摘要：A pump device and method for stabilizing a suction flow rate irrespective of anoutside air temperature. The method includes: outputting a drive signal for driving a

motor at a rotation speed for discharging gas of the reference flow rate from the suctionport of the pump main body; measuring a temperature of gas discharged from thesuction port or a temperature of the pump main body by a temperature sensor attachedto the pump main body; calculating an actual flow rate of the gas discharged from thesuction port based on a temperature signal relating to the temperature of the gasincluded in an output of the temperature sensor; and correcting the drive signal such thatthe actual flow rate equals the reference flow rate and outputting the corrected drivesignal to the motor.
