WebEssentially, mass flow rate is the amount of mass of a gas or liquid that flows in a certain amount of time, for instance expressed in kilograms per hour (kg/h) or grams per second (g/s). In an analogous way, a volumetric flow rate is the volume of a gas or liquid that flows in a certain amount of time, expressed in such units as litres per ... WebMany users choose Coriolis meters for gas flow measurement where measurement accuracy is highly valued. Coriolis flowmeters are available on the market today with accuracies as good as +/-0.35 percent. Higher gas supply pressures help to maintain that high accuracy over a wider turndown than lower pressure applications. iron earth fertilizerWebVolume flow in the common femoral artery was 434.4 mL/min; superficial femoral artery, 172.5 mL/min; popliteal artery, 92.1 mL/min; dorsalis pedis artery, 11.8 mL/min; and common plantar artery, 12.0 mL/min.
