Product Introduction
The QMF clamps straight onto 10 mm tubing and, by time-of-flight ultrasound, tracks coolant down to 0.1 L/min with ±2 % FS accuracy. Its millisecond update pinpoints micro-leaks before hotspots form. It ships with barb, push-in or quick-twist fittings for plug-and-play upgrade of liquid cooling system.
