Qiqihar electromagnetic flowmeter

With the development of China's automation industry in recent decades, domestic instrument and meter manufacturers have sprung up all over China like bamboo shoots after a rain. Take electromagnetic flowmeters as an example. At present, there are several industrial clusters in China, such as Kaifeng, Henan, Qingdao, Shandong, Huaian, Jiangsu, and Guangdong. However, in Qiqihar, there is no flow meter industry. Therefore, if you are in Qiqihar and need Qiqihar electromagnetic flowmeters, then you have to set your sights on the national market. Before understanding, you must first understand the electromagnetic flowmeter. Electromagnetic Flowmeters (EMF for short) is a new type of flow measurement instrument that developed rapidly with the development of electronic technology in the 1950s and 1960s. Electromagnetic flowmeter is an instrument that uses the principle of electromagnetic induction to measure the flow of conductive fluid based on the electromotive force induced when the conductive fluid passes through an external magnetic field. Because the measurement accuracy is high and the requirements for the measurement medium are not very high, electromagnetic flowmeters are currently widely used in petroleum, chemical, metallurgy, textile, paper, environmental protection, food and other industrial sectors and municipal management, water conservancy construction, and river dredging. Flow measurement in other fields. If you need to buy an electromagnetic flowmeter in Qiqihar, pay special attention to it, and be sure to find a real electromagnetic flowmeter manufacturer to order it. Because electromagnetic flowmeters are widely used in industrial occasions, the measured medium is basically some sewage, or chemical products, acid or lye, etc. If the quality of the electromagnetic flowmeter does not pass, it will be safe to human life. Cause a great threat. The first is the caliber and pressure rating of the electromagnetic flowmeter. The smart electromagnetic flowmeters currently on the market can be divided into several levels according to the caliber. Take the conventional pipeline electromagnetic flowmeter, its caliber is often related to its nominal pressure, generally like a small caliber, for example, the electromagnetic flowmeter between DN10-DN150, the pressure can be 4.0MPA; and the larger the caliber, The smaller the withstand voltage it can withstand. For example, the pipeline between DN200-DN600 can withstand a pressure of 1.6MPA. Some large-diameter pipes, such as between DN700 and DN1200, can withstand a pressure of 1.0MPA. In addition, more pressure resistance and smaller pipe diameters need to be customized from the manufacturer, and ordinary distributors or agents cannot do it. The second is the accuracy of the electromagnetic flowmeter. The accuracy of conventional electromagnetic flowmeters can generally be 0.5 or 1.0. The higher the accuracy, the more accurate the test and the smaller the error. This is especially important in some occasions that require industrial control. Then there are the linings and electrodes of the electromagnetic flowmeter. The correct selection method of the lining material of the electromagnetic flowmeter should be based on the corrosiveness, abrasiveness and temperature of the measured medium. The lining material can be divided into polytetrafluoroethylene (F4/PTFE), neoprene rubber (CR), and polyurethane rubber. (PU), Teflon (F46/FEP), copolymer (PFA) are mainly several kinds. The electrodes are divided into 316L stainless steel electrodes, titanium electrodes, Ha B electrodes, Ha C electrodes, tantalum electrodes, tungsten carbide electrodes and so on. There is also a more important selection factor, which is the temperature resistance class. The temperature resistance grade can be divided into three grades: T1/T2/T3. The temperature resistance grade is also related to the material of the lining. Generally speaking, CR/PU for ≤60℃; PTEP/FEP for ≤120℃; and PFA for ≤200℃. The rest is the selection of power supply mode and output signal. The commonly used power supply methods are 24VDC and 220AC, and lithium batteries can also be used for power supply. The output signal can be 4-20mA, RS485 output, pulse signal, HART output, etc. I believe that the editor has introduced so much, you must know the main points that you need to pay attention to when selecting Qiqihar electromagnetic flowmeters, right? If some readers feel that it is really troublesome to confirm so many parameters and choose the model by yourself. Then the editor suggests that you can search for some famous electromagnetic flowmeter manufacturers, such as Kaidi Sensing, etc. Their LDG-MIK series electromagnetic flowmeters are very useful, and they will have a dedicated engineer to help you choose options and quotes. Of it.
