Series L6 FLOTECT® Liquid Level Switch

Series F6 & F7 Level Switches - Horizontal/Specialty

Low Cost, Hermetically Sealed Contacts

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-SS5BNC 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.

Questions

Question
How does the F6-HPS-11 Level Switch attach to my tank?
Answer
Drill a 1/2" hole in the side of your tank. With the F6-HPS-11 body inside the tank, insert the screw and exposed wires through this hole and secure the unit in place with the corresponding nut.
Question
Why is the minimum specific gravity important on the float level switches?
Answer
If a medium has a lower s.g. than the rated minimum for a float, the float will sink through the media and the switch will not operate.
