Flow Rate Measurement with Pressure Controllers in Microfluidics

In order to measure a flowrate while using a pressure-based flow control,  you would integrate a flow meter into the setup. Alternatively, the flowrate can be calculated or calibrated with scales.

Die Durchflusssensoren für die Mikrofluidik basieren auf unterschiedlichen Ansätzen. Die bekanntesten verwenden zwei Prinzipien:

– temperature-based flow measurement 

– Coriolis force-based flow measurement

Sometimes PIV (particle imaging velocimetry) can be used for the flow rate measurement in Microfluidics.
