Abstract
The flow rate measuring apparatus according to one aspect of the present invention is a flow rate measuring apparatus that intermittently measures the flow rate of a fluid, comprising a heating unit for heating the fluid; a control unit that controls a drive voltage for driving the heating unit, or the interval at which the drive voltage is applied, to the desired value; a temperature sensing unit that senses information about the temperature of the heated fluid; and a flow rate measurement unit that measures the flow rate of the fluid on the basis of the sensing signal outputted from the temperature sensing unit, wherein, in intermittently measuring the flow rate, the control unit varies the heating amount of the heating unit in each measurement by varying the interval at which the drive voltage is applied.
