How the Scrubber Level Control System (SLS) Works

The Scrubber Level Control System (SLS) continuously monitors liquid levels inside a gas scrubber or separator vessel using a mechanical float mechanism. As liquid accumulates within the vessel, the float rises in response to the changing level.

When the liquid reaches the preset operating range, the system activates the pneumatic dump valve, allowing controlled discharge of accumulated liquid while maintaining stable operating conditions inside the vessel.

If liquid levels exceed safe thresholds, the integrated high-level shutdown switch provides a protective signal to prevent compressor damage or operational hazards. This dual-level control approach ensures both continuous regulation and safety protection in high-pressure environments.
