Non-Conductive Coolants: Why Ultrasonic Flowmeters Are the Inevitable Choice

When the power consumption of a single AI training chip exceeds 1000 W and the heat density of a GPU server rack surpasses 100 kW, traditional air cooling — with a heat transfer coefficient only 1/25 that of liquid — is no longer an option but a bottleneck. Liquid cooling has rapidly shifted from an “optional solution” to a “mandatory solution.” However, liquid cooling is not a single technology. A fundamental choice lies at the root of every liquid cooling architecture: Must the coolant be conductive? The answer determines system architecture, safety boundaries, and maintenance logic — and ultimately decides which flow measurement technology should be used.
