Integrated Type Electromagnetic Flow Meter SS Material with Liner
Material of Rubber / PTFE / PFA / FEP / F46
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:
5). It is the first domestic company that adopts the function of
saving settings before delivery,which can avoid the loss of the
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 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.|
|Hc||Resistance 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
|Ti||Resistance 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.|
|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
|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
