LS200 & L1100 Series Liquid Level Switches
LS200NDVOR
is a float-activated, pneumatic-vent level
device used to operate dump valves or similar devices.
The LS200NDVOR provides a 2" NPT mounting with a
pneumatic output for interfacing with pneumatic devices such
as our Murphy pneumatic dump valve or with other pneumatic
instrumentation.
LS200NDVO
is the Dump Valve Operator (DVO) without the
pressure regulator for those applications where the system
provides a filter regulator for "instrument quality" air or gas as the control medium.
LS200N
is the pneumatic level switch without the DVO and filter regulator.
NOTE: Pneumatic media devices require clean, dry, instrument quality air or gas. This unit is
supplied with a pressure regulator, filter and Murphy 20BPG pressure gage for improved
system life and trouble-free operation.

• Electric and pneumatic models available
• More robust design
• All models screw directly into the vessel or can be mounted via external float chamber

LS200
Liquid Level Switches with 2" NPT mounting are float
activated to operate an electrical SPDT snap switch (optional
DPDT on some models) for alarm or shutdown of an engine or
electric motor. The LS200 connects directly into the vessel wall
and can be used with a Murphy weld collar (P/N 15050375) or
Murphy external float chamber (P/N 15700799). L1100
models (1-1/2" NPT) are also available.
