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 in). 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.

• Combine low cost and reliability with fast, simple installation
• Hermetically sealed reed switches are actuated by magnets permanently bonded inside the float and can be easily adapted to open or close a circuit on rising or falling levels
• Easily reverse switch action by removing the float, rotating it end-for-end and replacing it on the stem
• Vertical models mount internally, oriented within 30° of vertical, or select optional fittings for external mounting
• Switch ratings are suitable for many solid state control systems and monitors or alarms
• Simple relay interfaces can be used for higher current applications
