Flap-11C Plastic Magnetic Level Indicator

The chamber is made of PP/PVC, suitable for level measurements of low pressure and corrosive liquid. It has been typically applied as follow:

 Level measurement for regeneration tank, refrigerant tank, hydrochloric acid tank, alkali tank in sulfate removal system with membrane method for depleted brine treatment at a caustic soda plant.

 Level measurement for wastewater tank at a sewage treatment plant.

 Level measurement for raw material tanks at a dyeing plant.

  • 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 model Flap-11A, which greatly facilitates the installation. Also, we have developed innovative manufacturing technology and introduced full production process management and test to improve the reliability of the product. Flap-11C is particularly suitable for chemical water treatment and wastewater treatment at a 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 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 iquid 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 isindicated. 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.

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

     Made of high quality material PP, stronger corrosion resistance.

     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, IP65 and IP66/IP67 are available for different applications.

     Accessory magnetic switches and remote transmitters have been explosion protection certified for both Flameproof Enclosure and Intrinsically Safety.
