Kate Instruments intelligent electromagnetic flowmeter is developed based on a standardized manufacturing system. Its advanced design concept ensures the high precision and high reliability of the product. Compared with the old electromagnetic flowmeter, it has high measurement accuracy and strong reliability. , good stability, complete functions, long service life and so on. As a commonly used flow measuring instrument, the choice of flow meter material is also an important factor. In the electromagnetic flowmeter, only the electrode and the inside of the measuring tube are in contact with the medium. Therefore, according to the characteristics of different mediums, appropriate electrodes and lining materials need to be selected. 1. Relevant electrode selection Usually electrodes are divided into the following materials: 1. Stainless steel (0Cr18Ni12Mo2Ti). It is suitable for nitric acid, sulfuric acid, phosphoric acid, alkali solution of less than 5% at room temperature, etc. 2. Hastelloy. Can be used for sea water and salt water. 3. Titanium. Suitable for seawater, various chloride and hypochlorite hydrochloric acid, oxidizing acids (including fuming nitric acid), organic acids, alkalis, etc. 4. Tantalum. In addition to hydrofluoric acid, fuming sulfuric acid, alkali, other chemical media, including boiling point hydrochloric acid, nitric acid and <175 ℃ sulfuric acid can be used. 5. Platinum. Can be used for various acids, bases, salts, but does not contain aqua regia. Second, how to choose the right lining material for the choice of lining material. It must be noted that the lining material should be selected according to the corrosiveness, abrasiveness and temperature of the measured medium. 1. Rubber. It has excellent elasticity, high breaking force, good wear resistance, resistance to the usual weak acid and weak alkali corrosion, and can measure water, sewage, mud and ore pulp, etc. 2. Polyurethane. It has excellent wear resistance, poor acid and alkali resistance, and can measure coal slurry, mud and ore slurry with neutral and strong wear. 3. Teflon. Resistant to hydrochloric acid, sulfuric acid, nitric acid, concentrated alkali and various organic solvents, with good wear resistance and poor adhesion. The above is about the selection of electromagnetic flowmeter materials. Different media have different characteristics. It is not necessary to choose the most expensive one. It is really economical to choose the appropriate one. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
