Electromagnetic flowmeter has a wide range of applications in various industries, such as petroleum, chemical, etc., for the choice of electromagnetic flowmeter (Xuanze), in fact, the most important thing is the choice of its lining, lining how to choose that is to understand it first, in order to help you choose the lining:

1, ordinary rubber, natural rubber, soft rubber, hard rubber.

Operating temperature of 60℃, its characteristics is elastic and has a good wear resistance.Generally used in urban water supply and drainage and other fields, corrosion resistance is relatively poor.

2, polytetrafluoroethylene (, also called PTFE, also called F4.In addition to measuring the volume flow of general conductive liquid, electromagnetic flowmeter can also be used to measure the volume flow of strong corrosive liquid such as strong acid and strong alkali and uniform liquid-solid two-phase suspended liquid such as mud, pulp, paper pulp.Widely used in petroleum, chemical, metallurgy, textile, paper, environmental protection, food and other industrial departments and municipal management, water conservancy construction, river dredging and other fields of flow measurement.

More commonly used lining material, because of its chemical stability (interpretation: stable stability;There is no change), so it is generally used for sanitary liquid or strong corrosive liquid, such as strong acid and strong alkali.

3. Polyfluorinated ethylene propylene, also known as F46.

The quality of this material is similar to that of PTFE, but the wear resistance is stronger than that of PTFE. The temperature of the same medium can reach 100℃.

4, polyfluorine (ethylene, also known as FS.Electromagnetic flowmeters are designed to generate a uniform DC or AC magnetic field.Dc magnetic circuit to achieve with a permanent magnet, its advantage is simple structure, the ac magnetic field interference is small, but it is easy to make by measuring the electrolyte liquid polarization in the ducts, the positive electrode is surrounded by negative ion, negative electrode is surrounded by positive ions, the electrode polarization, and lead to increased internal resistance between two electrodes, thus seriously affect the normal work of the instrument.

Similar to F4 material quality characteristics but bear a little worse temperature, the general medium (the decisive role of the substance) temperature does not exceed 80℃, cost-effective, low cost than F4 material.

5. Neoprene is also called CR, or Neoprene.

It is characterized by good friction resistance and excellent elasticity, and is generally used in water supply and drainage, sewage treatment and other fields.Electromagnetic flowmeter has the advantages of circuit, low power consumption, wide range ratio, simple structure, small resistance loss, durability, wide use, long service life, stable work, easy installation and debugging, etc.Mainly used for flow measurement of industrial pipeline medium fluid, such as gas, liquid, steam and other media.Corrosion resistance is slightly poor, Oxygen resistance (oxidation) is its bad place.

6, Polyurethane rubber, also known as Polyurethane.

Has excellent wear resistance, but the ability to corrosion is insufficient, and the temperature shall not exceed 80℃, generally used for wear

Seek relatively high mining environment, such as coal pulp and other media measurement.

7, ceramic (raw material: non-metallic minerals) material

Ceramics (raw material: non-metallic minerals) is undoubtedly one of the most high-end products among all materials. The disadvantage is that the price is not earthed, the production process is complex, and the technical requirements are very high, and the price is very high.The electromagnetic flowmeter in Syria to choose and buy should be according to the medium to determine the flow meter lining materials.Avoid shopping mistakes.
