  • Apparatus for measuring gas density and sugar content of a beverage within a sealed container and method of measuring the same
    Patent number: 5369600
    Abstract: An apparatus and method in which the lateral surface of a sealed container (11) containing a beverage liquid (12) is pressed (21, 22) for deformation to measure the internal pressure (P) of the container, and displacement caused by the pressure and the load (F, 31) applied by the pressure is detected (35) so that the gas density of the beverage liquid may be evaluated from these values. An ultrasonic pressure wave is applied (111) to the sealed container to measure the sugar content of the beverage from the propagation velocity of the pressure wave received by an ultrasonic receiver (112), container surface temperature and the ambient temperature resulting from sensors (121, 122) and a calculation unit (50). For simultaneously measuring the gas density and the sugar content a gas density measuring unit (220, 230, 240) and a sugar content measuring unit (290) are provided.
