SYSTEM FOR MEASURING THE FLOW RATE OF LIQUID IN A MICROFLUIDIC PIPE
The present invention relates to a system for measuring the flow rate in a microfluidic pipe, comprising n pressure sensors Ci (C1, C2, ..., Cn) arranged in series on a pipe and measuring the pressure Pi (P1, P2, ..., Pn) of the liquid passing through same, these sensors being separated from one ano...

| description | The present invention relates to a system for measuring the flow rate in a microfluidic pipe, comprising n pressure sensors Ci (C1, C2, ..., Cn) arranged in series on a pipe and measuring the pressure Pi (P1, P2, ..., Pn) of the liquid passing through same, these sensors being separated from one another by pipe portions Ri (R1, R2, ..., Rn-1), each having a hydraulic resistance Rhi (Rh1, Rh2, Rhn-1), thus making it possible to measure the pressure variations or head loss ΔΡi (ΔΡ1, ΔΡ2, ..., ΔΡn-1) between two consecutive sensors of the liquid flowing successively through these hydraulic resistances, the comparison between the estimated flow rates Di = ΔΡi/Ri (D1, D2, ..., Dn-1) making it possible to determine the fouling of the microfluidic pipe.
La présente invention porte sur un système de mesure de débit dans une canalisation micro fluidique comportant n capteurs de pression Ci (C1, C2,..., Cn) disposés en série sur une canalisation et mesurant la pression Pi (P1, P2,... Pn), du liquide les traversant, ces capteurs étant séparés entre eux par des portions de canalisation Ri (R1, R2,..., Rn-1) présentant chacune une résistance hydraulique Rhi (Rh1, Rh2, Rhn-1), permettant ainsi de mesurer les variations de pression ou perte de charge ΔΡί (ΔΡ1, ΔΡ2,..., ΔΡη-1) entre deux capteurs consécutifs du liquide s'écoulant successivement à travers ces résistances hydrauliques, la comparaison entre eux des débits estimés Di = ΔΡϊ/Ri (D1, D2,..., Dn-1) permettant de déterminer l'encrassement de la canalisation micro fluidique. |
