Chengfeng Instrument Intelligent electromagnetic flowmeter is developed based on the standard manufacturing system. Its advanced design concept ensures high precision and high reliability of the product. Compared with the old electromagnetic flowmeter, it has high measurement accuracy and reliability. Strong, stable, functional, long life and other advantages. As a commonly used flow measurement instrument, the choice of flowmeter material is also an important factor. In the electromagnetic flowmeter, the part that comes into contact with the medium is only the inside of the electrode and the measuring tube. Therefore, depending on the characteristics of the different media, a suitable electrode and lining material must be selected. First, the choice of electrodes The electrode is usually divided into the following materials: 1. Stainless steel (0Cr18Ni12Mo2Ti). Suitable for nitric acid, less than 5% sulfuric acid, phosphoric acid, alkali solution, etc. at room temperature. 2. Hastelloy. It can be used in seawater and salt water. 3. Titanium. Suitable for seawater, various chlorides and hypochlorinated hydrochloric acid, oxidizing acids (including fuming nitric acid), organic acids, alkalis, etc. 4. Hey. In addition to hydrofluoric acid, fuming sulfuric acid, other chemical media other than alkali, including the boiling point of hydrochloric acid, nitric acid and <175 ° C sulfuric acid can be used. 5. Platinum. Can be used for various acids, bases, and salts, but does not contain aqua regia. Second, the choice of lining material How to choose the right lining material. It must be noted that the lining data should be selected based on the corrosivity, wear and temperature of the measured medium. 1. Rubber. It has excellent elasticity, high breaking force, good abrasion resistance, resistance to common weak acid and weak alkali, and can measure water, sewage, mud and pulp. 2. Polyurethane. It has excellent abrasion resistance, poor resistance to acid and alkali, and can measure coal slurry, mud and pulp that have strong neutral wear. 3. Teflon. Resistant to hydrochloric acid, sulfuric acid, nitric acid, concentrated alkali and various organic solvents, it has good abrasion resistance and poor bonding performance. The above is about the choice of electromagnetic flowmeter materials. Different media have different characteristics. It is not necessary to choose the most expensive ones, and the proper ones are selected to be truly economical.
