Abstract: the correct selection of electromagnetic flow meter scale electrode technique information produced by excellent flow meter, flow meter manufacturer to offer you the quotation.
based on different media, there were a few multiple electrodes, for users at the scene of the according to the medium, can choose a more durable: electromagnetic electrode containing molybdenum stainless steel (
Nitrate, room temperature < 5% of sulfuric acid, phosphoric acid, formic acid, boiling.
More flow meter manufacturers choose model price quote you are welcome to inquire, the following is the correct selection of electromagnetic flowmeter electrode tip the details of the scale.
Electromagnetic flowmeter based on different media, there were a few multiple electrodes, for users at the scene of the according to the medium, can choose a more durable: electromagnetic electrode containing molybdenum stainless steel (
Nitrate, room temperature < 5% of sulfuric acid, boiling phosphoric acid, formic acid, alkali solution, under certain pressure of sulfurous acid, water, acetic acid hartz hartz alloy alloy C B (
Sea water, salt water titanium (
The sea, all kinds of chloride and hydrochloric acid, chloride oxidizing acid (
Including fuming nitric acid)
, organic acid, alkali tantalum (
Except hydrofluoric acid, fuming sulfuric acid and alkali of the rest of the chemical substances, including the boiling point of hydrochloric acid, nitric acid and sulfuric acid platinum (< 175 ℃
All kinds of acid, alkali, salt, not including aqua regia electromagnetic flowmeter is another department: how to properly choose lining material shall be according to the measured medium erosion resistance, abrasion resistance and temperature to choose lining materials.
Natural rubber (
1, good flexibility, abrasion resistance and break 2, generally weak acid and weak base erosion resistance measuring water, sewage, acid rubber (
Resistant to temperature of hydrochloric acid, acetic acid, oxalic acid, ammonia, phosphoric acid, and 50% of sulfuric acid, sodium hydroxide, potassium hydroxide, but not resistant to strong oxidizer erosion test of neoprene (acid, alkali, salt solution
1, good elasticity, high pull force, good wear-resisting function 2, generally low concentration of acid and alkali resistant, salt solution, but not the oxidation resistance of medium < 80 ℃;
For water, sewage and mud and slurry polyurethane rubber (
1, excellent wear-resisting function 2, acid, alkali, neutral functional differential < 40 ℃ test strong wear of coal slurry, mud and slurry polytetrafluoroethylene (
1, resistance to boiling hydrochloric acid, sulfuric acid, nitric acid and aqua regia, strong alkali and a variety of organic solvents and wear-resisting function good, 2 poor adhesion function -
Concentration measurement, strong alkali, strong corrosive solution and health class medium above is all there is in this article, you are welcome to inquire me factory flowmeter selection, quotation, etc.
