The tuning fork liquid level switches, or liquid level switches can detect the limit liquid level point and output alarms in time to realize overfill protection and dry run protection.

Jiwei Fork-11 Tuning Fork Level Switches were successfully operated in PVDF interface level measurement. Only if VDF monomer float in the water and come into contact with the fork, an alarm signal will be issued.

Tianjin enterprise ordered 56 pieces SIL certified tuning fork liquid level switches from Jiwei for liquid level measurement in pharmaceutical production. In which, 18 pieces are with 2-metre-long extension tines.

To ensure stable production, Tuning Fork Level Switches are installed in the powder receiver to control the start-stop of pneumatic conveying system by outputting switch signals.

Tube-11 Vibrating Rod Level Switch is designed with double vibrating tubes, which prevents bulk material from getting stuck or jammed.

Ring-21 can withstand 150 ℃ high temperature and 40 bar process pressure, and has higher reliability, which fully meets the requirements of steam generator.

　　After going through a large number of tests and analysis, engineers in Jiwei found following measures could facilitate the applications of rotary paddle switch in level measurement for moisturized material.

Jiwei Ring-11 Fork Liquid Level Switches were successfully applied in the process of separation and purification (mainly extraction) for liquid level measurement in a pharmaceutical plant.
