Description

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

The L150 Series Level Swichgage instrument is a combination liquid level gage and low-limit switch; each unit includes a chamber with pivotal float, an indicating dial with pointer and 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 is for engine cooling systems, surge or expansion tanks, condenser radiator or vapor phase systems, pressurized or atmospheric systems. The Level Swichgage instrument 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].
