Series F6 & F7 Level Switch - Horizontal/Specialty

Brand: Dwyer Instruments, LLC

The Series F6 & F7 Horizontal Float Level Switches are designed to mount through the walls of tanks and other vessels.

Internally mounted models F6-HPS-11, F6-MHS and F7-SS6 are secured to the wall of the tank or vessel from the inside while model F6-HPS-21 is mounted from the outside (externally).

Models F7-HSS and F6-MHS2 can be installed internally or externally. 

The SERIES F6 & F7 Specialty Float Level Switches are designed for unique applications.

Model F7-SS5B/BNC can be used with viscous liquids or liquids with suspended metal particles.

Use model F7-LL for low level detection (≥ 5/8"). The non-intrusive bottle style F7-EB mounts completely outside the tank at the actuation level.

Suspend model F7-WBB in stand pipes or sumps for leak detection or drop into wells for ground-water monitoring.
Features
  • Hermetically sealed reed switches are actuated by magnets permanently bonded inside the float arm and can be easily adapted to open or close a circuit on rising or falling levels.
