摘要：
An arrangement for an inhaler comprises at least one electric evaporator for evaporating liquid supplied from the evaporator, and for adding the evaporated liquid to an air flow flowing through the inhaler to form an aerosol, and a flow rate measuring arrangement for measuring the volume and/or mass flow of the air flow flowing through the inhaler. The flow rate measuring arrangement comprises a heating device, a downstream temperature sensor arranged downstream of the heating device for measuring an air outlet temperature and an electronic control device, wherein the electronic control device is adapted to determine the volume and/or mass flow of the air flow flowing through the inhaler on the basis of a temperature difference between the air outlet temperature and an air inlet temperature of the air flow upstream of the heating device.
