Designed primarily for gas compressor scrubber level. Low pressure models can be used anywhere level switching of a non-pressurized vessel is required. Electric models are typically used for high level shutdown of the engine or electric motor, while pneumatic models operate vessel dump valves such as Murphy DV-series. Models designed for low level switching have been used for fuel, lube oil, hydraulic oil, etc.

The Murphy Series 1200 Liquid Level Switches are being replaced with the improved, more robust design of the Murphy LS200 Series Liquid Level Switches. The SLS (Scrubber Level System) which includes the high level switch, pneumatic level switch and DVU Dump valve will only be offered with the LS200 Series Switches, now available.
