Flap-11C Plastic Magnetic Level Indicator

 Lightweight and easy to install, only about 1/5 weight of similar product that made of stainless steel.

 Made of high-quality PP material, stronger corrosion resistance.

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

 Exceeds national Ingress Protection standard IP54, Ingress Protection rating IP65 and IP66/67 are selectable for different applications.

 Magnetic switch and remote transmitter have all passed SIL2 / SIL3 Functional Safety Assessment, as well as certified for both Intrinsic Safety and Flameproof Enclosure explosion protection.

  • Flap-11C Plastic Magnetic Level Indicator is a commonly used corrosion resistant level meter. With the same measuring range, its weight is only about 1/5 of the standard type of Flap-11A, which greatly facilitates the installation. Also, Jiwei has developed innovative technologies, introduced full production process management and test for Flap-11C to improve the reliability and quality. Flap-11C is particularly suitable for chemical water treatment and wastewater treatment at power plant, printing and dyeing industry, as well as other acidic mediums which are not miscible with PP.


  • Flap-11 Magnetic Level Indicator series products are designed based on the law of equilibrium in U connected vessels and magnetic coupling effect to achieve real-time level measurements and display. As liquid level in the vessel varies up or down, magnetic float in the connected chamber rises or falls simultaneously. Because of magnetic coupling effect, float with a permanent magnet actuates magnetic interacted flaps in the display panel which is mounted beside chamber. Associated flaps will flip 180 degree to indicate liquid level. The front and back surface of flaps are coated with two colors respectively (red and white). Generally, when liquid level rises, the magnetic float moves up and makes associated magnetic flaps flip from white to red, and when liquid level drops, associated magnetic flaps flip from red to white. The interface between red and white flaps is the actual indicated liquid level inside the vessel. According to different chemical properties of measured medium, appropriate materials should be selected carefully for the chamber and the magnetic float. In addition, the weight, volume and structure of magnetic float have to be taken into consideration according to different density of measured liquid in order to achieve optimal measuring accuracy.
