TL;DR: In this paper, a differential pressure liquid flow sensor has been fabricated on a polyimide membrane and a test device has been tested with a piezoelectric micropump for flow rates from 30 µl h−1 to 300 µl H−1.

TL;DR: A liquid flow sensor based on the measurement of the pressure difference across a flow restriction integrated between two silicon pressure sensors is presented in this paper, which is used in a system consisting of a silicon micro-pump and an electronic controller.

TL;DR: It is shown that this technology now has reached a certain maturity that enables instrument performance far superior to what would be achievable with conventional methods, and a hybrid solution that merges silicon technology with classical fine mechanical machining is most suited.

TL;DR: A system for accurate low-volume delivery of liquids in the micro- to nanoliter range makes use of an integrated miniature flow sensor as part of an intelligent feedback control loop driving a micro-solenoid valve.

TL;DR: The performance and the use of microtechnology in a miniaturized bioreactor developed for the continuous cultivation of yeast cells, Saccharomyces cerevisiae, in microgravity is described.
