Abstract: the correct selection of electromagnetic flow meter scale electrodes and lining material information produced by excellent flow meter, flow meter manufacturer to offer you the quotation. Kate instrument intelligent electromagnetic flowmeter is based on a standard manufacturing system and development, its advanced design concepts to ensure the high precision and high reliability of the product, compared with the old electromagnetic flowmeter, it has high measurement precision, high reliability, good stability,. More flow meter manufacturers choose model price quote you are welcome to inquire, the following is the correct selection of electromagnetic flow meter scale electrodes and lining material article details. Kate instrument intelligent electromagnetic flowmeter is based on a standard manufacturing system and development, its advanced design concepts to ensure the high precision and high reliability of the product, compared with the old electromagnetic flowmeter, it has high measurement precision, high reliability, good stability, complete function, long life and other advantages. As a kind of common flow meter, flow meter material selection is also an important factor. Electromagnetic flowmeter, and the part in contact with the medium only the interior of the electrode and the measuring tube, so, according to the features of different media, choose suitable electrode material and lining. A choice, the electrode is usually electrode in the following materials: 1. Stainless steel ( 0Cr18Ni12Mo2Ti) 。 Suitable for nitric acid, at room temperature is less than 5% of the sulfuric acid, phosphoric acid, alkali, etc. 2. Hartz alloy. Can be used in sea water and brine. 3. Titanium. Seawater, apply to all kinds of chloride and hydrochloric acid, chloride oxidizing acid ( Contains fuming nitric acid) , organic acid, alkali, etc. 4. Tantalum. Except hydrofluoric acid, fuming sulfuric acid and alkali of other chemical medium, containing 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 does not include the aqua regia. Second, for the selection of lining material how to choose suitable lining materials. Must pay attention to that should be on the basis of the measured medium corrosion resistance, wear resistance and temperature to choose lining materials. 1. Rubber. Has the very good elasticity, high breaking strength, wear-resisting function is good, usually the weak acid weak base of corrosion resistance, can measure water, sewage and mud and slurry, etc. 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. Hydrochloric acid, sulfuric acid, nitric acid, strong alkali resistance, and a variety of organic solvents, good wear-resisting function, poor adhesion function. This is about the electromagnetic flowmeter the choice of materials, different medium has different characteristics, must not choose zui expensive, choosing suitable to the real economy. Above is all there is in this article, you are welcome to inquire me manufacturer flowmeter selection, quotation, etc.
