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
