Electromagnetic flow meter developed rapidly with the development of electronic technology

Abstract: With the rapid development of electronic technology, the electromagnetic flow meter information is provided to you by excellent flow meter and flow meter production and quotation manufacturers. Electromagnetic flowmeter is a new type of flow basin torsion measuring instrument developed rapidly with the development of electronic technology in the 1960s. It is made according to Faraday's law of electromagnetic induction, and is used to measure the volume flow of the current from the conduction. Due to its unique advantages, it has been widely used. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of electromagnetic flowmeters that have developed rapidly with the development of electronic technology. Electromagnetic flowmeter is a new type of flow basin torsion measuring instrument developed rapidly with the development of electronic technology in the 1960s. It is made according to Faraday's law of electromagnetic induction and is used to measure the volume flow of conductive current. Due to its unique advantages, it has been widely used in the lateral flow of various conductive liquids in industry. For example, it can be used to measure various corrosive substances such as acids, children, and salts, various volatile and explosive media, various industrial sewage, pulp, mud, etc. The main features of the electromagnetic flowmeter are: ① The transmitter of the electromagnetic flowmeter has a simple structure, no moving parts, and no throttling parts that hinder the flow of the fluid, so when the fluid passes through, it will not cause any additional music loss. At the same time, it will not cause problems such as wear, blockage, etc. VA I is especially suitable for ore pulp with solid grain, sewage and other liquid-solid two-phase fluids, and various dry slurries, etc. Fol samples, due to It has no moving parts in structure, so it can be made of electrodes by attaching a corrosion-resistant insulating lining and selecting corrosion-resistant materials, which has good corrosion resistance and can be used for the measurement of various corrosive media. ②Electromagnetic flowmeter is a kind of volume flow meter, in the process of measuring, it is not affected by the temperature, dryness, density and conductivity (within a certain range) of the measured medium. Therefore, electromagnetic flowmeter After being calibrated by water, it can be used to measure the current liabilities of other conductive liquids without additional correction. ③The range of electromagnetic flowmeters is extremely wide, and the range ratio of the same electromagnetic flowmeter can be 1:100. In addition, the electromagnetic flowmeter is only proportional to the average flow velocity of the measured medium, and has nothing to do with the flow state (laminar flow or prime flow) under the axisymmetric distribution. ④The electromagnetic flowmeter has no mechanical inertia and has a sensitive response. It can measure the instantaneous pulsating flow and has good linearity. Therefore, the measured mother signal can be directly converted into a standard signal output linearly with a converter, which can be indicated locally or transmitted over a long distance. Although the electromagnetic current meter has the above-mentioned excellent characteristics, it still has some shortcomings, so that it is limited in use. The main points are as follows. ①Electromagnetic current meter cannot be used to measure and record gas, vapor and liquid containing large gas. ②Electromagnetic current M meter can not be used to measure liquid medium with very low conductivity, the conductivity string of the liquid medium on the side should not be lower than 10-' (S/cm), which is equivalent to the conductivity of distilled water. Products or organic solvents are powerless. ③ Due to the limitation of the temperature of the insulating lining material of the measuring tube, the current industrial electromagnetic flow gold meter cannot measure the high temperature and high pressure flow of the disk. ③Due to the limitation of the temperature of the insulating lining material of the measuring tube, the current industrial electromagnetic flowmeter cannot measure the high temperature and high pressure flow. ④The electromagnetic flow meter is affected by the flow velocity distribution. Under the condition of axisymmetric distribution, the flow basin signal is proportional to the average flow velocity. Therefore, there must be a certain length of straight pipe sections before and after the electromagnetic flowmeter. ⑤ The electromagnetic flow meter is susceptible to the influence of external electromagnetic interference. To sum up, the electromagnetic flowmeter has many unique advantages, and there are also many shortcomings that cannot be ignored. In order to have a deeper understanding of the various performances of the electromagnetic flowmeter, let’s discuss the working principle, structure, and interference of the electromagnetic flowmeter. The production and anti-interference measures, the influence of the reserve factors on the browsing site, etc., are introduced in depth. The above is the whole content of this article.
