Ring-11 and Flap-21 Applied to LIER-Chemical Group

As the world’s second and China largest producer of chlorinated pyridine herbicides and pesticide, the subsidiary of LIER-Chemical Group -- Sichuan Montreal Crop Science recently purchased Jiwei’s flame-proof Liquid Level Switch and Magnetic Level Indicator as their main level measurement equipment. The company applied Ring-11 and Flap-21 to the pipe of pump protection system and the level measurement of pesticide storage tank.

According to the detection principle of solid and liquid, Jiwei’s Tuning Fork Switches divide into two types – level switch and liquid level switch. Ring-11 Liquid Level Switch detects vibration frequency change of the fork body when fork body is immersed in medium. Thus, it is suitable to use in foams, air bubbles, viscous liquid and conditions with complex vibrating interference. Also, Ring-11 specializes in liquid level measurement and it is designed with only 40 mm length of the fork body.
