Detailed introduction of the components of the electromagnetic flow meter

Abstract: The detailed introduction information of the components of the electromagnetic flow meter is provided by the excellent flow meter and flow meter production and quotation manufacturers. The intelligent electromagnetic flowmeter designed and developed by Changzhou Liangbang Instrument is developed on the basis of 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 the High precision, yes. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is a detailed introduction to the components of the electromagnetic flowmeter. The intelligent electromagnetic flowmeter designed and developed by our company is developed based on the 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, It has the advantages of strong reliability, good stability, complete functions and long service life. The structure of electromagnetic flowmeter is mainly composed of magnetic circuit system, measuring conduit, electrode, shell, lining and converter. Below we will introduce the specific functions and technical parameters of these components in detail 1. Shell: made of ferromagnetic materials, it is the outer cover of the distribution system excitation coil, and isolates the interference of external magnetic fields. 2. Measuring catheter: its function is to let The conductive liquid to be tested passes through. In order to make the magnetic flux be shunted or short-circuited when the magnetic field line passes through the measuring conduit, the measuring conduit must be made of materials with non-magnetic conductivity, low electrical conductivity, low thermal conductivity and certain mechanical strength. Plastic, aluminum, etc. 3. Magnetic circuit system: its function is to generate a uniform DC or AC magnetic field. The DC magnetic circuit is realized by using a magnet, its advantage is that the structure is relatively simple, and it is less disturbed by the AC magnetic field, but it is easy to polarize the electrolyte liquid in the measuring catheter, so that the positive electrode is surrounded by negative ions, and the negative electrode is surrounded by positive ions. Surrounding, that is, the polarization phenomenon of the electrodes, and leads to the increase of the internal resistance of the two electrodes, thus seriously affecting the normal operation of the instrument. When the diameter of the pipe is large, the magnet is correspondingly large, bulky and uneconomical, so the electromagnetic flowmeter generally adopts an alternating magnetic field, and is generated by the excitation of a 50HZ power frequency power supply. 4. Electrode: Its function is to draw out the induced potential signal proportional to the measured value. The electrodes are generally made of non-magnetic stainless steel and are required to be flush with the lining so that the fluid can pass unobstructed. Its installation position should be in the vertical direction of the pipeline to prevent sediment from accumulating on it and affecting the measurement accuracy. 5. Converter: The induced potential signal generated by the liquid flow is very weak and is greatly affected by various interference factors. The function of the converter is to amplify and convert the induced potential signal into a unified standard signal and suppress the main interference signal. Its task is to amplify and convert the induced potential signal Ex detected by the electrode into a unified standard DC signal. 6. Lining: There is a complete electrical insulating lining on the inner side of the measuring conduit and the sealing surface of the flange. It directly contacts the liquid to be measured, and its function is to increase the corrosion resistance of the measuring conduit and prevent the induced potential from being short-circuited by the wall of the metal measuring conduit. Lining materials are mostly corrosion-resistant, high-temperature-resistant, wear-resistant PTFE plastics, ceramics, etc. The electromagnetic flowmeter produced by Shiliangbang Instruments, we are a domestic high-end flowmeter brand, and can provide customized services to meet customer needs first, quality first, so that customers can use it with confidence. The reputation of Liangbang electromagnetic flowmeter in the industry and customer feedback are satisfactory: high precision, durability, long service life, low failure rate, and good after-sales service. These are the customer's evaluation of us, the customer's affirmation is the driving force for our progress, we strive to develop new technologies, improve product performance, use high-quality materials, be meticulous about product quality, and ensure a 100% pass rate for production testing. Quality products, customer satisfaction is our driving force. The electromagnetic flowmeters developed and produced by us are exquisite in materials, high in quality and exquisite in technology. The qualified rate of continuous sampling inspection is 100%, the service life of each high-precision electromagnetic flowmeter is 5-8 years, and the failure rate is extremely low. After long-term use, it can still work stably after failure and maintenance. Maybe you think this is justified. Indeed, Liangbang people also understand this, so they strive to be comparable to imported products in terms of quality. These are unmatched by some low-priced products in the current market. After impetuous production and putting into the market, they will be damaged and cannot be repaired after 1-2 years of use. From the perspective of environmental protection, it will undoubtedly produce a large amount of industrial waste. In terms of after-sales service, we provide 24-hour gold service in the most humanized mode, so that customers can buy with confidence. Liangbang is a real domestic high-end electromagnetic flowmeter The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
