Definition of electromagnetic flowmeter

　　Electromagnetic flow meters (EMF) are a new type of flow measurement instrument that operates based on Faraday's law of electromagnetic induction. It is mainly used to measure the volumetric flow rate of conductive liquids, that is, the volume of liquid passing through the cross-section of a pipeline per unit time. The structure of an electromagnetic flowmeter mainly consists of a magnetic circuit system, a measuring conduit, electrodes, and an adjustment conversion device. The measurement principle is that when a conductive fluid flows perpendicular to the direction of the magnetic induction line in a magnetic field, an induced potential is generated on the electrodes on both sides of the flow pipeline. The magnitude of the induced potential is related to the fluid velocity, and the fluid flow rate can be obtained by measuring this potential.

　　The main application scenarios of electromagnetic flowmeter

　　Electromagnetic flow meters are widely used in multiple fields due to their unique measurement principles and structural characteristics, including but not limited to the following aspects:

　　Chemical industry:

　　Electromagnetic flow meters play an important role in chemical production and can be used to measure the flow rate of various acid-base salt solutions, organic solvents, gas-liquid mixtures, and other media. These media are usually corrosive or conductive, and electromagnetic flow meters can accurately measure them without being affected by changes in the characteristics of the media.

　　Water treatment industry:

　　Electromagnetic flow meters can be used to measure the flow rate of media such as water, sewage, and sludge in applications such as water supply and sewage treatment. Its measurement results are independent of the temperature, viscosity, density, pressure, and liquid-solid composition ratio of the fluid, making it particularly suitable for water treatment systems that require continuous and accurate flow measurement.

　　Food and Beverage Industry:

　　In the process of food processing and beverage production, electromagnetic flow meters can be used to measure the flow rate of various food raw materials, semi-finished products, and finished products. For example, it can be used to measure the ratio and filling situation of beverages, ensuring the accuracy and stability of the production process.

　　Pharmaceutical industry:

　　In the pharmaceutical industry, electromagnetic flow meters can be used to measure solution flow rate, ultrapure water flow rate, etc. during the pharmaceutical process. Its high precision and stability are of great significance for ensuring drug quality and production process control.

　　Other industrial sectors:

　　Electromagnetic flow meters are also widely used in industrial fields such as textiles, printing and dyeing, papermaking, chemical fibers, sugar production, steel, petrochemicals, and oil fields to measure the flow rate of various conductive liquids.

　　Explosion proof occasions:

　　Explosion proof electromagnetic flow meters are used in places with flammable atmospheres, such as specific areas in industries such as petroleum and chemical. These flow meters are usually designed as explosion-proof, sand filled, sealed, and airtight types to ensure safe use in hazardous environments.

　　Places with high hygiene requirements:

　　Sanitary electromagnetic flow meters are suitable for industrial fields such as cheese, food, medicine, and biochemistry. These flow meters require timed steam sterilization, easy disassembly and cleaning of sensors, and non-toxic and harmless materials in contact with liquids.

　　Diving and diving resistant occasions:

　　Submersible electromagnetic flowmeter is used to measure the water flow rate of open channels or non full pipe underground channels flowing naturally under the free surface, such as industrial drainage and sewage. The submersible electromagnetic flowmeter is applied in underground manholes and other places, and can withstand short-term or long-term water infiltration.

　　In summary, electromagnetic flowmeters play an important role in various fields such as industrial production, water treatment, food and beverage, and medicine due to their wide range of applications and unique measurement advantages. With the continuous advancement of technology and the expansion of applications, the performance and applicability of electromagnetic flowmeters will also be continuously improved and perfected.
