Liquid-cooling leak detection and alarm planning
Use layers of leak detection
A robust plan combines equipment signals such as pressure, flow and tank level with point sensors, sensing cable or tray detection where liquid could escape. One alarm type alone may not cover slow seepage, a connection failure and a larger pipe event equally well.
Place sensors around real failure points
Review CDU connections, manifolds, quick connectors, valve stations, hose routes, rack bases and low points. Sensor placement must consider drainage paths, containment, maintenance access and the conductivity of the actual coolant.
Define alarm actions before commissioning
For every alarm define who is notified, required verification, pump or valve action, server response, event logging and restart authority. Test the alarm chain during commissioning and record periodic test intervals.

Common questions
Is a sensing cable enough for liquid cooling?
Not always. Combine location detection with CDU process signals and project-specific logic.
Will every sensor detect glycol coolant?
No. Check the detection principle and sensitivity against the actual coolant.
Should an alarm stop the CDU automatically?
That depends on risk, redundancy and server requirements. Validate the cause-and-effect sequence for the project.
Final configuration, performance, applicable requirements and delivery are defined in the agreed project specification.
