Flowmeters for liquid cooling systems are specific application of flow measurement. Their main advantages include good accuracy
at low flow rates (regardless of viscosity) as well as small size and cost savings.
Benefits
-Minimized dimensions and weight
-Large viscosity range: up to 300 cSt
-Very low flow measured: from few litres per hour (<10 pph)
-Simplicity and reliability: a single moving element
-Low pressure drop
-Continuous flow even if the rotor is blocked
-No power source required
-Easy and cost-effective maintenance
-Fixed K-factor (LRU)
-Calibration with equivalent fluid
