Paper Abstract

Accurate dosing of liquids in sub-microliter quantities requires a precise measurement of the dispensed quantities. This paper describes applications of a micro flow sensor based on the differential pressure measurement across a fluid restriction. The small size and high accuracy of the flow sensor are very attractive for the integration into sophisticated instrumentation. The use of well-developed hybrid assembly technologies allows for extreme miniaturization and high-density parallel measurements in multi-channel application.
