Flap-11S
Economical Magnetic Level Indicator is practical and economical. It is made of 304 stainless steel
and suitable for mild corrosive liquids. The chamber with 51mm diameter is made of high quality 304
seamless stainless-steel tube. It effectively avoids the common problems with
conventional stainless-steel tube, such as leakage, insufficient pressure
endurance, poor appearance and short life time, etc. Besides, Jiwei has
developed innovative technologies, introduced full production process
management and test to improve the reliability also quality of Flap-11S.
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.
● 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.
● Made of 304
seamless stainless-steel tubes, economical and practical.
