F6-F7

Low cost, reliable, and compact vertical or horizontal float level switches for liquids. SPST Hermetically sealed reed switch, reversible for normally open or normally closed action.

See model selection chart below.

Dwyer F6 and F7 vertical float level switches can be mounted at the maximum or minimum level point for level indication and control. Models are shipped with normally open switch contacts which close as the float rises toward the mounting threads. You can reverse the switch action by removing the float, rotating it end-to-end, and replacing it on the stem.

Typical applications include water level monitoring, tank level control, oil level control, chemical level indication, sumps, stand pipes, and high viscosity liquids.

  • Low cost, reliable, simple installation
  • Hermetically sealed reed magnetically actuated switches can be easily adapted to open or close a circuit on rising or falling levels
  • Easily reversable switch action
  • Switch ratings are suitable for many solid state control systems and monitors or alarms
  • Simple relay interfaces can be used for higher current applications
