Changzhou Chengfeng Instrument Co., Ltd. is a company integrating R&D, production, and sales. It has a history of more than 30 years. The intelligent electromagnetic flowmeter is developed based on the standard manufacturing system. Its advanced design concept ensures the high precision and high reliability of the product. Compared with the old electromagnetic flowmeter, it has high measurement accuracy, reliability, and stability. Good, functional, long life and other advantages.
Electromagnetic flowmeter has a wide range of applications in various industries, such as petroleum, chemical, etc. For the selection of electromagnetic flowmeter, the most important thing is the choice of its inner liner. How to choose the inner liner should be understood firstly. To help everyone make the liner selection:
1, ordinary rubber.
The medium temperature is 60°C, which is characterized by its elasticity and good wear resistance. Generally used in urban areas such as water supply and drainage, corrosion resistance is relatively poor.
2, PTFE, also known as PTFE, also known as F4.
One of the more commonly used liner materials, because of its chemical stability, it is generally used for sanitary liquids or highly corrosive liquids, such as concentrated acid and concentrated alkali.
3, polyfluorinated ethylene propylene, also known as F46.
This material is similar to PTFE, but its wear resistance is stronger than that of PTFE. The same medium temperature can reach 100°C.
4, polyurethane rubber.
Has excellent wear resistance, but for the corrosive performance is inadequate, and the temperature must not exceed 80 °C, generally used for high wear resistance requirements of the mining environment, such as pulp slurry and other media measurements.
5, ceramic material
Ceramics is undoubtedly the best of all materials, absolutely high-end products, the only drawback is that the price is not grounded gas, the production process is complex, the process requirements are extremely high, and the price is high.
Therefore, when selecting the lining material of the electromagnetic flowmeter, the user should consider the nature of the measured medium, such as temperature, chemical properties, etc., and then consider the economy of the price, and choose according to their own actual conditions, in order to play the best role. .
