Anti-corrosion electromagnetic flowmeter principle and product features introduction

Anti-corrosion electromagnetic flowmeter is mainly used to measure the volume flow of water, sewage, pulp, mud, various acid, alkali, salt solution, food slurry and other slurry and conductive liquid in closed pipeline, in petroleum, chemical, metallurgy, pharmaceutical, food , textile, paper and other industries as well as environmental protection, water conservancy construction, municipal management and other fields are widely used.

It adopts the latest technology in the world, which overcomes the shortcomings of sinusoidal magnetic field and has the advantages of high stability and high reliability. The use of constant current low-frequency three-value rectangular wave and dual-frequency rectangular wave excitation makes the anti-corrosion electromagnetic flowmeter have the advantages of rectangular wave magnetic field, and also the error caused by power supply voltage fluctuation elimination, power supply frequency variation and excitation coil impedance variation. Other aspects have an important role. The measurement principle summarized on the basis of Faraday's law of electromagnetic induction is also quite accurate.

Anti-corrosion electromagnetic flowmeter has many product features. The most prominent product feature is the measurement of unobstructed flow components in the tube, no pressure loss, and relatively low straight pipe requirements, which is one of the important reasons for the popularity of the product. Secondly, it is more stable when measured and less subject to changes in the external environment, especially from changes in fluid density, pressure, viscosity, temperature and conductivity. Furthermore, the converter adopts a novel excitation mode, and the converter can be integrated or separated from the sensor, and has low power consumption, high precision, and stable zero point.

The flow range is up to 1500:1. At the same time, the converter also uses surface mount technology SMT. It has self-test and self-diagnosis functions. It is safer and more reliable to use. The converter adopts 16-bit high-performance microprocessor, 2x16LCD display. Convenient parameters are set to make the programming reliable and accurate. The flowmeter is a two-way measuring system with three totalizers: positive total, reverse total and total difference. It can display positive and negative flow, and has various outputs such as pulse, digital communication and current. Finally, the sensor lining and electrode materials are available in a variety of ways to meet the needs of most people!

The principle of anti-corrosion electromagnetic flowmeter draws on Faraday's law of electromagnetic induction, and its product features are distinctive. It is a good instrument for measuring the volume flow in conductive liquid and slurry in closed pipeline!
