ABSTRACT:
A sensor system immersible in an ambient-fluid for sensing at least two conditions of the ambient fluid, includes a sealed chamber filled with a reference fluid of a known composition and/or pressure, and two acoustic transmission channels, one including the reference fluid, and the other including the ambient fluid. Measuring circuitry measures (a) the transit time of an energy wave through one transmission channel to determine the temperature of the fluid within the sealed chamber and thereby the temperature of the ambient fluid; and (b) the transit time of an energy wave through the other transmission channel to determine the composition and/or the pressure of the ambient fluid.
