Analysis of what may happen when the electromagnetic flow meter works

Abstract: The analysis information of the situation that may occur when the electromagnetic flow meter is working is provided by the excellent flow meter and flow meter manufacturers. Electromagnetic flowmeter is a kind of flow meter with high precision, high reliability and long service life. The measured fluid should not contain many ferromagnetic substances or bubbles, and the corresponding pressure should be selected according to the temperature, pressure, corrosiveness, abrasion and other characteristics of the measured fluid. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the analysis article details of what may happen when the electromagnetic flowmeter is working. Electromagnetic flowmeter is a kind of flow meter with high precision, high reliability and long service life. The measured fluid should not contain many ferromagnetic substances or bubbles, and the corresponding pressure grade, lining material, electrode material and instrument structure should be selected according to the temperature, pressure, corrosiveness, abrasion and other characteristics of the measured fluid. Common faults can be roughly divided into two categories: faults during commissioning (inadequate installation) and faults in normal operation. The main problem in installation: the sensor is installed in the high point of the pipeline where gas is easy to accumulate. Mounted on a top-down vertical pipe, some evacuation may occur. The back pressure of the sensor, the fluid is directly discharged into the large measurement tube and the non-full tube is formed. If you think about it from the perspective of the environment, it is mainly the interference of pipeline stray current, the interference of strong electromagnetic waves in space, and the magnetic field interference of large motors. Pipeline stray current interference can usually take good separate grounding protection, but in case of strong stray current, additional measures should be taken to insulate the flow sensor from the pipeline. Space electromagnetic wave interference is generally introduced through signal cables, usually single-layer or multi-layer. layer shield for protection. If small bubbles appear in the electromagnetic flowmeter, when the bubbles are larger, the output signal of the meter will fluctuate. When the base bubble is large enough to cover the entire electrode surface, the electrode circuit will be instantaneously disconnected as the bubbles flow through the electrode, causing the output signal to appear. Larger fluctuations, if it is to measure mixed media, enter the flow sensor for measurement before the mixing is even, and the output signal will also fluctuate. The electromagnetic flowmeter produced by the instrument is of superb quality and technology, and uses superior materials. The service life of each electromagnetic flowmeter is more than 5-8 years, and it can still work normally after a fault is repaired, which is undoubtedly a good manifestation from the perspective of environmental protection. In terms of after-sales service, the instrument provides 24-hour gold service in the most humanized mode, so as to truly make customers buy what they want and use them with confidence. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
