  • L150/EL150K1: Level Swichgage for Engine Liquids

    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.
