Electromagnetic flowmeter manufacturer

I believe that many small partners who do project contracting or project construction will have a better understanding of electromagnetic flowmeter manufacturers. Because every project of my friends, such as sewage treatment project, printing and dyeing plant renovation project, building air conditioning energy management, desulfurization and denitrification projects, all need to support electromagnetic flowmeters. Due to the different particularities of the project and equipment, the most urgent need for the electromagnetic flowmeter used is to find an electromagnetic flowmeter manufacturer. Because there will not be a single electromagnetic flowmeter at the site, if the project requires it, it must be a batch of electromagnetic flowmeters. If the electromagnetic flowmeter manufacturer is not found, and the electromagnetic flowmeter is bought carelessly, if there is a problem, then the problem Will be enlarged. So it’s very important to find a manufacturer of electromagnetic flowmeters! There are many electromagnetic flowmeters on the market now, but are you not a manufacturer of electromagnetic flowmeters? This needs a question mark? The electromagnetic flowmeter production workshop is also relatively large. At present, part of the electromagnetic flowmeter The flowmeter manufacturer is located in Kaifeng, Henan. From two reasons, the first is that Kaifeng has introduced foreign technology of electromagnetic flowmeters long ago. The technology started relatively early, and the old electromagnetic flowmeter technology is relatively mature. However, research and development capabilities need to be strengthened. Another point is that because Henan has a large land, a relatively large population, and low labor costs, the cost of the electromagnetic flowmeter production market is lower than that of other domestic technologically mature places, so it is also more suitable for the concentrated development of electromagnetic flowmeter manufacturers.　　 From the principle point of view of the magnetic circuit system: its role is to generate a uniform DC or AC magnetic field. The DC magnetic circuit is realized by permanent magnets. Its advantage is that the structure is relatively simple and the interference from the AC magnetic field is small, but it is easy to polarize the electrolyte liquid passing through the measurement catheter, so that the positive electrode is surrounded by negative ions, and the negative electrode is surrounded by positive ions. Enclosure is the polarization phenomenon of the electrodes, and causes the internal resistance between the two electrodes to increase, which seriously affects the normal operation of the meter. When the pipe diameter is large, the permanent magnet is correspondingly large, heavy and uneconomical. Therefore, the electromagnetic flowmeter generally uses an alternating magnetic field and is excited by a 50HZ power frequency power supply.　　Measuring catheter: Its function is to let the measured conductive liquid pass through. In order to make the magnetic flux shunt or short-circuit when the magnetic line of force passes through the measuring tube, the measuring tube must be made of non-magnetic, low electrical conductivity, low thermal conductivity and a certain mechanical strength material. Non-magnetic stainless steel, glass steel, high strength can be selected. Plastic, aluminum, etc.　　 Electrode: Its function is to draw out an induced electric potential signal proportional to the measured. Electrodes are generally made of non-magnetic stainless steel and are required to be flush with the lining so that the passage of fluid is not obstructed. Its installation position should be in the vertical direction of the pipeline to prevent sediment from accumulating on it and affecting the measurement accuracy.　　 Shell: It is made of ferromagnetic material, which is the outer cover of the excitation coil of the distribution system, and isolates the interference of the external magnetic field.　　 Lining: There is a complete electrical insulating lining on the inside of the measuring pipe and the flange sealing surface. It directly contacts the liquid to be measured, and its function is to increase the corrosion resistance of the measuring tube and prevent the induced potential from being short-circuited by the metal measuring tube wall. The lining materials are mostly corrosion-resistant, high-temperature-resistant, and wear-resistant polytetrafluoroethylene plastics, ceramics, etc.　　 Converter: The induced potential signal generated by the liquid flow is very weak and is greatly affected by various interference factors. The role 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.　　 The corresponding technology of Kaidi electromagnetic flowmeter is also relatively advanced, and the stability can still be depended on.
