ABSTRACT:
Pressure within a liquid containing vessel is determined by adding a solid precursor for at least one bubble to the liquid, retaining the precursor in the liquid for a sufficient time for it to form at least one bubble and generate a sonic signal, metering a characteristic of the sonic signal which is representative of the pressure in the liquid and determining the pressure in the liquid from the measured characteristic.
