IntroductionFlange electromagnetic flowmeter is a flowmeter that tests flow based on Faraday’s law of electromagnetic induction. Flange electromagnetic flowmeter has been used worldwide for more than half a century. The advantages of flange electromagnetic flowmeter are extremely small pressure loss and a large measurable flow range. The ratio of maximum flow to minimum flow is generally above 10:1. The applicable industrial pipe diameter range is wide, up to 3m. The output signal and the measured flow are linear, with high accuracy. It can measure the flow of acid, alkali salt solution, water, sewage, corrosive liquid, mud, ore pulp, pulp and other fluids with conductivity ≥5μs/cm. AdvantagesAdvantages and Disadvantages of Flange Electromagnetic Flowmeter:The main advantage of flange electromagnetic flowmeter is that it has no moving parts, no pressure loss, and extremely low maintenance cost.The flange electromagnetic flowmeter has a wide range of calibers, from DN15 to DN3000mm, and can measure flow in both directions. The electromagnetic flowmeter has built-in self-diagnosis function, supports data logging/Bluetooth function and multiple output signals. Compared with other liquid flowmeters, the limitation of flange electromagnetic flowmeter is that it can only be used for conductive liquids. For non-conductive or low-conductive liquids, such as petroleum products, organic solvents, it cannot be used. If there is a strong magnetic field in the surrounding environment, the flange electromagnetic flowmeter will be affected. Application Flange electromagnetic flowmeter installation requirements：Flange electromagnetic flowmeters are widely used in process flow measurement and control of industrial and agricultural production enterprises such as iron and steel metallurgy, water supply and drainage, Water conservancy and irrigation, water treatment, sewage treatment stations (environmental sewage control, chemical sewage, electroplating sewage), paper mills (pulp), mud, petrochemicals, medicine, food, etc.In the iron and steel metallurgical industry, it is often used for cooling water flow control of continuous casting steel, continuous rolling…

Project Background： In order to improve the efficiency of water resource utilization and effectively narrow the gap between production and sales, a tap water company recently organized and implemented a regional metering project for urban water supply networks. The project divided the water supply network into regional management by installing regional electromagnetic flow meters and other equipment on the water supply pipelines. Project Analysis： Water supply zone metering is to install flow meters in the water supply network to form relatively independent areas, and actively control leakage by measuring and analyzing the amount of water entering or flowing out of the area. After the implementation of water supply zone metering, the urban water supply network will be able to accurately control leakage, reduce the leakage rate of the water supply network, and avoid the waste of water resources caused by leakage. It can not only achieve the overall goal of saving urban water resources, but also improve the level of water supply management and ensure the safety of urban water supply. The transformation of household water meters is the basic work of water supply zone metering. Its core is to realize the intelligent transformation of user water meters, realize accurate metering through remote data transmission, and grasp the user’s water use situation in real time. Once leakage and other problems are found, they can be dealt with in the first time to reduce user losses.   In this regional metering project, Flowmeterexpert provided electromagnetic flowmeters and installed them on site to help the water company control leakage and accurately measure. The construction and application of regional metering systems will help improve the management level of pipeline leakage management, instrument standard management, smart water operation management, etc., while improving the optimization operation level of the pipeline network and improving economic and…
