acids or alkalis, but not pure reduced acids (e.g. sulphuric acid, hydrochloric acid). However, if the acid contains oxidants (e.g. nitric acid, Fe3, Q3), corrosion resistance is reduced.

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.
