ABSTRACT:
An improved pycnometer in which the sample whose volume to be measured is put in a closed chamber to which an electro-mechanical transducer is coupled. The transducer is excited at a constant frequency. The change in impedance of the transducer is then read as a function of the volume of the sample.
