Abstract
A thermal type flow meter includes a first resistor (R) is disposed along a flow path through which a fluid flows, generating heat when a current is applied, and outputting a first output signal indicating a heat generation temperature, a second resistor (R) disposed at a position different from that of the first resistor along the flow path and outputting a second output signal indicating a temperature of the fluid, and a current application unit configured to apply a current to the first resistor so that the first output signal indicates a predetermined temperature. A parameter for converting the difference between the first output signal and the second output signal when a predetermined input is received if the current is applied into a target value is determined. The flow rate is acquired using the parameter, the difference detected after the parameter is determined, and a predetermined function.
