Seeries 3 ASME B31.1 – Liquid Level Switches
The Series 3 float and displacer-actuated level switches are designed, built, and certified to meet the requirements of ASME B31.1. They are ideal for critical alarm set points in clean liquid applications.
Measurement Principle :
The buoyancy force of a process liquid on the float causes the float to move with the liquid surface. The movement of the float moves an attraction sleeve into the field of the switch magnet, pulling the magnet toward the sleeve and actuating the switch.
