How to correctly choose the material of electromagnetic flow meter scale

Abstract: how to correctly choose the material of electromagnetic flow meter scale information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. How to correctly choose the material of electromagnetic flowmeter electromagnetic flowmeter, as a kind of common flow measuring instrument, the selection of its material is also an important factor. Parts in contact with the medium because of electromagnetic flowmeter, and only the interior of the electrode and the measuring tube,. More flow meter manufacturers choose model price quote you are welcome to inquire, here is how to correctly choose the material of electromagnetic flow meter scale article details. How to correctly choose the material of electromagnetic flowmeter electromagnetic flowmeter, as a kind of common flow measuring instrument, the selection of its material is also an important factor. Parts in contact with the medium because of electromagnetic flowmeter, and only the interior of the electrode and the measuring tube, so according to the characteristics of different media, need to choose the right electrode material and lining. A, on the choice of electrode material in general electrode material points in the following: 1. Stainless steel ( 0Cr18Ni12Mo2Ti) 。 Suitable for nitric acid, less than 5% of the sulfuric acid at room temperature, boiling phosphoric acid, formic acid and alkali solution, under certain pressure of sulfurous acid, water and acetic acid. 2. Hartz alloy, hartz alloy C B. Can be used for sea water and brine. 3. Titanium. Seawater, apply to all kinds of chloride and hydrochloric acid, chloride oxidizing acid ( Including fuming nitric acid) , organic acid, alkali, etc. 4. 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 < 175 ℃ sulfuric acid can be used. 5. Platinum. Can be used in all kinds of acid, alkali, salt, but not including aqua regia. Second, about the choice of lining material of electromagnetic flowmeter another important material choice is: how to properly choose lining material. Must pay attention to is, should according to the measured medium erosion resistance, abrasion resistance and temperature to choose lining materials. 1. Rubber. Has the very good elasticity, high breaking strength, wear-resisting function is good, the erosion of general weak acid weak base, can be measured, such as water, sewage and mud and slurry. 2. Polyurethane. Has excellent abrasion resistance, acid resistance, alkali function is poor, can measure neutral strong wear of coal slurry and the mud and slurry. 3. Ptfe. Resistance to boiling hydrochloric acid, sulfuric acid, nitric acid and aqua regia, strong alkali and a variety of organic solvents, good wear-resisting function, poor adhesion function. Above is the electromagnetic flowmeter, the choice of material of different medium has different characteristics, not necessarily choose zui expensive, choosing the right is the economic and durable. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
