 1、 Overview: ARSLDE intelligent electromagnetic flowmeter is a fully intelligent flowmeter developed by our company using the latest advanced technology at home and abroad. It has significant differences from old-fashioned analog or non intelligent electromagnetic flowmeters, especially in terms of measurement accuracy, reliability, stability, functionality, and service life. Intelligent electromagnetic flowmeter is a high-precision, high reliability, and long service life flow instrument. Therefore, we pay great attention to every aspect of the product structure design, material selection, process formulation, production assembly, and factory testing process. We have also independently designed the most advanced production equipment and flow calibration device for electromagnetic flowmeters in China, which can effectively ensure the long-term high quality of the product in both software and hardware. The ARSLDE intelligent electromagnetic flowmeter is specially designed with a backlit wide temperature Chinese LCD display, which is fully functional, practical, intuitive, and easy to operate, reducing the inconvenience caused by other electromagnetic flowmeter English menus. In addition, we exclusively design 4-6 multi electrode structures to further ensure measurement accuracy and eliminate the need for grounding rings at all times, reducing the size of the instrument and the hassle of installation and maintenance. 2、 Characteristics: The measurement of flow rate is not affected by changes in fluid density, viscosity, temperature, pressure, and conductivity. The sensor induced voltage signal is linearly related to the average flow rate, resulting in high measurement accuracy. ★ There is no obstruction in the measuring pipeline, so there is no additional pressure loss; There are no movable parts inside the measuring pipeline, so the sensor has an extremely long lifespan. Due to the fact that the induced voltage signal is formed in the entire space filled with a magnetic field and is the average value on the surface of the pipeline, the straight pipe section required for the sensor is relatively short, with a length of5Double the diameter of the pipeline. The sensor part only has the inner lining and electrodes in contact with the measured liquid. As long as the electrode and inner lining materials are selected reasonably, they can be corrosion-resistant and wear-resistant. The ARSLDE converter adopts the latest and most advanced international microcontroller (MCU) and surface mount technology (SMT), with reliable performance, high accuracy, low power consumption, stable zero point, and convenient parameter setting. Click on the Chinese display LCD to show accumulated flow, instantaneous flow, flow rate, flow percentage, etc. ★ Bidirectional measurement system, capable of measuring forward and reverse flow rates. Using special production processes and high-quality materials to ensure stable product performance over a long period of time. ARSLDE intelligent electromagnetic flowmeter is suitable for measuring the volumetric flow rate of conductive liquids and slurries in closed pipelines, such as clean water, sewage, various acid-base salt solutions, mud, slurry, pulp, and liquids related to food. 3、 Measurement principle The measurement principle of ARSLDE intelligent electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. When a conductive liquid cuts magnetic field lines in a magnetic field, an induced potential is generated in the conductor, and the induced potential E is: E=KBVD In the formula: K - instrument constant B -- Magnetic induction intensity V - Measure the average flow velocity within the cross-section of the pipeline D - Measure the inner diameter of the pipeline cross-section When measuring flow rate, the conductive liquid moves at a velocity of V The flow of conductive liquid through a magnetic field perpendicular to the direction of flow induces a voltage proportional to the average flow velocity. The induced voltage signal is detected by two or more electrodes in direct contact with the liquid and sent to a converter through a cable for intelligent processing. Then, it is displayed on an LCD or converted into a standard signal of 4-20mA and 01kHz output. 4、 How to choose the right type The selection of instruments is a very important task in instrument applications. Relevant data shows that 2/3 of instrument failures in practical applications are caused by incorrect selection or installation of instruments. Please pay special attention. 5collect data ① Composition of the tested fluid ② Maximum flow rate, minimum flow rate ③ Maximum work pressure ④ Maximum temperature, minimum temperature The range Q of the intelligent electromagnetic flowmeter should be greater than the expected maximum flow value, while the normal flow value should be slightly greater than 50% of the flowmeter's full-scale scale. VIThe maximum and minimum flow rates must comply with the numbers in the following table
