Flap-11Px Lined Magnetic Level Indicator

The chamber is made of 304 stainless steel lined with PTFE for strong corrosive liquid level measurement. It has been typically applied as follow:

 Level measurement for brine tanks, the caustic circulation tank, the brine de-chlorination tower, the chlorate decomposition tank, the ultra-pure hydrochloric acid storage tank in a membrane electrolysis apparatus.

 Level measurement for storage tanks for liquid chlorine or bromine water.

 Level measurement for ammonia storage tanks.

 Liquid level monitor for the monomer tank at a PVC manufacturing plant.

  • Flap-11Px Lined Magnetic Level Indicator is designed with unique lining techniques. The lining junction between the chamber and the process connecting flange is well fit to effectively avoid the lining crack due to the stress during the assembly and prevent the instrument from corrosion damage caused by the medium leakage because of the crack of the lining. We also have introduced full production process management and test For Flap-11Px to improve its reliability and quality. Three patents are applied on Flap-11Px. One invention patent (application NO.201710919511.7) is under verification and two utility patents (patent NO. 201621028672.4 and NO.201721282291.3) are authorized. Flap-11Px is mainly used for strong corrosive liquids. It is widely applied in chemical industry, oil refining, storage and transportation, water treatment, etc.


    Flap-11Px Lined Magnetic Level Indicator comes with F4 (PTFE)/F46 (FEP) lined chamber for selection. F4 (PTFE) lined chamber is suitable for majority of strong corrosive liquids with poor permeability, while F46 (FEP) lined chamber is suitable for strong corrosive liquids with good permeability, such as liquid chlorine, bromine water.
  • Flap-11 Magnetic Level Indicator series products are designed based on communicating tube and the principles of magnetic coupling function to achieve real-time level measurements. When the measured liquid’s level in the vessel changes, the magnetic float in communicating tube will go up and down, and the permanent magnet steel inside the magnetic float makes the magnetic flaps of the indicator outside the communicating tube turn by 180° which is driven by the magnetic coupling function. Usually the front and back surface of flaps are coated with two different colors respectively (normally red and white) to indicate the actual liquid level inside the vessel. When the level of vessel rises, the flaps turn from white to red, and when the level of vessel drops, the flaps turn from red to white, at the red and white junction, the actual level of vessel is indicated. According to different chemical properties of the measured medium, appropriate materials for the communicating tube should be applied. In order to achieve to the best accuracy of measurement, the magnetic float’s weight, volume and structure have to be satisfied with the density of measured liquid.

  •  With unique design and lining technology between the chamber and the process connection flange, effectively avoids the lining crack due to the stress during the assembly and prevents the instrument from corrosion damage caused by medium leakage.

     Display panel with broader design,greatly increases the visual distance and viewing angle,. With larger sharp scale and digits, the indicator appears beautiful and elegant outlook.

     Level of Ingress Protection exceeds national standard IP54, higher level protection IP65 and IP66/IP67are available for different applications.

     Provides F4/F46 lined chamber manufactured with multiple patented lining techniques, suitable for broader range of corrosive liquids level measurement.

      ● F4 (PTFE) lining can be applied for majority of strong corrosive liquids with poor permeability.

      ● F46 (FEP) lining can be applied for strong corrosive liquids with good permeability, such as liquid chlorine, bromine water.

     Magnetic switch and remote transmitters have been explosion protection certified for both Flameproof Enclosure and Intrinsically Safety.
