In the market, there are many different electromagnetic flow meter manufacturers, and choosing a suitable supplier becomes difficult. Electromagnetic flow meter is a commonly used flow measurement instrument, which is widely used in industrial production, water supply system, petrochemical and other fields. With the improvement of industrial automation level, users have put forward higher requirements for the performance, stability and adaptability of instrumentation. Electromagnetic flowmeter has become the preferred flow measurement tool for many industries because of its high precision, no moving parts, wide range of advantages. Selection of professional electromagnetic flowmeter manufacturers, become the key to ensure the suitability of conditions and measurement stability.
Electromagnetic Flowmeter Measurement Principle
Electromagnetic flowmeter based on Faraday electromagnetic induction principle for flow measurement. Conductive liquid moving in the magnetic field, will be perpendicular to the flow direction and magnetic field direction of the electrode between the induced voltage. The voltage signal is proportional to the flow rate of the liquid, which is detected by the sensor and transmitted to the converter, which can display the instantaneous flow rate and cumulative flow rate after signal processing.
Note: Only for conductive liquids. For the conductivity of less than 20 μS/cm media (such as pure water, oil, gas, steam, etc.), electromagnetic flowmeter can not be normal measurement.
According to the working principle of electromagnetic flowmeter, the fluid that can be used for electromagnetic flowmeter to measure the flow must be electrically conductive. Strictly speaking, in addition to high-temperature fluids, any conductivity greater than 20us/cm of the fluid can use the corresponding electromagnetic flowmeter for flow measurement, because non-conductive gases, vapors, oils, acetone and other substances can not be used electromagnetic flowmeter for flow measurement.
In industrial automation applications, different caliber electromagnetic flowmeter plays a key role in all kinds of scenarios: large caliber flowmeter Commonly used in urban water supply, industrial drainage and other large-scale delivery systems, especially in water supply and drainage projects with a wide range of applications. They can efficiently and stably measure the large flow of liquid, suitable for large pipe diameter transportation conditions. Medium and small diameter flowmeter Suitable for higher process requirements or media more complex occasions, especially for containing solid-liquid mixtures of fluids. Typical applications include: strong corrosive media flow control in the chemical industry; paper industry in the pulp, black liquor measurement; iron and steel plant blast furnace cooling water real-time control and leakage monitoring; small diameter and small caliber flowmeter is mostly found in the cleanliness, sanitation level of the industry has high requirements, such as food processing, pharmaceutical production, biological engineering. These applications usually require instruments with CIP / SIP cleaning capabilities, in line with hygiene standards, with high accuracy and low flow rate measurement capabilities.
Electromagnetic flowmeter lining materials are mainly rubber lining and PTFE lining, rubber lining is mainly suitable for wear-resistant media, rubber lining is mainly neoprene rubber and polyurethane rubber, polyurethane rubber is suitable for strong abrasive media, PTFE lining is mainly suitable for corrosion-resistant media, PTFE substrate is mainly polytetrafluoroethylene and polyperfluoroethylene propylene, polytetrafluoroethylene propylene material is suitable for strong abrasive The PTFE propylene material is suitable for strong abrasive medium. Electrode materials are mainly divided into molybdenum-containing stainless steel, Hastelloy B, Hastelloy C, titanium-tantalum, stainless steel carbide and so on.
Selecting Electromagnetic Flow Meter Manufacturers
- Product quality and accuracy
Accuracy and stability: The core of the flow meter lies in its measurement accuracy and stability. Choose those products that adopt advanced technology, have high precision and good stability.
Material Selection: Pay attention to the material selection of the flow meter, such as stainless steel, aluminum alloy, etc. These materials have an important impact on the durability, corrosion resistance and cost of the product.
- Technical strength and R&D capability
R&D team: examine whether the manufacturer has a professional R&D team, as well as the background and experience of the team members.
Technological innovation: to understand the manufacturer in the field of flowmeter technical innovation capabilities and achievements, such as whether the manufacturer has independent intellectual property rights of patented technologies.
- Production capacity and scale
Production scale: assess the manufacturer’s production scale, including the number of production lines, the degree of equipment sophistication and annual production capacity.
Delivery capacity: Understand the delivery cycle and capacity of the manufacturer to ensure that it can meet your procurement needs and on-time delivery.
- Market reputation and brand credibility
User evaluation: By checking user evaluations, case sharing and other means, we can understand the evaluation of manufacturers by other users. These evaluations can intuitively reflect the manufacturer’s product quality, service level and market reputation.
Brand awareness: choose brands with high reputation and good market recognition, these brands usually have a better service system and more reliable product quality.
- After-sales service and support
Technical support: find out whether the manufacturer provides comprehensive technical support, including product selection, installation and commissioning, troubleshooting and so on. Good technical support can ensure that the problems you encounter in the process of use can be resolved in a timely manner.
After-sales service system: assess whether the manufacturer’s after-sales service system is perfect, including after-sales service response time, maintenance service scope, spare parts supply. Quality after-sales service can reduce your cost of use and enhance the service life of the equipment.
To summarize, when choosing electromagnetic flow meter manufacturers, you should consider product quality, technical strength, production capacity, market reputation and after-sales service and other aspects. By comparing the advantages and disadvantages of different manufacturers, you can choose the one that best suits your needs.
