Magnetic Level Indicator 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. Jiwei Flap-11 Magnetic Level Indicator series products possess features and strength of similar products in the market. Based on that, Jiwei has carried out extensive study on common problems of existing products in the market, and developed innovative techniques in design and production process to overcome the problems. Jiwei has been focusing on details of manufacturing technologies, strict control of production flow and quality inspection to ensure all products reach the highest level possible on quality and reliability. Jiwei has applied for 7 patents (both invention patents and utility patents) on Flap-11series products, of which 5 have been authorized and 2 are under approval. For Flap-11 series products, front protective cover is made of glass panel or acrylic sheet; the end fittings and glass sealing process for indicator are unique designed; the Ingress Protection rating exceeds national standard IP54 and higher level IP65 or IP66/IP67 are achieved, and can be selectable for various applications; the innovative designed magnetic coupling system between floats and flaps greatly improves the reliability of magnetic coupling system and avoids some flaps being mistakenly flipped then causing false reading. F4 (PTFE)/F46 (FEP) lined chamber is available for Flap-11 Magnetic Level Indicator series product. It is manufactured in special developed lining technologies with multiple patents. F4 (PTFE) lined chamber meets the requirements of majority level measurement applications for strong corrosive liquids with poor permeability and F46 (FEP)lined chamber is suitable for strong corrosive liquids with good permeability, such as liquid chlorine or bromine water. www.jiweiauto.com Shenzhen Jiwei Automations Ltd.
