Breif Introduction:

MTF 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.
 

Instrument Maintenance and repair

a) Sensor installation site should be consistent with the section four

requirements, Please keep the housing clean and tidy;

b)Transmitter should be placed in a clean, ventilated, dry place;

c)Need to inspect every two years, for high precision users, instrument

need to be submitted to censorship.

          Reminding

The selection of the sensor diameter is not the same as the diameter of pipe.This option

applies to the following:

A.for Low flow velocity in the pipe and the stable flow rate, to meet the requirements of the instrumentation on the flow rate range,we should increase the flow rate of partial area and

select the sensor diameter smaller than the pipe diameter ,and install another different -

diameter pipe before the sensor.

B.In terms of the price, for the magnetic flow meter with large diameter, the larger diameter

you want, you higher price you will pay; for the low flow rate in the pipe and stable parameter,

the selection of small diameter would be better. It will not only make the meter work in good condition but also reduce the cost.

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 Acetic acid, etc. It can be widely used in the petrochemical, urea, vinylon.
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.
Ti	Resist the corrosion of seawater, various chlorides,hypochlorite, oxidizing acid(like su-lfuric acid, hydrochloric acid). But if acid includes oxidants(like nitric acid,Fe+++,Q+++),the corrosion resistance will decrease.
Ta	Good corrosion resistance similar to glass. Resist the corrosion of chemical medium(including hydrochloric acid and fuming sulfuric acid),but can not be used for Sodium hydroxide fluid.
Pt-Ir	Have good corrosion resistance of all acid, and can resist the corrosion of alkali, all salt except Aqua regia, ammonium salt and few other medium.
Tungsten Carbide	For pulp and sewage, good resistance to solid particle interference.
