The Mejor electromagnetic flowmeter is meticulously designed based on Faraday's law of electromagnetic induction, specifically designed for precise measurement of the volumetric flow rate of conductive liquids and slurries in closed pipelines. Its core structure includes key components such as measuring tubes, electrodes, excitation coils, iron cores, and magnetic yoke shells.
In practical operation, the conductive medium inside the measuring tube is like a conductive metal rod in Faraday's experiment, with a constant magnetic field generated by electromagnetic coils at the upper and lower ends. Once a conductive medium flows through, a voltage will be induced, which is measured by two electrodes inside the pipeline. At the same time, the measuring pipeline utilizes non-conductive lining to achieve electromagnetic isolation from the fluid and measuring electrodes, ensuring measurement accuracy.
This electromagnetic flowmeter has significant advantages. Firstly, the measurement process is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity, ensuring the stability of the measurement results. Secondly, there are no components obstructing the flow inside the measuring tube, almost no pressure loss, and low requirements for the straight pipe section, which can effectively reduce installation costs and space requirements. Thirdly, by selecting sensor lining and electrode materials reasonably, it can have excellent corrosion resistance and wear resistance, suitable for measuring highly corrosive liquids such as acids, alkalis, salts, etc., and can be used in industries such as chemical and metallurgical industries. Fourthly, the converter adopts a novel excitation method with low power consumption, stable zero point, high accuracy, and a flow range of up to 150:1, which can meet diverse flow measurement needs. In addition, the converter can be flexibly integrated or separated from the sensor to adapt to different installation environments and usage scenarios; It also uses a 16 bit high-performance microprocessor, paired with a 2x16 LCD display screen, with convenient parameter settings and reliable programming; The flowmeter has bidirectional measurement function and is equipped with three integrators: forward total, reverse total, and difference total. It can clearly display forward and reverse flow rates and supports multiple output methods such as current, pulse, digital communication, and HART; It uses surface mount technology (SMT) and has self checking and self diagnostic functions, which facilitates equipment maintenance and troubleshooting.
In terms of structural form, Mejor electromagnetic flowmeter offers various options such as integrated, split, immersed, explosion-proof, etc; The protection level covers IP65 IP67,IP68, Flexible selection can be made based on the protection requirements of different application scenarios. It is widely used in many industries such as petroleum, chemical, metallurgical, textile, food, pharmaceutical, papermaking, as well as in fields such as environmental protection, municipal management, and water conservancy construction. It is a powerful assistant for achieving accurate flow measurement and efficient production control.
