  • Patent number: 9016131
    Abstract: At least two sound pressure sensors in parallel with each other are inserted into a liquid to which waves are applied. The sound pressure sensors have a bar-like shape and the same sensitivity. In a first synchronized state waves detected by the sound pressure sensors are synchronized with each other. The sound pressure sensors are moved relative to each other in a longitudinal direction, to break the first synchronized state and then establish a second synchronized state in which the waves detected by the sound pressure sensors are again synchronized with each other. A wavelength of the detected waves is determined according to a quantity of the relative movement of the sound pressure sensors between the first and second synchronized states. The detection of a wavelength of waves applied to the liquid is usable to evaluate and control a total amount of dissolved gases in the liquid.
