ABSTRACT:
The current invention relates to a conductivity-dielectric (CD) electrode design with apertures that allow compressional waves to propagate away from the surface of the acoustic wave device unimpeded. This prevents reflection of compressional waves that would interact with the viscosity sensor surface, thus altering the device response. It allows compressional waves to pass through, and allows the dual mode viscosity sensor responses to be utilized for density/viscosity/elasticity measurement and correlation. The invention further offers methods of instrumentation to detect unwanted reflections, to compensate, and to correct for the distortions caused by reflections. Finally, the invention provides a system and method for utilizing deliberately introduced reflections to obtain additional information, including fluid density.
