Paper Industry Electromagnetic Flow Meter High PerformanceInsertion Type
 
 
Abstract:

    MTF electromagnetic flow meter, composed of sensor and converter, works based on

Faraday’s law of electromagnetic induction. 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 mediums like acid, alkali, saline solution,paper pulp,ore pulp and so on.

But these mediums can’t contain a lot of magnetic materials and bubbles.

Storage precautions

After the shipment arrival, if the instrument is planed to store for a certain time, the followings
should be paid attention to:
A. It should be packed by its original package and kept same as the shipment package.
B. The storage place should take the following reference:
a. Avoid rain and wind.
b. Avoid impact
c. Don’t open the wire box for sensors connection to keep it dry in order not to affect future
normal operation
d. Atmosphere temperature, humidity and air pressure:

Atmosphere temperature:-20℃~+60℃
Relative humidity:5%~90%
Air pressure:86-106Kpa

Installation location precautions

The installation location is chosen according to the following requirements, ensuring the stable
and continuous operation of instruments.
Atmosphere temperature: avoid large temperature change and sunshine, if some thermal radiation
in the installation location, the thermal insulation and ventilation should be applied.
Air condition: avoid strongly corrosion and explosive gas in the installation location
(non-explode-resistant instrument)

Change adapter direction

It is not recommended to change the adapter direction by users, if it is necessary to change, please
contact service center.

Product application scope

The insert-type electromagnetic flow-meter is composed of sensors and adapter, using for
measuring conductive liquid. During measurement, conductivity is required to be more than 5μ
s/cm, and water, sewage, acid and alkali and so on could be measured.

Product component

One set of PMF insert-type electromagnetic flow-meter is composed of sensors and adapter. Two
different types are designed, according to safety class and parameter configuration, which are
sensor and adapter in one unit type and sensor and adapter separate type.
The sensor and adapter connection by shield cable is adopted in the separate type installation, to
make one set of electromagnetic flow-meter, illustrated as follow. The parameters could be fixed
according to user requirement and production value after manufacturing, which is suitable to inner
water occasion.

The corrosion resistance of the electrode material

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 Acetic acid, etc. It can be widely used in the petrochemical, urea, vinylon.
HB	Good resistance to the all the concentration of hydrochloric acid below the boiling point, also resist the corrosion of non-oxidizing acid, alkali, salt like sulfuric acid phosphoric acid hydrofluoric acid, organic acids.
HC	Resist the corrosion of oxidizing acids like metric acid, mixed acid, the mixture of chromium acid and sulfuric acid, and salts of oxidative, like Fe+++,Q+++,and some other oxidants, like hypochlorite salt solution higher than normal temperature and seawater.
