To determine fluid specific gravity,
add 0.1 to float specific gravity in clean
liquids and 0.3 to float specific gravity
in dirty or viscous liquids.
The LV-10 Series level switches
feature a small float displacement,
especially suited for narrow or
restricted areas. A standard 1⁄8 MNPT
fitting allows for quick installation in
either the top or bottom of the tank
or vessel. A sealed SPST switch
provides consistently high accuracy
and repeatability while minimizing
the effects of shock, vacuum, or
vibration. Extremely versatile, the
switch is user selectable as normally
open or normally closed by simply
removing the retaining clip and
inverting the position of the float.
For intermediate float displacement,
the LV-20 Series will yield long life
and greater stability for a broad
range of level monitoring
requirements. The LV-30 Series
larger float displacement is intended
for use with liquids of high viscosity,
and is well suited for harsh
environments. Both models share
the standard features of the LV-10.
