PRODUCT INTRODUCTION
D2 CDU Coolant Monitor for Liquid Cooling
The D2 CDU Coolant Monitor is a clamp-on ultrasonic flowmeter designed for non-intrusive monitoring of coolant flow in liquid-cooled data center environments. It supports common coolants like deionized water, glycol mixtures, and fluorocarbon fluids. By attaching externally to stainless steel pipes (DN15–DN32), it measures flow velocity and cooling load without disrupting pipe integrity, making it ideal for dense server rack setups. Real-time data via RS485 and 4–20 mA output enables integration with CDU (Coolant Distribution Units) to dynamically balance cooling across racks, prevent hotspots, and optimize energy efficiency.
