Sensor size selection

 

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.

 


 

Warning of installing the different-diameter pipe

 

To avoid affecting too much the distribution of the velocity field and the measuring

 

accuracy, The center of the cone angle of different diameter pipe should not be

 

greater than 15,thus we could regard the different-diameter pipe as part of the

 

straight pipe.

 

 

 


Selection of Electrode materials:

 

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.
