FW Murphy Liquid Level Switch EL150EX. The EL150EX Liquid Level Switch® instrument is an explosion-proof combination liquid level gauge and low level switch.The instrument includes: (1) a chamber with a rotating float, (2) a dial with pointer, and (3) a low level contact.When properly installed and maintained, the float operates the pointer which in turn both indicates the level during normal operation and closes a switching circuit when the level drops to the low limit set point.
