Xylem engages in the design, manufacture, and servicing of engineered products and solutions for the water and wastewater applications across global markets. was incorporated in 2011 and is headquartered in Washington, District of Columbia. Choose the method that aligns with your maintenance and data collection requirements.ģ01 Water Street SE,Suite 200, Washington, United States of America Options may include 4-20 mA DC current analog transmission, HART communication, or other proprietary communication methods. Communication Methodĭetermine the communication method for the electromagnetic flow meter. Materials like SUS316L are commonly used for general applications, while other materials like hastelloy, tantalum, or platinum iridium may be suitable for specific corrosive fluids. Select electrode and grounding ring materials that are compatible with the fluid being measured to prevent corrosion. Note that ceramic measuring tubes are typically compatible only with wafer connections.Īdditionally, choose the bore size of the measuring tube to match the connecting piping. Select the appropriate piping connection method, such as wafer or flange, based on ease of installation and removal. Options typically include rubber and PFA lining materials. Measuring TubeĬhoose the measuring tube material that matches the type of liquid to be measured. Select between a detector/transducer integrated type or a separate type based on the installation location. The choice of an electromagnetic flow meter depends on the properties of the fluid to be measured and the installation conditions. How to Select Electromagnetic Flow Meters This voltage can be used to determine the liquid flow rate. When a magnetic field is created perpendicular to the measuring tube, the conductive liquid flowing through the tube intersects the magnetic field perpendicularly, resulting in the generation of a voltage perpendicular to both the measuring tube and the magnetic field. Electromagnetic flow meters convert this voltage into flow rate data by detecting it.Ī typical electromagnetic flowmeter consists of a measuring tube through which the liquid flows, an exciting coil that generates a magnetic field, and a circuit that measures the voltage induced by electromagnetic induction. This phenomenon occurs when a conductive object moves within a magnetic field, generating a voltage proportional to its speed. Principles of Electromagnetic Flow MetersĮlectromagnetic flow meters operate based on Faraday's Law of Electromagnetic Induction, which involves the generation of voltage in a conductor moving through a magnetic field. Pharmaceuticals and blood plasma in the medical industryĪs mentioned, electromagnetic flowmeters are versatile instruments used across a wide range of fields.Beverages like fruit juice and wine in the food industry.Pulp liquids and bleaching agents in the paper industry.Basic liquids such as caustic soda used in scrubbers.Acidic liquids, including sulfuric acid and hydrochloric acid, in chemical plants.High-viscosity fluids like cement milk and mortar.Fluids containing solids, such as sand-water mixtures in civil engineering projects.Applications of Electromagnetic Flow MetersĮlectromagnetic flow meters find applications in various industries due to their ability to measure flow rates in challenging conditions. They are also capable of measuring the flow rates of slurries and corrosive chemicals containing suspended particles. When used with conductive liquids, these meters offer precise measurements unaffected by factors such as temperature, pressure, liquid density, viscosity, or conductivity. However, due to their operating principle, electromagnetic flow meters are limited to measuring conductive liquids and cannot measure insulating fluids like oils or gases. (Flow speed > 1m/s) ☐.5% F.S.Electromagnetic flow meter is a device that utilizes the principles of electromagnetic induction to measure fluid flow rates.Įlectromagnetic flow meters are characterized by the absence of moving parts and the absence of pressure drop in the measurement process.
