Due to the good adaptability and high reliability in difficult conditions, Vibrating Rod Level Switches are widely favored by Shandong alumina electrolysis industry.

Jiwei Ring-11 Liquid Level Switch are with both Ex-approval and Intrinsically Safe Certification (Exia IIC T6、Exd IIC T6), is an ideal choice for chemical industry.

Tube-11 has higher reliability than other international brands’ instrument, so Fujian Zijin Mining changed all UWT level switches to Jiwei Tube-11 Vibrating Rod Level Switch.

Flap-11S Economical Magnetic Level Indicators are used by Guofeng to measure the liquid level of 31% hydrochloric acid.

Shihua Chemical Company has installed over 200 Jiwei Magnetic Level Indicators for a new ionic membrane electrolysis technology industrialization experiment project with a manufacturing capacity of 400,000 tons/year.

Hebei Shenghua Chemical Industry Co.purchased Jiwei Rada-11 Pulse Radar Level Meters and Flap-11S Economical Type Magnetic Level Indicators.

LIER-Chemical Group purchased Jiwei’s flame-proof Ring-11 Liquid Level Switches and Flap-11 Magnetic Level Indicators as their primary level measurement equipment.
