Online maintenance skills of plug-in electromagnetic flowmeter

Abstract: The online maintenance skills information of the plug-in electromagnetic flowmeter is provided by the excellent flowmeter and flowmeter production and quotation manufacturers. The measurement principle of the insertion electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. The measuring tube of the flowmeter is a short tube of non-magnetic conductive alloy lined with insulating material. Two electrodes are fixed on the measuring tube through the tube wall along the diameter of the tube. Its electrode tip and the inner surface of the lining. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the online maintenance skills article of the plug-in electromagnetic flowmeter. The measurement principle of the insertion electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. The measuring tube of the flowmeter is a short tube of non-magnetic conductive alloy lined with insulating material. Two electrodes are fixed on the measuring tube through the tube wall along the diameter of the tube. Its electrode tip is substantially flush with the inner surface of the liner. When the excitation coil is excited by the double-wave pulse, a working magnetic field with a magnetic flux density of B will be generated in the direction perpendicular to the axis of the measuring tube. At this time, if a fluid with a certain conductivity flows through the measuring tube. The electromotive force E is induced by the cutting magnetic field lines. The electromotive force E is proportional to the magnetic flux density B, and the product of the inner diameter d of the measuring tube and the average flow velocity v is measured. The electromotive force E (flow signal) is detected by the electrodes and sent to the converter through the cable. After the converter amplifies the flow signal, it can display the fluid flow, and can output pulse, analog current and other signals for flow control and regulation. Although the plug-in electromagnetic flowmeter is simple to operate and requires less maintenance, long-term use will still cause the electrodes to become dirty or worn. Therefore, to ensure the accuracy of the measurement, it is very necessary to regularly repair the insertion electromagnetic flowmeter. For plug-in electromagnetic flowmeters, the system must be shut down for each maintenance and the pipework must be drained before disassembly. If a failure occurs during abnormal maintenance, the disassembly and assembly of the insertion electromagnetic flowmeter will have a great impact on the continuous production efficiency. Therefore, an isolation ball valve can be installed on the mounting seat to realize online plugging and unplugging when the system is not running to ensure the continuous and stable operation of the system. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
