Abstract
A system for measuring the flow rate in a microfluidic pipe having n pressure sensors arranged in series on a pipe and measuring the pressure Pi of the liquid passing through same. These sensors being separated from one another by pipe portions Ri. Each pipe portion having a hydraulic resistance Rhi, thus making it possible to measure the pressure variations or head loss ΔPi between two consecutive sensors of the liquid flowing successively through these hydraulic resistances. The comparison between the estimated flow rates Di=ΔPi/Ri, making it possible to determine the fouling of the microfluidic pipe.
