Displacer Level Switch

HGFL-1200 series displacer level switch is designed and manufactured to meet high temperature and high pressure operation demands. It is designed to meet ANSIB31.1 standard.

Due to rational structure design and enhanced reliability, the displacer type level switch can sensor liquid level accurately even under bad working conditions and then perform switch action. It can be used as a control and alarm system for various liquid containers and supports working with high temperature and high pressure mediums.

This range of displacer level switch is often found in industries such as petroleum, chemical, power generation, food processing, pharmaceutical, and more.

Design Advantages
The liquid level sensor is designed with multiple installation methods and structures, so as to accommodate the different connection formats of equipment sets in petroleum and chemical engineering industries.

It is your optimum choice if you are looking for superior quality liquid level switches for industrial liquid level measurement and control purposes.
