The gas-tight leadthrough of Jiwei Ring-11 High-pressure Protection Liquid Level Switch is the glass-metal encapsulation connector that configures between process connection and meter head.

　　In order to maintain the long-term and effective usage of rolling furnace, it is significant to monitor the level, temperature and pressure of water.

All Ring-11s have been working reliably under high temperature explosive and strong corrosive severe working environments.

Jiwei Fork Liquid Level Switches and magnetic level indicators have excellent quality and are widely used in liquid level measurement for grain oil production, petrochemical industry etc.

Jiwei Rotary Paddle Switches have been running smoothly with stable and reliable performance to ensure the normal operation of the waste incineration power plant since they were installed and put into use.

　　Some time ago, a large petrochemical plant in Zhangzhou selected Jiwei Ring-11 fork liquid level switches for their white oil tanks after investigating and comparing products in the market in their procurement process. The first batch of 204 units was purchased and used to substitute for imported products in high/low oil level control for white oil tank.

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.

Jiwei Ring-11 Fork Liquid Level Switches perform well in level measurement for crude oil storage tanks. The instruments have been reliably working and never had false alarms since they were installed.

Jiwei Flap-11Px FEP lined magnetic level indicator has been installed and in stable and reliable operation for more than a year in the chemical plant in Shandong mentioned above.

Generally, materials for chamber and display panel of a magnetic level indicator are selected according to the properties of the measured medium.
