L4 Level switch operates automatically
to indicate tank level. Perfect for starting or stopping pumps, opening or
closing valves, or actuate level alarm signals. A unique magnetically
actuated switching design gives superior performance. There are no
bellows, springs, or seals to fail. Instead, the free-swinging float attracts
a magnet within the solid metal switch body, actuating a snap switch by
means of a simple lever arm. Float arm hinge design limits the arm angle
to prevent vertical hangup.

• Leak proof body machined from bar stock
• Choice of floats dependent on maximum pressure and specific gravity
• Weatherproof, designed to meet NEMA 4
• Explosion-proof (listings included in specifications)
• Installs directly and easily into tank with a thredolet or flange
(see application drawings on page 4)
• Electrical assembly can be easily replaced without removing the unit
from the installation so that the process does not have to be shut down
• Horizontal installation or optional top mount vertical installation
!!% $
• Direct pump control for maintaining level
• Automatic tank dump operations
• Control levels or provide alarms in sumps, scrubber systems, hydro-
pneumatic tanks, low pressure boilers, and various waste
water/sewage treatment processes
