Electromagnetic flowmeter DN100, when many friends first come into contact with this kind of products, they may wonder what parameter is this? Some buyers and intermediary friends who are new to contact will have such doubts. Let me introduce the electromagnetic Flow meter DN100. Electromagnetic flowmeter DN100 is the main representative of the electromagnetic flowmeter when selecting the type. The caliber is 100. DN refers to the nominal diameter. DN100 means that the nominal diameter of the steel pipe is 100 mm. The DN100 pipe is also called a four-inch tube. This is in the electromagnetic flowmeter A parameter that will be used in the selection.  The electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. It is used to measure the volume flow of conductive liquids with a conductivity greater than 5μS/cm. It is an induction meter for measuring the volume flow of conductive media. In addition to measuring the volume flow of general conductive liquids, it can also be used to measure the volume flow of strong corrosive liquids such as strong acids and alkalis and uniform liquid-solid two-phase suspension liquids such as mud, mineral pulp, and paper pulp. It is widely used in the flow measurement of petroleum, chemical industry, metallurgy, textile, papermaking, environmental protection, food and other industrial departments and municipal management, water conservancy construction, river dredging and other fields. Like other flowmeters, although the electromagnetic flowmeter has a measuring range ratio of 30:1, which is higher than that of vortex flowmeters and differential pressure flowmeters, it also has limitations. Many customers often use it when setting the meter. Compared with the water meter, I think it can measure very low flow velocity. Under normal circumstances, it can only measure 0.3m/s. The electromagnetic flowmeter is difficult to measure correctly if the flow velocity is lower than this. Therefore, it is necessary to clarify the flow range ratio at the beginning of the order. When ordering, it is not possible to order according to the original pipe diameter. It is best to set the gauge diameter according to your actual flow.   Electromagnetic flowmeter DN100 is a common parameter in the selection stage of electromagnetic flowmeter, but when choosing the caliber, many friends have to determine the caliber of the meter according to the actual flow rate. Therefore, we must understand the flow range clearly in the early stage. Therefore, the caliber is determined according to this flow range, and the type cannot be selected according to the original pipeline caliber, so there will be errors.   Under what kind of flow rate will the electromagnetic flowmeter DN100 choose this caliber? Let me introduce it to you. Under the condition that the range Q has been determined, the size of the flowmeter diameter D can be determined according to the range of the above-mentioned flow rate V, and its value is calculated by the following formula:   Qu003dπD²V/4  Q: flow rate (㎡/h) D: pipe inner diameter V : Flow rate (m/h)  The range Q of the DN100 electromagnetic flowmeter should be greater than the expected maximum flow value, and the normal flow value should be slightly greater than 50% of the flowmeter's full scale scale.   Electromagnetic flowmeter DN100, this is the parameter requirement that needs to be used in the selection stage of electromagnetic flowmeter. Other selection parameters of electromagnetic flowmeter also need to pay attention to: measuring medium, power supply method, installation method, electrode type and lining material. Kaidi is a manufacturer of electromagnetic flowmeters. It has the following characteristics in the production of electromagnetic flowmeters:    first point: high accuracy (0.5 level comprehensive accuracy)    second point: wide measurement (chemical sewage, tap water, fire water, mud and pulp, etc., Almost all working conditions are met)    third point: anti-interference (standard grounding screw and grounding three electrodes, on-site anti-interference is significantly improved)    fourth point: long life (standard stainless steel body, solid and durable, strong corrosion resistance)    above The main purpose is to show you what is the electromagnetic flowmeter DN100? There are also some parameters and specifications that need to be paid attention to in the selection of electromagnetic flowmeters. I must have a certain understanding.
