Electromagnetic flowmeter measures alkaline solutions containing solid particles

　　1、 The working principle of electromagnetic flowmeter

　　Electromagnetic flowmeter is an instrument that uses Faraday's law of electromagnetic induction to measure the flow rate of liquid in conductive pipelines. It ionizes the liquid inside the conductive pipeline through electromagnetic force, forming induced electromotive force, and calculates the flow rate of the liquid according to Faraday's law of electromagnetic induction. Conventional electromagnetic flow meters are suitable for liquid media with low viscosity and good conductivity. However, in actual production, liquid media often contain various impurities such as solid particles, bubbles, pollutants, etc., which can affect the measurement accuracy of electromagnetic flow meters.

　　2、 The advantages of electromagnetic flowmeter in measuring alkaline solutions containing solid particles

　　Electromagnetic flow meters have the following advantages in measuring alkaline solutions containing solid particles:

　　1. Accurate measurement of high flow rate: Because the sensor of the electromagnetic flowmeter is in the shape of a straw and does not pass through a pipeline, it can adapt to high flow rate environments, making the measurement more accurate and avoiding measurement deviation caused by solid particles getting stuck in the sensor.

　　2. Not affected by solid particles: The flow sensor of the electromagnetic flowmeter has no mechanical components and has almost frictionless characteristics, so it will not be damaged by the presence of solid particles, resulting in inaccurate measurement or inability to work.

　　3. Accurate measurement of liquid flow rate: The accuracy of electromagnetic flowmeter can reach ± 0.5%, which can meet the requirements of production control for flow measurement.

　　3、 Precautions for measuring alkaline solutions containing solid particles using electromagnetic flow meters

　　Although electromagnetic flowmeters have certain advantages in measuring alkaline solutions containing solid particles, the following precautions should also be taken during use:

　　1. Do not install the electromagnetic flowmeter on pipelines containing impurities such as bubbles and solid particles, as this may affect the measurement accuracy of the electromagnetic flowmeter.

　　During the selection process, it is necessary to choose a suitable electromagnetic flowmeter based on the actual working conditions, and install, debug, and operate it according to the requirements in the electromagnetic flowmeter product manual.

　　4、 Conclusion

　　In summary, electromagnetic flowmeters are capable of measuring alkaline solutions containing solid particles with high accuracy and are not affected by solid particles. By implementing precautions, their measurement accuracy can be better ensured.
