Intelligent electromagnetic flowmeter

With the development of the times, more and more products tend to be intelligent. At present, China is slowly moving from an agricultural country to industry. Therefore, the amount of industrial instrumentation is increasing, and it is becoming more and more intelligent. Especially the electromagnetic flowmeter. Because electromagnetic flowmeters have a wide range of applications and are not subject to external interference, they are used in many industrial situations. With the development of technology, intelligent electromagnetic flowmeters are even more popular in major industrial situations, especially for sewage treatment. Someone will ask, what is an intelligent electromagnetic flowmeter? What are the advantages of an intelligent electromagnetic flowmeter compared with the previous electromagnetic flowmeter? Then the following editor will uncover the mystery for everyone.　　Principle: Electromagnetic Flowmeters (EMF for short) is a new type of flow measuring instrument that developed rapidly with the development of electronic technology in the 1950s and 1960s. Although the intelligent electromagnetic flowmeter saves time and effort compared with the previous electromagnetic flowmeter, the principle remains the same. The principle of electromagnetic induction is also used to measure the conductive fluid based on the electromotive force induced when the conductive fluid passes through an external magnetic field. An instrument of flow.　　Structure: The structure of the intelligent electromagnetic flowmeter is mainly composed of magnetic circuit system, measuring catheter, electrode, shell, lining and converter.　　Features: 1. The measurement is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity; 　　2, there are no obstructive flow parts in the measuring tube, no pressure loss, and lower requirements for straight pipe sections. It has unique adaptability to slurry measurement; 　　3, reasonable selection of sensor lining and electrode materials, that is, it has good corrosion resistance and abrasion resistance; 　　4, the converter adopts a novel excitation method, low power consumption, stable zero point, and high accuracy . The flow range can reach 150:1; 　　5, the converter can be integrated with the sensor or separated; 　　6, the converter adopts 16-bit high-performance microprocessor, 2x16LCD display, convenient parameter setting, reliable programming; 　　7, flow It is a two-way measurement system with three totalizers: forward total, reverse total and difference total; it can display positive and negative flow, and has multiple outputs: current, pulse, digital communication, HART; 8. The converter adopts surface mount technology (SMT) and has self-check and self-diagnosis functions; 　　 9. The measurement accuracy is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity, and the sensor's induced voltage signal is linear with the average flow rate Relationship, so the measurement accuracy is high.　　10. There is no obstruction in the measuring pipeline, so there is no additional pressure loss; there are no moving parts in the measuring pipeline, so the sensor has an extremely long life.　　11. Since the induced voltage signal is formed in the entire magnetic field-filled space and is the average value of the pipe surface, the straight pipe section required by the sensor is shorter, and the length is 5 times the pipe diameter.　　12. The converter adopts the latest and most advanced international single-chip microcomputer (MCU) and surface mount technology (SMT), with reliable performance, high precision, low power consumption, stable zero point, and convenient parameter setting. Click on the Chinese display LCD to display cumulative flow, instantaneous flow, flow rate, flow percentage, etc.　　13. Two-way measurement system, which can measure forward and reverse flow. Special production technology and high-quality materials are used to ensure that the performance of the product remains stable for a long time.　　 Through the principle, structure and characteristics of the intelligent electromagnetic flowmeter introduced by the editor above, we must have a general understanding of the intelligent electromagnetic flowmeter. In addition, electromagnetic flowmeters are also divided into two types according to the type of applied magnetic field, DC type and induction type. In addition, according to the different display methods, they are divided into split electromagnetic flowmeter and integrated electromagnetic flowmeter. You can choose when purchasing.
