Resonant Measurement of Liquid Properties in a Fluidic Sensor Cell

Proc. Eurosensor XXII 2008, Dresden
A sensor cell for the measurement of mass density and viscosity is modeled and the results are experimentally verified. Two polymer diaphragms, constituting the top and bottom of the sensor cell, carrying conductive paths exert time–harmonic forces on the sample liquid. The resulting motion is read out using the induced voltage in a secondary path on the diaphragm. The fluid motion analysis is based on potential flow and shear waves at the boundary layer.
