What activates a local alarm in a liquid ring compressor system?

In a liquid ring compressor system, a local alarm is activated when the liquid design level exceeds its specified parameters. This is crucial because maintaining the correct level of liquid in the system ensures efficient operation and protects the equipment. When the liquid level is too high, it can lead to hydraulic issues or even damage to the compressor by causing backflow or excessive pressure.

This alarm serves as a warning sign for operators to take corrective measures before potential system failures occur. The importance of maintaining the right liquid level cannot be overstated, as improper levels can significantly disrupt the compressor's performance and safety.

Humidity, low pressure readings, and airflow reduction are important operational factors, but they do not specifically trigger a local alarm in this context. Instead, they may indicate other types of system concerns that need monitoring but do not directly relate to the liquid level control or alarm systems.
