Flap-11S Economical Type Magnetic Level Indicator

Flap-11S Economical Type Magnetic Level Indicator, its most prominent features are economic and practical. This indicator uses 304 stainless steel, which is particularly suitable for measuring slightly corrosive liquids. The floating tube’s diameter is 51mm/57mm, and is made of high quality 304 seamless stainless steel tube, can effectively avoid the common defects, such as leakage, low pressure, unsightly appearance, and short life, etc. Also, Flap-11S has introduced innovative production and test processes to improve its reliability and quality.

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. 

(1) Indicator panel and magnetic flaps uses widened design make visual distance and viewing angle increase greatly, the ruler and its figures are bolder and clearer.

(2) Level of Ingress Protection of IP65 and IP66/67 are available, exceeding national standard requirement of IP54;

(3) Accessory magnetic switches and remote transmitters have got double certifications of Explosion Proof and Intrinsically Safety.

(4) Made of 304 seamless stainless steel tubes, which is cost-effective.
(5) Used to monitor the level of a variety of storage tank of industrial equipment.

● Applied in hydrogenated tail gas condensate receiver tank and liquid alkali evaporator of hydrogen peroxide devices in chlor-alkali Industry.

● Used to measure the level of water tank at electrolysis plant. 

● Used to monitor the level of a variety of storage tank of industrial equipment.
