Series L6 FLOTECT Liquid Level Switch

Brand: Dwyer Instruments, LLC

Free Shipping on Orders Over $500.00 CAD

Surprisingly compact, the Series L6 Flotect® Level Switch is designed and built for years of trouble-free service in a wide variety of process liquid level applications.

Operation is simple and dependable with no mechanical linkage as the level switch is magnetically actuated.

The float lever pivoted within the body moves when the process liquid displaces the float. A magnet on the opposite end of the float lever controls a second magnet on the switch actuating lever located in the switch housing.
Features
  • Compact design is built for years of trouble-free service
  • Simple and dependable operation with no mechanical linkage
  • Float lever pivoted within the body moves when the process liquid displaces the float and magnet on the opposite end of the float lever controls a second magnet on the switch actuating lever located in the switch housing
  • Leak proof lower body machined from bar stock
  • Side wall or direct tee mounting options available to act as an external float chamber
  • Weatherproof and explosion-proof body for demanding outdoor applications
  • Electrical assembly can be easily replaced without removing the unit from the installation so that the process does not have to be shut down
  • Sensitive to level changes of less than 1/2" (12 mm)
