Instrument characteristic

?

- - - -
# Low consumption. |
# Good interchangeability of the converter, it is easy to have the accuracy without remark the real flow. |
# Wide ranges. |
# Empty pipe diagnosis automatically. |
# Both cone and line seal method are used in sealing the electrodes to make sure there is no leaks. |
# The input impedance of the converter is more than 1012ohms,it protects the sensor from fouling, it is good for measuring the low conductivity medium. |
# EMC of flow meter comply with IEC61000-1995 standard. |
# Due to the advantages of electromagnetic flow meter,it is widely used in various industries,and the preferred instrument for liquid flow measuring. |

Strength of Metlan

?

?

After nearly ten years of sustainable development, target at the Chinese market, Metlan

?

continuously invest in the product designing,research and manufacturing.We develop a supply

?

chain of production,warehouse,quality,sales.Also we have created our own production,business

?

model and explored a unique way of spot supplying from scratch,from small to large,from weak to

?

strength so that we can keep the promise to deliver the goods.Your visit and valuable advice are

?

our forward motivation.

The corrosion resistance of the electrode material(Only for reference, detailed in appendix)

- - - -
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. |
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. |
