Electromagnetic Flowmeters (Electromagnetic Flowmeters, simply known as EMF) is the 20th century 50 ~ 60 years with the development of electronic technology and the rapid development of a new type of flow measurement instrumentation, electromagnetic flowmeter is the application of the principle of electromagnetic induction, according to the conductive fluid through the applied magnetic field generated by the electromotive force to measure the flow of electrically conductive fluid flow of a kind of instruments, electromagnetic flowmeter The structure of the magnetic circuit system, measuring conduit, electrode, shell, lining and converter and other components, according to the type of installation can be divided into split, insertion type, one-piece, split electromagnetic flowmeter to meet the field display at the same time, but also can output 4 ~ 20mA current signal for recording, regulation and control, insertion type electromagnetic flowmeter is designed for the medium and large aperture measurement of the pipeline, one-piece electromagnetic Flow meter is based on Faraday's law of electromagnetic induction, used to measure the volume flow of electrically conductive fluids, due to the unique characteristics have been widely used in industry for a variety of electrically conductive liquid measurements, mainly used in the chemical industry, papermaking, food, textiles, metallurgy, environmental protection, water supply and drainage and other industries, and computers can be realized with the system control.
➭High measurement accuracy, 0.5 grade, good stability;
➭The measurement is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity;
➭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;
➭Reasonable selection of sensor lining and electrode materials can achieve good corrosion resistance and abrasion resistance;
➭Converter adopts novel excitation method, low power consumption, stable zero point and high accuracy. The flow range can reach 150:1;
➭The converter can be integrated with the sensor or separated;
➭The converter adopts 16-bit high-performance microprocessor, 2x16LCD display, convenient parameter setting and reliable programming;
➭The flowmeter 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;
➭The converter adopts surface mount technology (SMT), with self-check and self-diagnosis functions;
➭The measurement accuracy is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity. The sensor induced voltage signal has a linear relationship with the average flow rate, so the measurement accuracy is high;
➭There are no obstructions 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;
➭Because the induced voltage signal is formed in the entire space filled with magnetic field and is the average value of the pipe section, the straight pipe section required by the sensor is shorter, and the length is 5 times the pipe diameter;
➭The converter adopts the latest and most advanced single-chip microcomputer (MCU) and surface mount technology (SMT) in the world, 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.;
➭ Two-way measurement system, which can measure forward flow and reverse flow. Special production technology and high-quality materials are used to ensure the performance of the product and remain stable for a long time.
