Selection of split electromagnetic flowmeter

Many users with purchase experience should know that electromagnetic flowmeters can be divided into two types: one-piece type and split type. How is this distinguished? Simply put, the integrated electromagnetic flowmeter means that the flowmeter body and the meter are connected together, and the split electromagnetic flowmeter, the body and the meter are separated. Many people may feel very confused about this. Why are electromagnetic flowmeters divided into two types, one-piece and one-piece? In fact, this is often caused by the complex working conditions of our site. In many conventional occasions, an integrated electromagnetic flowmeter may be required, which is also convenient for on-site readings. However, in some special occasions, such as high temperature, high altitude, or corrosive occasions, the meter head is easily corroded, and it is not easy for people to repair, and it is not easy to read. This gives birth to a split electromagnetic flowmeter. So, how can you make a cost-effective split electromagnetic flowmeter? First of all, as a user, you must have a basic concept of split electromagnetic flowmeters. In addition, for the selection of other parameters of split electromagnetic flowmeters Requirements, you must also understand roughly.　　 First is the diameter of the electromagnetic flowmeter. Conventional pipeline electromagnetic flowmeters can generally achieve DN15-DN1200 in diameter, while large-diameter ones are more suitable for plug-in electromagnetic flowmeters. Theoretically, the diameter can be DN200-DN2000.　　Secondly, electromagnetic flowmeters can be divided into several levels according to different accuracy levels. At present, the conventional pipeline electromagnetic flowmeters on the market generally have the same accuracy level. Generally, they can achieve 1.0 and 0.5. The accuracy can be said to be very high. It is used in some occasions that require high accuracy. More, such as dosing control, flow measurement and so on. In addition, for some relatively large calibers, plug-in electromagnetic flowmeters are often used for measurement, while plug-in types, due to different installation methods and larger flow ranges, have relatively poor accuracy. Generally, it can only be level 1.5, or level 2.5.　　 Then the lining and electrode 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), chloroprene 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.　　 Another important selection factor 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 what you need to pay attention to when selecting the split electromagnetic flowmeter? If some readers think that so many parameters need to be confirmed, it is really troublesome to choose the model by yourself. . The editor suggests that you can search for some well-known manufacturers of split electromagnetic flowmeters, such as Kaidi Sensing. Their Kaidi LDG-MIK series split electromagnetic flowmeters are very useful and will be more popular in the market. They will have a dedicated engineer to help you with options and quotations.
