 Flanged Top External Caged Liquid Level Switches   Printer Friendly Version
Flanged external cage type level switches are completely self-contained units designed for side mounting to a tank or vessel with threaded, socket weld or flanged pipe connections. In hundreds of industrial applications throughout the petroleum refining, petrochemical production and power generation markets, these switches have demonstrated their worth through reliable and repeatable service.

The buoyancy force of a process liquid on the float causes the float to ride on the liquid surface. The movement of the float with the liquid level moves an attraction sleeve into the field of the switch magnet, pulling the magnet toward the sleeve and actuating the switch.
