  • Publication number: 20190196517
    Abstract: A calibration data generation apparatus includes a flow rate sensor that measures the flow rate of a fluid flowing through a fluid control valve; a differential pressure control mechanism; a temperature control mechanism; and a control unit that when the fluid passing has sound velocity, uses the temperature control mechanism to change the temperature from a reference temperature to comparative temperature. In addition, the control unit includes a valve opening control part that controls the fluid control valve so that at the comparative temperature, an output value outputted from one of the position sensor and the flow rate sensor becomes equal to the reference output value of the one; and a calibration data generation part that generates the calibration data on the basis of a calibration data generation output value outputted from the other one of the position sensor and the flow rate sensor.
