The EL150EX Liquid Level Swichgage® instrument is an explosion proof combination liquid level gage and low limit switch; the instrument 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 EL150EX features a fixed set point. When properly installed, the unit is mounted at your required liquid level. The set point cannot be tampered with.

The primary use of the EL150EX is for engine cooling systems, surge or expansion tanks, condenser radiator or vapor phase systems, pressurized or atmospheric systems. The EL150EX Liquid Level Swichgage® instrument 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 instrument is built for low pressure systems with a maximum of 25 psi (172 kPa) [1.72 bar].
