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].
