Description
The L150 Series Level SWICHGAGE®is a combination liquid
level gauge and low limit switch; each unit includes (1) a chamber
with pivotal float, (2) an indicating dial with pointer, and (3) a low
level contact. When properly installed and maintained, the float
operates the pointer which, in turn, both indicates level during nor-
mal operation, and closes a switching circuit if the level falls to the
low-limit set point.
Applications
The primary use of the L150/EL150K1 is for engine cooling sys-
tems, surge or expansion tanks, condenser radiator or vapor
phase systems, pressurized or atmospheric systems. The Level
SWICHGAGE®can also be used to monitor lube oil, hydraulic
fluid or diesel fuel reservoirs and activates alarms and/or shut-
down at a predetermined minimum level.
These instruments are built for low pressure systems with a
maximum of 25 psi (172 kPa) [1.72 bar].
