Jiwei Flap-11 Magnetic Level Indicator Passed SIL2 / SIL3 Functional Safety Assessment

Recently, Jiwei Flap-11 Magnetic Level Indicator series has successfully passed the SIL2 / SIL3 Functional Safety Assessment authorized by Instrumentation Technology and Economy Institute (ITEI).

Flap-11 Magnetic Level Indicator can be equipped with Reed-11 Remote Transmitter and SW-11 magnetic switch to fulfill remote level control with SC3 systematic secure integrity and SIL2/SIL3 hardware secure integrity protection. This indicates the quality of Jiwei Flap-11 Magnetic Level Indicators have reached international safety standard and the highest instrumental safety standard in petrochemical production.

Currently, Jiwei has applied for 7 patents (both invention patents and utility patents) on Flap-11 series products.

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; the innovative 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 also available for Flap-11 Magnetic Level Indicator series product: 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. Furthermore, distinctive design with broader display panel and magnetic flaps greatly increases both visual distance and viewing angle. With larger sharp scale and digits, display panel appears beautiful and elegant outlook. Based on those innovative design, Jiwei magnetic gauges make level visible from up to 200 feet away.

Above characteristics and advantages of the Flap-11 fully meet the requirements of SIL2/SIL3 Functional Safety Assessment. All along, Jiwei has been offering customers with the most cost-effective made-in-China level measuring instruments with high reliability comparable to international famous brand products, as well as providing professional and optimal level measuring solutions.
