Measuring flow in liquid-cooled data center racks is critical as power densities increase and traditional air cooling falls short. This comprehensive guide explains how coolant flow is monitored in direct-to-chip and rear-door heat exchanger systems, including equations, sensor technology tradeoffs, and BMS integration. It is written for engineers responsible for designing and operating modern, high-density data centers.

Learn about the different types of temperature data loggers used across industries such as food, pharmaceuticals, HVAC, and manufacturing. Compare thermocouple, RTD, thermistor, and wireless models to choose the right logger for your monitoring needs.

High-density data centers are rapidly adopting liquid cooling technologies such as direct-to-chip cold plates and rear-door heat exchangers to manage racks drawing 15–30 kW or more. These systems often rely on propylene glycol mixtures in primary and secondary loops to transport heat safely and efficiently. However, introducing liquid to IT spaces introduces leak risk. Effective leak detection, integrated with a building management system (BMS) and tuned for water-glycol mixture, is now critical for uptime. Using IOThrifty solutions such as the LD1 Leak Detection System and LD Leak Detection Switch, engineers can deploy wide-area sensing, pinpoint leak location, and trigger immediate alarms to protect servers and maintain cooling continuity.
