Float Level Switches provide low-cost solution

Float switches from AutomationDirect provide a low-cost solution for liquid level monitoring. Shock and vibration resistant, the float operates a reed switch via magnets as the liquid level moves the float. Various models offer compatibility with many liquids, temperature ranges, and system pressures.

  • Available in several material constructions for compatibility with many liquid types
  • Vertical and horizontal mounting styles offer flexible mounting with a variety of process connections
  • Operating temperature ratings up to 482°F
  • Suitable for a wide range of system pressure requirements
  • Reed switches offer both AC and DC voltage ratings
  • Most models are field configurable for N.O. or N.C. operation

Vertical float switches are mounted at the top or bottom of a tank or vessel and have a float that rises or falls along the stem. Magnets within the float actuate a hermetically sealed reed switch as the float rises and lowers with liquid level.

The FLS-VL-900 submersible liquid level switch is weighted for suspension in non-magnetic tanks and can be used in conjunction with a still pipe. Its materials are suitable for water, hydrocarbons, and certain chemicals.

The FLS-VM-800 float switch features a 3/4” PVC pipe fitting process connection and is ideal for use in HVAC condensate lines.

ProSense float level switch kits provide a convenient, field-customizable two-float level switch with a maximum stem length of 36 inches (914.4 mm). The kits are available in brass or 316 stainless steel constructions for compatibility with different liquids. Each kit contains two floats, a 2" NPT pipe plug, cuttable connecting tubes, and compression unions.

Float level tilt switches provide reliable level detection in open vessels, sumps, and ponds. These switches include a 7-meter cable, a weight, and an EPDM rubber float with a micro-switch that changes state as the float rises or falls +/- 45° from its nominal position.
