Abstract

A convenient method for measuring the isothermal bulk modulus and the isobaric heat expansion coefficient is shown using a vibrating microsensor system that measures fluid density versus applied pressure and temperature. In contrast to the conventional volume-change method, the fluid properties are measured locally in the vicinity of the sensor, such that inflation of vessels due to high hydraulic pressures, or the influence of entrained air on the measured bulk modulus are reduced.
