Research on flow meter in sewage flow measurement

Abstract: The research information of flow meter in sewage flow measurement is provided by excellent flow meter and flow meter manufacturers. Abstract: The environmental protection industry has higher and higher requirements on the accuracy and reliability of sewage flow measurement and control. This article introduces the selection and design of several types of flowmeters such as electromagnetic, vortex, and throttle flowmeters. Combined with water treatment Craft, from both theoretical and practical aspects. For more flowmeter manufacturers to select models and price quotations, you are welcome to inquire. The following is the details of the research article on flowmeters in sewage flow measurement. The environmental protection industry has higher and higher requirements for the accuracy and reliability of the measurement and control of sewage flow. The characteristics of each are expounded from both theoretical and practical aspects. Subject words: flowmeter measurement of sewage selection, a foreign flow expert F.C.Kinghoro once said that flowmeter is one of the few types of viscous friction that is more difficult to use than to manufacture, and also produces unstable vortex and secondary flow and other complex flow phenomena . The measuring instrument itself is affected by many factors, such as: pipeline, diameter size, shape (circle, rectangle), boundary conditions, physical properties of the medium (temperature, pressure, density, viscosity, dirt, corrosiveness, etc.), fluid flow state (turbulent flow state, velocity distribution, etc.) and the influence of installation conditions and levels. In the face of more than a dozen types and hundreds of varieties of flow meters at home and abroad (the types of volumetric, differential pressure, turbine, area, electromagnetic, ultrasonic and thermal flowmeters developed successively), how to Reasonable selection of factors such as flow state, installation requirements, environmental conditions, and economy is the premise and basis for the application of flow meters. In addition to ensuring the quality of the instrument itself, it is also very important to provide process data and whether the installation, use and maintenance of the instrument are reasonable. This paper introduces the selection and design of several types of flowmeters such as electromagnetic, vortex, and throttle. 1. Electromagnetic flowmeter selection and design Since the first industrial application in China in the late 1950s, electromagnetic flowmeters have been used and developed rapidly in flow measurement in the 1970s and 1980s. The working principle of electromagnetic flowmeter is based on Faraday's law of electromagnetic induction, that is, the measured medium flows perpendicular to the direction of the magnetic field lines, so an induced electromotive force EX is generated in the direction perpendicular to both the medium flow and the magnetic field lines. ), the electromagnetic flowmeter is not affected by external factors such as temperature, pressure, viscosity, and gravity, and there is no shrinkage or pressure loss in the protruding part inside the measuring tube. In addition, the initial signal detected by the flow element is an average of the fluid. The flow rate is a voltage that changes accurately and linearly, which is independent of other properties of the fluid and has great advantages. According to the characteristics of sewage with large flow changes, impurities, low corrosiveness, and certain electrical conductivity, electromagnetic flowmeters are a good choice for measuring the flow of sewage. It has compact structure, small volume, convenient installation, operation and maintenance. For example, the measuring system adopts intelligent design and the overall sealing is strengthened, so that it can work normally in harsh environments. The electromagnetic flowmeter with neoprene lining and molybdenum-containing stainless steel (OCrI8Ni12Mo2Ti) electrode can be selected to meet the requirements of sewage flow measurement. During the production of a smelter, a large amount of industrial sewage will be generated due to the needs of the production process, and the sewage treatment plant must monitor the flow of sewage. In the previous design, many flow meters used vortex flowmeters and orifice flowmeters. In practical application, it is found that the deviation between the measured flow display value and the actual flow is large, and the deviation of the electromagnetic flowmeter is greatly reduced. 2. Vortex flowmeter selection and design As a new type of flowmeter, vortex flowmeter has developed rapidly since the mid-1980s. It has many advantages and advantages in flow measurement, and is more and more widely used in modern flow measurement. . The use of vortex flowmeters for flow measurement in my country has also been paid more and more attention. At present, there are product series with excellent performance and independent intellectual property rights in China.
