H. Antlinger, B. Jakoby, R. Beigelbeck, S. Cerimovic & F. Keplinger
Sensors for online monitoring of fluid properties facilitate characterization, controlling, and optimization of many processes. Particularly, for industrial applications small, reasonably priced, and robust sensors are required. A lot of recent work has been focused on sensing viscosities of liquids (often in combination with their density), which can be used as characteristic parameter representing the state of the liquid to be monitored. Typically used laboratory equipment for viscosity measurements involve motor-driven rotating objects resulting in...
