Introducing the L1200 model Level Switch, specially crafted for gas compressor scrubber level applications. It excels in low-pressure scenarios, making it ideal for non-pressurized vessel level switching. Electric models are commonly deployed for high-level shutdowns in engines or electric motors, while pneumatic models efficiently operate vessel dump valves like the Murphy DV-series. Originally designed for gas compressor scrubber level, low-pressure models have found utility in various applications such as fuel, lube oil, hydraulic oil, and more.

Please note that the Murphy Series 1200 Liquid Level Switches are currently undergoing an upgrade, with the enhanced and more robust design of the Murphy LS200 Series Liquid Level Switches. The SLS (Scrubber Level System), comprising the high level switch, pneumatic level switch, and DVU Dump valve, is exclusively available with the LS200 Series Switches, providing an improved solution for your liquid level sensing needs.
