Choice of Float Materials
A versatile range of vertical float level switches
available as top or side mount. These switches are
used extensively throughout most industries, and
offer switching options from single point through
to multipoint systems. The flexibility of this product
makes it a single solution for alarm and/or control
requirements with high, low and intermediate
levels available on the single device, making this
an ideal product for storage tanks, pits, sumps and
day tanks.
Floats are selected based on the density of the
fluid and material compatibility and contain a
permanent magnet which activates a hermetically
sealed reed switch within the stem. Float travel is
restricted by carefully placed float stops to ensure
positive switch activation and accurate level
detection.
Materials in contact with the liquid and vapours in
the process include Stainless Steel or Polyophylene
Methylene (POM) floats, Stainless Steel stems and
Typical applications are high and/or low alarm and
process connections and aluminium terminal
pump control. Materials in contact with the liquid
enclosure allowing the FLS to be compatible
