    L150, EL150K1, EL150EX Level SWICHGAGE® series For Engine Liquids

    The L150 series Level SWICHGAGE® is a combination liquid level gauge 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.

    Model L150 has a single electrical connection (contact grounds on low fluid level). Model EL150K1 has a snap-switch (SPDT contacts with insulated wiring).


    • Fluid level monitoring for coolant, oil, diesel fuel and hydraulic fluid.
    • Gauge face and pointer indicates fluid level
    • Float operated low level switch, triggers alarm or shutdown protection
    • Float adjustment knob for operator test of alarm or shutdown
    • Optional explosion-proof model EL150EX
