dn800 intelligent electromagnetic flowmeter

Many small partners have never touched large-caliber intelligent electromagnetic flowmeters before. For example, the dn800 intelligent electromagnetic flowmeter is a large-caliber intelligent electromagnetic flowmeter. The dn800 of the dn800 intelligent electromagnetic flowmeter means that the inner diameter of the flowmeter is 800mm. When the pipeline flow to be measured is large, a large-caliber intelligent electromagnetic flowmeter such as the dn800 intelligent electromagnetic flowmeter needs to be used.　　 Having finished talking about the meaning of the caliber of the dn800 intelligent electromagnetic flowmeter, we need to introduce the second half of the dn800 intelligent electromagnetic flowmeter, what is the intelligent electromagnetic flowmeter. The intelligent electromagnetic flowmeter is manufactured according to Faraday's law of electromagnetic induction. It is an induction meter used to measure the volume flow of conductive media in the tube. The meter generally uses the embedded technology of the single-chip microcomputer to realize digital excitation. The CAN field bus is used on the Internet, which is a relatively common flow meter. The price of intelligent electromagnetic flowmeters is closely related to the selection of intelligent electromagnetic flowmeters, so what should be paid attention to when selecting electromagnetic flowmeters? Let’s first look at the sensor part 1, flow rate, and determine how much scale flow meter should be selected according to the maximum flow rate. Determine the caliber of the flowmeter according to the flow rate and the size of the industrial pipe. Generally, the flow meter that is consistent with the pipeline is selected. 3. According to the characteristics of the measured medium, the lining of the flow meter is selected. Such as temperature, corrosivity, whether there may be negative pressure in the pipeline, etc. Generally linings are PTFE, soft rubber, hard rubber, PFA, ceramics and so on.　　 4. Choose the material of the measuring electrode according to the characteristics of the medium. Generally there are 304, 316, Hastelloy, titanium, tantalum and so on.　　5. Select the pressure level of the flanges connected on both sides according to the pressure level of the process piping.　　6. u200bu200bSelect the protection level. If the sensor is completely underwater, you need to select IP68. 　　 There is also the transmitter part.　　 1. According to the requirements of the installation location, determine whether to choose an integrated or split type.　　2, what type of output are needed, 4-20 mA signal, Hart, Profibus PA, FF, etc.　　 3. Whether explosion-proof requirements are required. Determine the explosion-proof level. The signal of the intelligent electromagnetic flowmeter is weak, in fact, don't worry too much, because after the electromagnetic flowmeter is installed, it can operate normally for a long time even if there is no regular maintenance. After that, maintenance and daily inspection and maintenance are required. . Not receiving the signal or the signal is too weak are minor problems, more common. So don't worry about it if it happens, check according to the following points, generally you can quickly find the cause of the failure and solve the problem in time.　　 1. When the signal of the intelligent electromagnetic flowmeter is weak, first confirm whether the pipeline is full of fluid.　　 2. If the pipe is too close to the wall during installation, consider installing the probe on the diameter of the pipe with an inclined angle, instead of installing it on the diameter of the horizontal pipe. At this time, the Z method should be used to install the probe.　　 3. Carefully select the dense part of the pipeline, and ensure that it is fully polished and bright, and install the probe with a suitable lotus mixture. 4. Move each probe carefully and orderly and slowly near the installation point to find the maximum signal point to prevent the ultrasonic beam from reflecting out of the expected area due to scaling on the inner wall of the pipe or due to local deformation of the pipe. It is an installation point that can receive a strong signal. 5. If the inspection finds that there is dirt on the inner wall of the pipeline, it is necessary to use the method of beating on the metal pipeline with serious inner wall scale to make the scaled part fall off or crack. However, it should be noted that this method may sometimes cause fouling and The gap created between the inner walls does nothing to help the transmission of ultrasonic waves. I believe that after reading the content of the appeal, the friends have already understood the concept of dn800 intelligent electromagnetic flowmeter. If you want to better understand the knowledge of electromagnetic flowmeter, in addition to reading more books, you also need to go into the use of electromagnetic flowmeter. Scenes, so that we can more intuitively and concretely recognize the role of electromagnetic flowmeters in our lives. Then the editor suggests that you can find some famous dn800 smart electromagnetic flowmeter manufacturers, such as Kaidi Sensing, etc. They will have a dedicated engineer to help you choose options and quotes.
