    Abstract: The flow regulating structure comprises a plurality of rail structures. Each rail structure has a plurality of rod-shaped members that are arranged side-by-side with the same direction of extension. The plurality of rail structures are disposed along the direction of gas travel in overlapping positions with space therebetween. The extension directions of the rod-shaped members differ between adjacent rail structures. In each rail structure, the plurality of rod-shaped members are arranged side-by-side with the same direction of extension in both a first virtual plane and a second virtual plane, which face one another in the direction of gas travel, and when viewed from the direction of gas travel, the rod-shaped members disposed on the second virtual plane are positioned between adjacent members among the plurality of rod-shaped members disposed on the first virtual plane.

    Abstract: A variable value calculating process includes: measuring a propagation time of the propagation of an ultrasound wave through a measurement sector inside a housing; obtaining a temperature calculated value on the basis of the measured value of the propagation time and a reference distance for the measurement sector; obtaining a temperature measured value by measuring the temperature inside the housing; and obtaining a temperature replacement fluctuation value indicating a difference between the temperature calculated value and the temperature measured value. The variable value calculating process is executed for each of a plurality of temperature conditions under which the temperature of a reference gas inside the housing differs. A temperature compensation table in which the temperature of a gas to be measured is associated with a temperature compensation value relating to the temperature is obtained on the basis of the temperature replacement fluctuation values obtained under each temperature condition.

    Abstract: This gas concentration measurement device comprises: a concentration measurement space; a transmission unit which transmits an ultrasonic wave to the concentration measurement space in response to a transmission signal; a reception unit which receives the ultrasonic wave propagated through the concentration measurement space, and outputs a reception signal; and an analysis unit. The analysis unit obtains a space propagation time in the concentration space on the basis of a timing at which the transmission signal is input to the transmission unit and a timing at which the reception signal is output from the reception unit, and obtains the concentration of a gas to be measured on the basis of the space propagation time. The analysis unit obtains a correction value for a direct wave-type propagation time on the basis of the direct wave-type propagation time and a reflective wave-type propagation time.

    Abstract: A gas concentration measurement device comprises: a transmission unit which transmits ultrasonic waves to a concentration measurement space; a reception unit which receives the ultrasonic waves propagated through the concentration measurement space and outputs a reception signal; and a concentration measurement unit which determines the spatial propagation time during which the ultrasonic waves propagate through the concentration measurement space and determines the concentration of the gas on the basis of the spatial propagation time. The concentration measurement unit determines the degree of approximation between a reception signal and a time shift signal to which time shift process has been applied, determines the time difference of pulses of neighboring reception signals on the time axis on the basis of the degree of approximation to the minimum shift time in the time shift process, and determines the spatial propagation time on the basis of this time difference.

    Abstract: The gas-liquid separator comprises: a swirl structure that causes a gas heading from upstream to downstream to swirl about a flow axis heading from upstream to downstream; a separation structure that discharges outward liquid components contained in the gas passing through the swirl structure; and a deflection structure that is provided downstream of the swirl structure and deflects the gas that has passed through the swirl structure. The deflection structure is provided with: a narrowing core portion that has a three-dimensional shape which narrows from upstream to downstream; and deflecting fins that are provided to the side surface of the narrowing core portion and deflect the gas in the opposite direction to the swirling direction resulting from the swirl structure.
