Torsional Waveguide Density Sensor
  • Radek Glaser
As a part of National Science Foundation-Research for Undergraduates program, a torsional wave guide density sensor has been investigated in the Laboratory of Surface Science and Technology at the University Of Maine. This simple design uses torsional piezo-electric transducers to generate torsional mode in a long circular rod.
The non-circular portion of the wave guide allows for the measurement of different properties of fluids. Theory is presented from energy balance perspective and from the acoustic wave propagation approach. A series of experiments have been conducted with variety of liquids and gases. Several relationships have been verified and also new have been developed.
I would like to express my gratitude to my advisors: Mr. Lawrence Lynnworth, Professor John Vetelino and William Spratt for their patience and priceless assistance during the span of the project.
