Availability: Out of stock


This part has been discontinued by the manufacturer. The L150 Murphy Level Switchgage can be used as a replacement

The Murphy Liquid Level Swichgage without Fitting L150-LF instrument is a combination liquid level gauge 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. The L150 features a field adjustable set point. The unit can be mounted away from the engine for protection from vibration and extreme heat. The set point can be adjusted at any time.

The primary use of L150-LF is for engine cooling systems, surge or expansion tanks, condenser radiator or vapor phase systems, pressurized or atmospheric systems. The 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].
