Combination of electromagnetic flow meter and ultrasonic flow meter

Abstract: The information on the combination of electromagnetic flowmeters and ultrasonic flowmeters is provided by excellent flowmeter and flowmeter manufacturers. In the fields of petroleum, chemical industry, water resources, etc. that use the most flowmeters, the most common ones are ultrasonic flowmeters and electromagnetic flowmeters. Why are these two kinds of meters the first choice and widely used? Let's analyze their main advantages. 1. Application. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the details of the combination of electromagnetic flowmeters and ultrasonic flowmeters. In the fields of petroleum, chemical industry, water resources, etc. that use the most flowmeters, the most common ones are ultrasonic flowmeters and electromagnetic flowmeters. Why are these two kinds of meters the first choice and widely used? Let's analyze their main advantages. 1. Wide application range. Electromagnetic flowmeters can measure various acid-base liquids, sewage, pulp and other conductive media, and non-conductive ultrapure water, pure water, reclaimed water and other non-conductive liquid media can be measured by ultrasonic flowmeters, so these two instruments are mutually Combined, almost all common liquids can be measured. 2. High measurement accuracy. In terms of flow measurement, it can be said that the higher the accuracy, the better. These two instruments perform very well in terms of accuracy. The conventional accuracy is 1.0, the slightly higher requirement reaches 0.5, and the highest accuracy can reach 0.3 or even 0.2. The performance in the instrumentation is very good. 3. There is no pressure loss in the non-blocking components. Whether it is an electromagnetic flowmeter or an ultrasonic flowmeter, there are almost no parts inside the guide tube, so there will be no obstruction to the medium and no pressure loss. However, the electromagnetic flowmeter will be limited by some ultra-high pressure occasions. At this time, the external clamp ultrasonic flowmeter can be used, and the pressure will not have any effect on the flow measurement. 4. Easy to install. Generally speaking, the flow measurement on the industrial site is connected with flanges. If it is inconvenient to damage the existing pipeline, it can be installed with external clamps, which is very convenient. 5. Cost-effective. In addition to requiring ultra-high precision, the prices of these two instruments are relatively affordable and acceptable to the public. Of course, these two instruments are not all advantages, and some shortcomings will also limit their use in more fields and a wider range, such as the performance of both instruments under ultra-high temperature. We look forward to breakthroughs in new materials and technologies to make them even better. Errors caused by various reasons in the application of electromagnetic flowmeters, such as fluid conductivity, fluid composition, and dirt on the inner wall of electromagnetic flowmeters. The electromagnetic flowmeter works according to the principle of Faraday's law of electromagnetic induction. When a conductor with electrical conductivity cuts magnetic lines of force in a magnetic field, an induced electromotive force will be generated upstream and downstream, and the direction is in accordance with the right-hand rule. Therefore, in the application of general electromagnetic flowmeters, there are certain requirements for the conductivity of the fluid, and 5us/cm is used as the dividing line during the application process. Electromagnetic flowmeters and ultrasonic flowmeters are all velocity flowmeters, and all the factors that affect their accuracy include: the flocculation of the fluid (whether the fluid is evenly distributed), and the scale in the lining. 1. Error caused by flocculation of fluid: When the flow velocity V of the liquid in the pipeline is axisymmetric distribution, and in a uniform magnetic field, the magnitude of the electromotive force generated on the electrode of the flowmeter has nothing to do with the flow velocity distribution of the fluid, and is related to the average flow velocity of the fluid. Otherwise, the induced electromotive force generated by the counter electrode will be different. Therefore, the electromagnetic flowmeter must be installed in the measuring pipe section with the smallest possible fluid flow turbulence to avoid unnecessary errors. 2. Errors caused by the inner scale of the lining: In chemical enterprises, water treatment enterprises, and measuring instruments for daily life water, we often see a layer of scale or chemical pollution attached to the inner wall. Don't underestimate this thin layer. It can change the electromotive force deviation of the electromagnetic flowmeter, and then generate the zero point dislocation. Therefore, we often see some sewage treatment plants. In order to improve their measurement accuracy, they often clean the electrodes inserted into the electromagnetic flowmeter. At present, electromagnetic flowmeters still play a dominant role in the fluid measurement, energy-saving detection and other industries. With the improvement of electronic chip technology and computer computing efficiency, they are gradually being replaced by ultrasonic flowmeters. The above is the whole content of this article.
