Product structure of sewage electromagnetic flow meter

Abstract: Sewage electromagnetic flow meter product structure information is provided by excellent flow meter and flow meter manufacturers and quotation manufacturers. The role of the converter is to analyze the structure of the price product. The structure of sewage electromagnetic flowmeter: 1. Shell The electromagnetic flowmeter is made of ferromagnetic material, which is the outer cover of the excitation coil of the distribution system and isolates the interference of the external magnetic field. 2,. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the product structure of sewage electromagnetic flowmeters. The role of the sewage electromagnetic flowmeter converter is to analyze the structure of the price product. The structure of the sewage electromagnetic flowmeter: 1. The shell electromagnetic flowmeter is made of ferromagnetic material, which is the outer cover of the excitation coil of the distribution system and isolates the interference of the external magnetic field. 2. The induced potential signal generated by the converter is very weak and is greatly affected by various interference factors. The function of the converter is to amplify and convert the induced potential signal into a unified standard signal and suppress the main interference signal. Its task is to amplify and convert the induced potential signal Ex detected by the electrode into a unified standard DC signal. 3. Lining There is a complete electrical insulating lining on the inner side of the measuring conduit and the sealing surface of the flange. It directly contacts the liquid to be measured, and its function is to increase the corrosion resistance of the measuring conduit and prevent the induced potential from being short-circuited by the wall of the metal measuring conduit. Lining materials are mostly corrosion-resistant, high-temperature-resistant, wear-resistant PTFE plastics, ceramics, etc. 4. The function of the magnetic circuit system is to generate a uniform DC or AC magnetic field. The DC magnetic circuit is realized by using a magnet, its advantage is that the structure is relatively simple, and it is less disturbed by the AC magnetic field, but it is easy to polarize the electrolyte liquid in the measuring catheter, so that the positive electrode is surrounded by negative ions, and the negative electrode is surrounded by positive ions. Surrounding, that is, the polarization phenomenon of the electrodes, and leads to the increase of the internal resistance of the two electrodes, thus seriously affecting the normal operation of the instrument. When the diameter of the pipe is large, the magnet is correspondingly large, bulky and uneconomical, so the electromagnetic flowmeter generally adopts an alternating magnetic field, and is generated by the excitation of a 50HZ power frequency power supply. 5. The function of the measuring catheter is to let the measured conductive liquid pass through. In order to make the magnetic flux be shunted or short-circuited when the magnetic field line passes through the measuring conduit, the measuring conduit must be made of materials with non-magnetic conductivity, low electrical conductivity, low thermal conductivity and certain mechanical strength. Plastic, aluminum, etc. 6. The function of the electrode is to draw out the induced potential signal proportional to the measured value. The electrodes are generally made of non-magnetic stainless steel and are required to be flush with the lining so that the fluid can pass unobstructed. Its installation position should be in the vertical direction of the pipeline to prevent sediment from accumulating on it and affecting the measurement accuracy.
