Electromagnetic flow meter installation structure and caliber and electrode selection

Abstract: The information on the installation structure, diameter and electrode selection of electromagnetic flowmeters is provided by excellent flowmeter and flowmeter manufacturers. Electromagnetic flowmeter installation structure and caliber and electrode selection Installation structure The electromagnetic flowmeter host and sensor are assembled together to form an integrated electromagnetic flowmeter; or connected with the flow sensor through a signal cable to form a split electromagnetic flowmeter. Split. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the installation structure, diameter and electrode selection of electromagnetic flowmeters. Electromagnetic flowmeter installation structure and caliber and electrode selection Installation structure The electromagnetic flowmeter host and sensor are assembled together to form an integrated electromagnetic flowmeter; or connected with the flow sensor through a signal cable to form a split electromagnetic flowmeter. The split converter is mounted on the wall or on a stand. Diameter selection When the common flow rate of the measuring pipe exceeds 0.5 m/s, choose a flowmeter with the same diameter as the measuring pipe. Select a flowmeter with a diameter smaller than that of the measuring pipe in the following cases: the flow velocity in the measuring pipe is slow and cannot meet the measurement requirements of the flowmeter or its measurement accuracy cannot be met at this flow rate (to obtain relatively high accuracy, the lower limit of the flow rate should be greater than 1m /s). Electrode material selection 1. Stainless steel 316L: used for weak corrosive media such as industrial water, domestic water, sewage, neutral solutions and weak acids such as carbonic acid and acetic acid. 2. Titanium: resistant to corrosion by seawater, various chlorides and hypochlorites and many hydroxides. 3. Hastelloy C: Resistant to oxidative acids, such as nitric acid, mixed acid, a mixture of chromic acid and sulfuric acid. Also resistant to corrosion in oxidizing salts or other oxidizing environments. It has good corrosion resistance to seawater, alkaline solution and oxide solution. 4. Hastelloy B: It has good corrosion resistance to non-oxidizing acids and alkali salts such as sulfuric acid, phosphoric acid and hydrofluoric acid. 5. Tantalum: Except for hydrofluoric acid, it is resistant to corrosion by almost all chemical media. Because of its high price, it is only used for hydrochloric acid and concentrated sulfuric acid. 6. Tungsten carbide: It has excellent wear resistance and is specially used for abrasive media such as mud and pulp. The above is the whole content of this article.
