PPH storage tank knowledge points: working principle of magnetic flap level gauge (magnetic float level gauge)

Working principle: Developed by buoyancy principle and magnetic coupling effect.

Scope of application: The high-temperature magnetic flap level gauge is suitable for measurement in high-temperature and high-pressure liquids, and the maximum temperature of the liquid level medium can reach 450 degrees. It is widely used in petrochemical, food, environmental metallurgy and other industries. Since the medium is completely sealed in the level gauge, it is very suitable for flammable, explosive, toxic and corrosive liquids.

Restrictions on use: The measuring medium has no or few impurities; it is not viscous and does not crystallize.

Accuracy grade: The accuracy is between ±5.0mm and ±10mm.

Advantages:
1. The measuring channel is a smooth straight pipe and will not be blocked. It is suitable for measuring liquid-solid two-phase liquids containing solid particles, such as pulp, mud, sewage, etc.;
2. No pressure loss caused by flow detection, energy saving Good effect;
3. The measured volume flow is actually not affected by changes in liquid density, viscosity, temperature, pressure and conductivity;
4. Large flow range and wide caliber range; quick and intuitive readings; low price ; Can realize remote transmission and adjustment; small size, easy to realize remote transmission and adjustment; suitable for corrosive and high-pressure media.

Disadvantages:
The accuracy is low, the measurement accuracy is generally between ±5.0mm-±10mm; the installation is complicated; there is a certain range limit; it cannot measure gas, steam and liquid with large bubbles; it cannot be used for higher temperatures; a lot of magnetic flips The plate liquid meter is inconvenient to transport and has a large installation volume.
