Application of electromagnetic flow meter in corresponding industry

Abstract: The application information of electromagnetic flow meter in the corresponding industry is provided by excellent flow meter and flow meter manufacturers. With the development of China's urban economy, both domestic sewage and industrial sewage have a rapid growth trend, which makes the trend of water environment pollution and water environment quality decline intensified. Therefore, the state has strengthened investment in sewage treatment and construction. More flowmeter manufacturers select models and price quotations. You are welcome to inquire. The following is the application article details of electromagnetic flowmeters in the corresponding industries. With the development of China's urban economy, both domestic sewage and industrial sewage have a rapid growth trend, which makes the trend of water environment pollution and water environment quality decline intensified. Therefore, the state has strengthened investment in sewage treatment, built and put into operation a large number of sewage treatment plants, thereby improving our ecological environment. How to ensure that the water quality and quantity of sewage treatment meet the national discharge standards, which puts forward new requirements for the configuration and management of measuring instruments. At present, the electromagnetic flowmeter, a relatively accurate meter, is gradually popularized and popularized in sewage treatment plants. In the traditional automatic monitoring and information integration system of sewage treatment plants, electromagnetic flowmeters use 4-20mA (transmitting analog information) or 24VDC (transmitting switch information) signals for communication transmission. The connection between them is one-to-one (one I/O point to one measurement and control point of the device) so-called I/O wiring method. However, such a system has some obvious shortcomings, that is, the information integration ability is not strong; the system is not open, the integration is poor, and the professionalism is not strong; the reliability is not easy to guarantee; the maintainability is not high. If the field layer equipment is equipped with a serial data interface (such as RS-232/485), the controller can monitor the field equipment through serial communication (instead of I/O) according to the protocol specified by the interface. An electromagnetic flowmeter is an instrument that measures the flow of conductive liquids based on Faraday's law of electromagnetic induction. The application field has spread to many places such as industrial and agricultural production and scientific experiment departments, but its successful application is still limited to axisymmetric pipe flow. Non-axisymmetric flow is ubiquitous in various fields of industry. In the case of non-axisymmetric flow, there are still many theoretical and practical problems to be solved. Using a uniform magnetic field, on the basis of the Maxwell-Minkowski equation, the expression of the average flow velocity under any flow pattern is obtained by integrating the induced potential on the measuring tube wall, which can be used to measure the average flow velocity of non-axisymmetric tube flow. Industrial boilers and industrial kilns are a new type of low-polluting industrial raw materials to alleviate the energy security problem of oil shortages. In the process of CWS production and pipeline transportation, measurement and inspection must be carried out. Due to the special physical composition of coal-water slurry, its dynamic viscosity is between 500-3000MPaS (in industrial applications, the dynamic viscosity is generally controlled at 800-1500MPaS), it is a non-Newtonian fluid, and there are problems of precipitation and abrasion of solid particles, resulting in The flow measurement of coal-water slurry is very difficult. According to the experience of CWS measurement at home and abroad, electromagnetic flowmeter is the first choice for CWS measurement. This is because there are no parts that hinder the fluid in the measuring tube of the electromagnetic flowmeter, which is suitable for measuring such high-concentration solid-liquid mixtures, and it is less affected by density and viscosity, so it has become the preferred measuring instrument. The above is the whole content of this article. You are welcome to inquire about the flowmeter selection and quotation of our factory.
