Electromagnetic flowmeter is widely used in petroleum, chemical, metallurgy, textile, food, pharmaceutical, papermaking and other industries as well as environmental protection, municipal management, water conservancy construction and other fields. Electromagnetic flowmeter fabric material (or directly with the media touch measuring tube) is mainly rubber and Teflon, ceramics, F46 four, and it touches the fluid sensor components have a fabric (or measurement made of insulating material) Tube), electrodes, grounding rings and gaskets, the corrosion resistance of the material, wear resistance and the upper limit of the application temperature affect the appearance of the adaptability of the fluid. Because of the small number of parts, the simple shape, and the sensitive material selection, the magnetic flowmeter sensor has strong adaptability to fluids.
Electromagnetic flowmeter urethane rubber has excellent wear resistance, but acid and alkali corrosion is poor. Its abrasion resistance is equivalent to 10 times that of natural rubber, and is suitable for coal slurry, pulp, etc.; medium temperature is lower than 40 ~ 60/70 °C. The earliest application of fluoroplastics is PTFE, which can only be used for negative pressure piping because of the pressure and adhesive force between the measuring tube and the negative pressure piping. Afterwards, various modified types are developed, injection molding is completed, and the measuring tube is Strong binding force can be used for negative pressure, neoprene and fiberglass, but also for non-corrosive or weakly corrosive liquids, such as industrial water, waste water and weak acid and alkali, the lowest price.
Electromagnetic flowmeter fluorine plastic has excellent chemical resistance, but poor wear resistance, can not be used to measure the slurry.
Alumina ceramics have excellent wear resistance and abrasion resistance to strong acids and bases. The wear resistance is about 10 times that of polyurethane rubber. It is suitable for corrosive slurries. However, brittleness is easy when the device is clamped. Crushed, can be used for higher temperatures (120 ~ 140/180 °C) but to prevent drastic changes in temperature, such as steam sterilization, usually the temperature change can not be greater than 100 °C, 150 °C heating time for 10 minutes.

Electromagnetic Flowmeter
In drying process, heat medium, such as steam, hot water or thermal oil, is connected to the drying shelf which transfers heat to wet material. Under vacuum condition, boiling point of moisture is much lower. So the moisture can be evaporated under low temperature. The vacuum pump constantly sucks out the evaporated moisture to speed the drying process. Vacuum pump, tubular condenser and buffer tank are equipped to recover the evaporated moisture.
