The electromagnetic flow meter only has cumulative amount, and the instantaneous flow is always zero. What is the reason?

Abstract: The electromagnetic flow meter has only the cumulative amount, and the instantaneous flow is always zero. The information on what causes it is provided by the excellent flow meter and flow meter manufacturers and quotation manufacturers. The electromagnetic flowmeters produced by Changzhou Chengfeng with the introduction of foreign advanced technology are divided into three types: integrated type, split type and plug-in type. It has obtained explosion-proof certification and was rated as a high-tech product in Jiangsu Province. It has high cost performance among peer products and has been favored by customers in many industries. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the article details of the reason why the electromagnetic flowmeter only has cumulative volume, and the instantaneous flow is always zero. The electromagnetic flowmeters produced by the introduction of foreign advanced technology are divided into three types: integrated type, split type and plug-in type. It has obtained explosion-proof certification and is rated as a high-tech product. It has high cost performance among peer products and has been well received by customers in many industries. The installation size can completely replace ABB's electromagnetic flowmeter. The electromagnetic flowmeter only has the cumulative amount, and the instantaneous flow is always zero. What is the reason? 1. The medium is not conductive. 2. There is flow in the pipeline but it is not full. 3. There is no flow in the electromagnetic flowmeter pipeline. 4. The electrode is covered and not in contact with the liquid. 5. The flow rate is less than the lower limit of flow cutoff set in the meter head. 6. The parameter settings in the header are incorrect. 7. The sensor is damaged. To avoid problems, you need to pay attention to the selection and installation of electromagnetic flowmeters: 1. First, clarify the measurement requirements of the unit. There are several measurement requirements, mainly: measurement medium, flow m3/h (minimum, working point, maximum) , Medium temperature ℃, medium pressure MPa, installation form (flange type, clamp type), etc. 2. Prerequisites for selecting electromagnetic flowmeter 1. The measured medium must be a conductive liquid (that is, the measured fluid is required to have a minimum electrical conductivity). 2. The measured medium should not contain a lot of ferromagnetic medium or a lot of bubbles. 3. The measurement principle of the electromagnetic flowmeter should be understood Also known as volume flow) is proportional to the voltage, the voltage signal is detected by two electrodes in direct contact with the fluid, and transmitted to the display through the cable, full Chinese menu operation, easy to use, simple to operate, easy to learn and understand. The flowmeter has digital communication signal output such as RS485, RS232, Hart and Modbus. (Optional) With self-test and self-diagnosis functions. The electromagnetic flowmeters produced are of superb quality and technology and are made of high-quality materials. The pass rate of continuous sampling inspection is 100%. The service life of each electromagnetic flowmeter is more than 5-8 years. It can still work normally after a fault is repaired. Maybe you think this is justifiable. It is true that Chengfeng also understands it. Comparable to imports. These are unmatched by some low-priced products in the current market. After the impetuous production and putting into the market, they will be damaged and cannot be repaired after 1-2 years of use. From the perspective of environmental protection, it is undoubtedly the production of a large amount of industrial waste. . 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.
