• Monitors Level of Coolant, Lube Oil, Diesel Fuel And Hydraulic Fluid.
• Indicating Gauge
• Low Limit Switch

• Explosion-Proof Model Is Available.

EL150EX Models are CSA Listed for Class I, Division 1, Group C & D Hazardous Locations.

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 normal 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 systems, 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].
