FW Murphy L150/EL150 Liquid Level Switchgage

The L150 Series Level Swichgage® instrument is a combination liquid level gage 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.
