Abstract:
Calibration of a microfluidic meter is conventionally done with a precision reference such as a high accurate balance or a precise syringe pump system. These processes normally are very time consuming and are not the feasible approaches for high volume flow meter manufacture. In this paper, we will discuss the comparison of the calibration options of the thermal time-of-flight microfluidic meter including the precise syringe system, balance and Coriolis flow meter. The flow range of the meter covers from 20μL/min to 400mL/min. The comparison of the metrology features and the procedure of each system is discussed. Further, for the hygienic sensitive applications, the liquid calibration often leads to concerns for the cleaning procedure after the calibration. Comparison of the calibration with the calculated values and DI water and the conversion between the fluids is also discussed.
