Selection of sewage electromagnetic flow meter and other flow meters

Abstract: The selection information of sewage electromagnetic flowmeter and other flowmeters is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. Sewage electromagnetic flowmeter is one of sewage flowmeter products. It is different from common sewage flowmeter products in that it has electromagnetic function. Sewage electromagnetic flowmeter has all the characteristics of sewage flowmeter, and it also has its own structure. Simple. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following are the details of the selection articles of sewage electromagnetic flowmeters and other flowmeters. Sewage electromagnetic flowmeter is one of sewage flowmeter products. It is different from common sewage flowmeter products in that it has electromagnetic function. Sewage electromagnetic flowmeter has all the characteristics of sewage flowmeter, and it also has its own structure. Simple, firm and reliable, long service life and so on. The sewage electromagnetic flowmeter is an instrument that measures the volume flow of conductive liquids based on Faraday's law of electromagnetic induction. The conductive liquid flows in the non-magnetic measuring tube perpendicular to the magnetic field, and an induced potential proportional to the flow is generated in the direction perpendicular to the flow direction.“Fleming's right hand rule”, and its value is as follows. Let the volume flow of the liquid be E= (4 kB/πD) qv. Since the first industrial application of sewage electromagnetic flowmeter in China in the late 1950s, it has been used and developed rapidly in flow measurement in the 1970s and 1980s. The working principle of electromagnetic flowmeter is based on Faraday's law of electromagnetic induction, that is, the measured medium flows perpendicular to the direction of the magnetic field lines, so an induced electromotive force EX is generated in the direction perpendicular to both the medium flow and the magnetic field lines. ) is proportional. The sewage electromagnetic flowmeter is not affected by external factors such as temperature, pressure, viscosity, and weight, and there is no pressure loss in the shrinkage or protruding parts inside the measuring tube. In addition, the initial signal detected by the flow element is a precise signal with the average flow rate of the fluid. A linearly varying voltage, which is independent of other properties of the fluid, has great advantages. According to the characteristics of sewage with large flow changes, impurities, low corrosiveness, and certain electrical conductivity, electromagnetic flowmeters are a good choice for measuring the flow of sewage. It has compact structure, small volume, convenient installation, operation and maintenance. For example, the measuring system adopts intelligent design and the overall sealing is strengthened, so that it can work normally in harsh environments. The electromagnetic flowmeter with neoprene lining and molybdenum-containing stainless steel (OCrI8Ni12Mo2Ti) electrode can be selected to meet the requirements of sewage flow measurement. During the production of a smelter, a large amount of industrial sewage will be generated due to the needs of the production process, and the sewage treatment plant must monitor the flow of sewage. In the previous design, many flow meters used vortex flowmeters and orifice flowmeters. In practical application, it is found that the deviation between the measured flow display value and the actual flow is large, and the deviation of the electromagnetic flowmeter is greatly reduced. The cost and installation cost of sewage electromagnetic flowmeter and general sewage flowmeter products are low, especially suitable for the measurement of large and medium-diameter pipeline flow. It adopts advanced processing technology, solid-state packaging, long life, and good measurement accuracy and stability. . The above is the whole content of this article.
