Electromagnetic Flow Meter Of Acid Flow Meter Type

Electromagnetic Flow Meter of acid flow meter type

    Electromagnetic flow meter is a kind of high performance, high reliability flowmeter, which is widely used in petroleum, chemical industry, food, electricity, steel, paper making, metallurgy, water supply and drainage, petrochemical, medicine industry, etc.

Electromagnetic Flow Meter of acid flow meter type

Its advantage:

1 . Can be used not only in general process test,but also in the measurement of pastry liquids,like cement grout,paper pulp etc.

2 . There is no movable parts in the electromagnetic flowmeter, no loss pressure , simple structure, woke reliable;
3 . The measurement accuracy is not affected by the change of the measured medium’s pressure, density (including liquid-solid two-phase),temperature, viscosity and other physical parameter;
4 . Moisture proof and waterproof performance is good. Suit for setting up and being used underground or wet environments;
5 . Compare with other flowmeter, its advantage : big measurement range , low demand in straight pipe, high accuracy;
6 . Low power consumption, one set flowmeter power consumption less than 20W.

Electromagnetic Flow Meter of acid flow meter type

Selection of Electrode Materials:
NO.Electrode materialCorrosion resistance
1316LMeasuring water, sewage or organic acid or inorganic acid of minor corrosive medium.
2HB/HCResistant to corrosion of oxidizing acid such as nitric acid, mixed acid, chromic acid and sulfuric acid, or a mixed medium of corrosion, but also resistant to salts of the oxidation as Fe + + +, Cu + +, or the other oxidant-containing corrosion. Such as hypochlorous acid alkaline solution is higher than normal temperature or sea water corrosion
3TiApplicable in seawater, various chloride and hypochlorite, chlorinated acids (including fuming nitric acid), organic acid, alkali, etc.
Do not resistant to the pure reduction acid (such as sulfuric acid, hydrochloric acid) corrosion. However, if an acid containing an oxidizing agent (such as nitric acid and containing Fe + + +, Cu + + ions in the medium) the corrosion is greatly reduced.
4Tantalum(Ta)Having strong resistance to corrosive mediums that is similar with glass.
Almost applicable in all chemical mediums except for hydrofluoric acid, fuming sulfuric acid and alkali (including the boiling point of hydrochloric acid, nitric acid and sulfuric acid below 175 ℃). It has not any resistant to corrosion in alkali.
5Stainless steel covered with tungsten carbideApplicable in mediums of non-corrosive and low abrasion.
6Platinum-iridiumAlmost be applicable in all chemical mediums except for aqua for this, ammonium salt.
