Anti-corrosion electromagnetic flowmeter principle and product features

Anti-corrosion electromagnetic flow meters are mainly used to measure the volume flow of water, sewage, pulp, mud, various acids, alkalis, salt solutions, food slurries and other slurries and conductive liquids in closed pipelines. They are used in petroleum, chemical industry, metallurgy, It is widely used in pharmaceutical, food, textile, papermaking and other industries as well as environmental protection, water conservancy construction, municipal management and other fields

It uses recent technology to overcome the problems caused by the sine wave magnetic field. shortcomings, but also 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 enables the anti-corrosion electromagnetic flowmeter to have the advantages of the rectangular wave magnetic field. At the same time, it also eliminates the errors caused by power supply voltage fluctuations, power supply frequency changes and excitation coil impedance changes. plays an important role in other aspects. The measurement principles summarized on the basis of Faraday's law of electromagnetic induction are also equivalent.

Anti-corrosion electromagnetic flowmeter has many product features. The outstanding product feature is that there are no flow-impeding parts in the measuring tube, there is no pressure loss, and the requirements for straight pipe sections are relatively low. This is also one of the important reasons for the popularity of this product. Secondly, the measurement is relatively stable and is less affected by changes in the external environment, especially not affected by changes in fluid density, pressure, viscosity, temperature and conductivity. Furthermore, the converter adopts a novel excitation method, and the converter can be integrated or separated from the sensor, with low power consumption, high height, and stable zero point.

The flow range can reach 1500:1. At the same time, the converter also uses surface mounting technology SMT, which has self-check and self-diagnosis functions, making it safer and more reliable to use. The converter uses a 16-bit high-performance microcontroller. Processor, 2x16LCD display, set convenient parameters to make programming reliable. The flow meter is a bidirectional measurement system, equipped with three totalizers for forward total volume, reverse total volume, and difference total volume. It can display forward and reverse flow rates, and has multiple outputs such as pulse, digital communication, and current. There are various choices of rear sensor lining and electrode materials to meet the needs of most people!

The principle of the anti-corrosion electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. The product has distinctive features and is a good instrument for measuring the volumetric flow rate of conductive liquids and slurries in closed pipelines!
