Factory special inspection of electromagnetic flow meter

Abstract: The factory-specific inspection information of electromagnetic flowmeters is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. Changzhou Chengfeng Instrument Intelligent Electromagnetic Flowmeter is developed based on a standardized manufacturing system. Its advanced design concept ensures the high precision and high reliability of the product. Compared with the old electromagnetic flowmeter, it has high measurement accuracy and reliability. Strong and stable. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the details of the special inspection articles for electromagnetic flowmeters. The instrument intelligent electromagnetic flowmeter is developed based on the standardized manufacturing system. Its advanced design concept ensures the high precision and high reliability of the product. Compared with the old electromagnetic flowmeter, it has high measurement accuracy and strong reliability. It has the advantages of good stability, complete functions and long service life. We will do special testing for each electromagnetic flowmeter that leaves the factory, as follows: 1. Electrode contact resistance: measure the liquid contact resistance value of the electrode spoon, which can indirectly evaluate the general appearance of the electrode and the lining layer without removing the flow sensor from the pipeline. Helps to analyze the cause of the error. 2. Polarization voltage of the electrodes: use the 2V DC range of the digital multimeter to measure the polarization voltage between the two electrodes and the ground respectively (the electromagnetic flowmeter can be measured without power failure or power failure). Measuring the polarization voltage between the electrode and the liquid will help to determine whether the problem of zero point instability or output shaking is caused by the electrode being contaminated or covered. 3. Determination of signal cable interference. In order to determine whether the zero point change is affected by the interference potential of the signal cable, it is necessary to determine the approximate range of the interference and the level of influence on the electromagnetic flowmeter. The signal cable is disturbed by external electrostatic induction and electromagnetic induction, which will cause the zero point of the electromagnetic flowmeter to change. 4. Determine the flow direction of the stray current in the pipeline, and sometimes find the source of the stray interference in the pipeline is upstream or downstream of the flow sensor, so as to reduce the search range and try to reduce or eliminate the influence of stray current interference. Electromagnetic flowmeter, a domestic high-end flowmeter brand, takes customer demand as the first priority, and puts quality first, so that customers can use it with confidence. High precision, durable, long service life, low failure rate and good after-sales service. Efforts are made to develop new technologies, improve product performance, use high-quality materials, and be meticulous about product quality. , Only do high-quality products, customer satisfaction is our driving force. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory. 'Special factory inspection of electromagnetic flowmeters'
