The Murphy Explosion Proof Liquid Level Swichgage Without Fittings EL150EX-LF is a combination liquid level gauge and low limit switch. 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.

The primary use of the EL150EX-LF is for engine cooling systems, surge or expansion tanks, condenser radiator or vapor phase systems, pressurized or atmospheric systems. This liquid level swichgage can also be used to monitor lube oil, hydraulic fluid or diesel fuel reservoirs and activate alarms and/or shut-down at a predetermined minimum level. This is built for low pressure systems with a maximum of 25 psi (172 kPa) [1.72 bar].
