  • Publication number: 20220136988
    Abstract: It is possible to reduce a decrease in accuracy of measuring the concentration of a measurement target gas even in a case where, in a mixture of gases, there is a gas greatly different from another gas in a rate of change in thermal conductivity with respect to temperature. The concentration measurement device includes a sensor configured to measure the concentration of a measurement target gas in a mixture of gases on the basis of thermal conductivity of the measurement target gas, the mixture of gases including two or more components, and a heating unit configured to heat the mixture of gases so that the concentration of the measurement target gas can be uniquely determined with respect to the thermal conductivity.

  • Patent number: 11112285
    Abstract: A flow measurement device includes a flow sensor that senses a flow rate of a measurement target fluid flowing through a main channel, a characteristic-value obtaining unit that includes a heater heating the target fluid and a temperature sensor sensing a temperature of the target fluid, and obtains a characteristic value of the target fluid, and a flow rate correction unit that corrects a flow rate of the target fluid calculated based on a sensing signal from the flow sensor using the characteristic value of the target fluid obtained by the characteristic-value obtaining unit. The heater and the temperature sensor are arranged parallel to each other in a direction orthogonal to a flow direction of the target fluid. The characteristic-value obtaining unit obtains the characteristic value based on a difference between the temperatures of the target fluid sensed by the temperature sensor before and after the heater temperature is changed.
