  • Liquid supply apparatus and method of detecting fault thereof
    Patent number: 8087549
    Abstract: In a liquid supply apparatus, a liquid held in a liquid holding portion is pushed out to the exterior by pressurized gas. The apparatus includes a liquid pouring section for pouring a predetermined amount of liquid into an intermediate portion of the liquid holding portion, a liquid discharge portion which comprises a thin pipe smaller in flow passage cross-sectional area than the liquid holing portion, and is connected to one end of the liquid holding portion, a liquid storing portion which is larger in flow passage cross-sectional area than the liquid holding portion, and is connected to the other end of the liquid holding portion, and a gas feed section for feeding the pressurized gas into the liquid storing portion. The apparatus further includes at least one of first fault detection section for detecting a fault of the liquid pouring section and second fault detection section for detecting a fault of the gas feed section.
    Type: Grant

  • Method of measuring flow rates of respective fluids constituting multiphase fluid and flow meter for multiphase flow utilizing same
    Patent number: 6467358
    Abstract: A flow meter for a multiphase flow which comprises a cross-correlation flow meter (26) for measuring basic values to calculate component ratios of respective fluids constituting a multiphase fluid (2) comprising a gas and a plurality of liquids in a pipe (1) through which the multiphase fluid flows; and an arithmetic circuit (22) for calculating flow rates of the respective fluids, which acquires information concerning ratios of liquid phase components of the multiphase fluid (2) on the basis of both measured values obtained by the cross-correlation flow meter (26) at an instance when the pipe (1) is filled with liquid alone during the passage of the multiphase fluid (2) through the pipe (1) provided with the cross-correlation flow meter (26) and characteristic values of the respective fluids of the multiphase fluid (2), acquires information concerning ratios of the respective fluids from a time average of the measurements obtained by the cross-correlation flow meter (26) and the respective characteristic val
