To provide a flow rate measuring device capable of reducing a measurement time of an injection amount even when measurement of an injection amount is performed while changing an injection condition.
A control part 70 calculates a calorific value included in a measurement fluid to be injected from an injector 100 and provided to the measurement fluid in a pressure vessel 20 by the injection for each of a plurality of measurement injection conditions by multiplying a target measurement injection amount Vmj by a target measurement injection pressure Pmj. The control part 70 sets an auxiliary injection condition of an auxiliary injector 60 comprising an auxiliary injection amount Vaj and an auxiliary injection pressure Paj so that the difference in the calorific values becomes small for each of the plurality of measurement injection conditions. The control part 70 performs the injection from the injector 100 in accordance with the plurality of measurement injection conditions, and performs the auxiliary injection from the auxiliary injector 60 in accordance with the auxiliary injection condition set for each of the plurality of measurement injection conditions.
