摘要： An apparatus and method for noninvasively monitoring steam quality and flow and in pipes (12) or conduits bearing flowing steam (14), are described. By measuring the acoustic vibrations generated in steam-carrying conduits by the flowing steam either by direct contact (20) with the pipe or remotely thereto (16), converting the measured acoustic vibrations (32, 34, 36) into a frequency spectrum characteristic of the natural resonance vibrations of the pipe, and monitoring the amplitude and/or the frequency of one or more chosen resonance frequencies (36), changes in the steam quality in the pipe are determined. The steam flow rate and the steam quality are inversely related, and changes in the steam flow rate are calculated from changes in the steam quality once suitable calibration curves are obtained.

摘要： The present invention includes an apparatus and method for continuous and point level liquid level detection in a closed container or pipe having an inaccessible interior volume such that it is difficult to retrofit these tanks with a level gauge that 5 operates within the storage volume. The invention is based an a frequency domain analysis of the combined storage tank/fluid or pipe/fluid response to localized ultrasonic energy, and can be implemented using several excitation and signal analysis procedures, taking advantage of the transmission properties of the vessel wall in the vicinity of one of its longitudinal thickness resonances. Thus, significantly lower peak excitation voltages are required than with pulse-echo ultrasonic techniques.
