Electromagnetic flowmeter is an instrument that measures the volumetric flow rate of conductive liquids based on the working principle of Faraday’s law of electromagnetic induction. It is a product of the combination of fluid mechanics and electromagnetics. When a conductor cuts magnetic field lines in a magnetic field, it generates induced electromotive force at both ends. An electromagnetic flowmeter consists of two parts: a sensor and a converter. It is an inductive instrument used to measure the volumetric flow rate of conductive liquids with a conductivity greater than 5 μ S/cm. In addition to measuring the volumetric flow rate of general conductive liquids, it can also be used to measure the volumetric flow rate of strong corrosive liquids such as strong acids and alkalis, as well as homogeneous liquid-solid two-phase suspensions such as mud, slurry, and pulp. By using high-quality and reliable components and optimizing the structure, the magnetic field can be optimized and distributed more evenly. At the same time, the zinc spraying process has been introduced, which can effectively protect the surface of the electromagnetic flowmeter even in harsh environments, with superior surface anti-corrosion performance. Widely used in industrial sectors such as petroleum, chemical, metallurgical, textile, papermaking, environmental protection, food, as well as municipal management, water conservancy construction, river dredging and other fields for flow measurement.

Precautions for electromagnetic flowmeter

1. The accuracy level and function of the instrument are selected based on measurement requirements and usage scenarios to achieve cost-effectiveness. For example, in situations such as trade settlement, product handover, and energy measurement, higher accuracy levels such as 1.0, 0.5, or higher should be selected; For process control applications, choose different accuracy levels according to control requirements; In some cases where only the process flow rate needs to be detected without precise control and measurement, a slightly lower accuracy level, such as 1.5, 2.5, or even 4.0, can be selected. In this case, a low-cost plug-in electromagnetic flowmeter can be used.
2. When measuring medium flow rate, instrument range, and caliber, the full flow rate of an electromagnetic flowmeter can be selected within the range of 0.5-12m/s for measuring medium flow rate, which is relatively wide. The selection of instrument specifications (caliber) may not necessarily be the same as the process pipeline, and should be determined based on whether the measured flow range is within the flow rate range. That is, when the pipeline flow rate is too low to meet the requirements of the flow instrument or the measurement accuracy cannot be guaranteed at this flow rate, the instrument port diameter needs to be reduced to increase the flow rate inside the pipeline and obtain satisfactory measurement results.
3. Try to avoid ferromagnetic objects and equipment with strong electromagnetic fields as much as possible to prevent the magnetic field from affecting the working magnetic field and flow signal of the sensor.
4. It should be installed in a dry and ventilated place as much as possible, avoiding direct sunlight and rain. The ambient temperature should be between -20 and+60 ℃, and the relative humidity should be less than 85%.
5. There should be ample space around the flowmeter for easy detection and maintenance.

Application scenarios of electromagnetic flowmeter

Electromagnetic flowmeter is a flow measurement instrument based on the principle of electromagnetic induction, mainly used to measure the instantaneous flow rate and cumulative flow rate of conductive liquids. It has a wide range of applications and involves industrial production process control in multiple fields. The following are the main application scenarios of electromagnetic flow meters:

1. Water treatment industry: In the process of water supply, drainage, and sewage treatment, it is necessary to accurately measure the flow rate of water to ensure the stability of the process and cost control. Electromagnetic flow meters can be applied for water quantity measurement in these scenarios.
2. Chemical and pharmaceutical industries: Accurate flow detection and control of various corrosive liquids are required in the production of chemical drugs or pharmaceuticals. Due to the low electrical performance requirements of the medium, electromagnetic flowmeters are suitable for such environments.
3. Food processing industry: Many aspects of the food processing process involve fluid control and monitoring, such as the fluid conveying system in beverage production lines. Electromagnetic flow meters can be used to ensure the stability of product quality and improve production efficiency.
4. Power industry: Electromagnetic flow meters are commonly used for monitoring and managing reservoir discharge in hydroelectric power plants or other hydroelectric power stations. In addition, it can also be used as a flow indicator for cooling water and boiler feedwater.
5. Other application areas: This also includes flow detection and calculation of liquid raw materials or semi-finished products in industries such as papermaking and metallurgy. In short, due to its high precision, reliability, and good adaptability, electromagnetic flowmeters have become an indispensable component in the field of industrial automation.
