Several elements should be paid attention to in the initial selection of intelligent electromagnetic flowmeter

Abstract: The information on several elements that should be paid attention to in the initial selection of intelligent electromagnetic flowmeters is provided by excellent flowmeter and flowmeter manufacturers. Introduction: Although we have also talked about some selection methods and steps of intelligent electromagnetic flowmeters before, in this article, we mainly discuss some small details that need to be paid attention to in the selection process of intelligent electromagnetic flowmeters; 1. The characteristics of intelligent electromagnetic flowmeters Accuracy class. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of several elements that should be paid attention to in the initial selection of intelligent electromagnetic flowmeters. Introduction: Although we have also talked about some selection methods and steps of intelligent electromagnetic flowmeters, in this article, we mainly discuss some small details that need to be paid attention to in the selection process of intelligent electromagnetic flowmeters; 1. The accuracy grade determines the accuracy of the intelligent electromagnetic flowmeter produced by our factory is divided into±0.3%,±0.2%,±There are three grades of 0.5%. For the production of alumina or other control of flow only, the accuracy of selection should not be too high. It is not economical to choose high accuracy, so general accuracy can be selected; 2. Diameter , Determination of flow rate and flow range The intelligent electromagnetic flowmeter has the advantage of a wide range. If it is to measure the flow rate of alumina slurry, the general flow rate is 1.5~3m/s, and the sensor diameter of the intelligent electromagnetic flowmeter is generally the same as The diameter of the pipe should be kept the same. For the selection of abrasive fluids such as pulp, the commonly used flow rate can be selected, generally 2~3m/s, the purpose is to reduce the wear of the electrode lining; 3. The lining of the intelligent electromagnetic flowmeter For some corrosive fluids, fluoroplastic lining should be used when selecting lining. The so-called fluoroplastic lining is the polytetrafluoroethylene that we often use, which is characterized by excellent corrosion resistance and temperature resistance up to -40 ℃ ~+180℃, but the disadvantage is that it is not wear-resistant, and ceramic lining can be used for abrasive media. Ceramic lining also has the advantages of corrosion resistance, high temperature resistance, wear resistance, etc., but it also has the disadvantage that it cannot adapt to the severe temperature Therefore, if the lining of the electromagnetic flowmeter is not properly selected, it is likely that the lining will be deformed in actual work, which will affect the normal operation of the flowmeter. For material selection, the first thing to consider is the corrosiveness of the electrode to the measurement medium, and the second is to determine whether a chemical reaction on the surface of the electrode will occur. If the selection is improper, chemical reactions such as electrode passivation and oxidation will occur. Some commonly used electrodes The material can be summarized by referring to the following table: For the selection of intelligent electromagnetic flowmeter, the selection of this small detail is very important for the later use of electromagnetic flowmeter. If an improper selection is made, the measurement error will be large in the light of the light, and the instrument will not work in the heavy case. , so users should pay attention to the selection of 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.

In the past few decades, customized level indicator production has increased because of the use of level gauge.
Serving others for customers a better life with level gauge for employees respect and opportunity.
Consistency and simplicity go hand in hand. That means aligning KAIDI with the right platforms, speaking to the right customers with the right message, and selling the right idea.
Guangdong Kaidi Energy Technology Co., Ltd. sells customized level indicator and yet their focus on operational excellence and mastery of distributed manufacturing facilities customized level indicator has made them the dominant player in the space.
In the boundless Chinese market, there are a number of enterprises that provides customized level indicator level gauge of their own brand over the years, but few have won more support from customers on the international stage than KAIDI.
