Wire type: 2‐conductor
Wire length: 2’ (61 cm)
Mounting threads: 1/8" NPT
Classification:
General purpose, CE
Installation:
1. Switches should be installed rigidly so the float or
floats are free to move as the liquid level
changes.
2. Switches should be mounted in a tank area free
of severe turbulence or protected from such
turbulence by appropriate and adequate slosh
shields.
3. Vertical switch stems should be vertical for best
results, but satisfactory operation is possible in
most liquids with the stem at up to a 20° angle
from vertical.
4. Care should be taken that switches are always
operated within electrical ratings.
5. Orientation for switches can be changed from
normally open to normally closed dry or vice
versa by removing the float and reversing it in the
stem.

Top Wall Installation: Omega Engineering LV‐510 series switch may be installed through the top wall of a
tank. Because the thread of the sensor is very small (1/8”), finding standard fittings may be difficult. In lieu of
standard fittings, one suggestion is to use a larger pipe, such as ½”. Place a cap or plug on the end of the pipe
and tap a 1/8” thread into the end. Secure the other end of the pipe to the top of the tank or to a clamp. For
pipes longer than 2’, be sure to cleanly extend the cable (splice) so that the connection is not exposed to the
liquid.
