The invention provides a turbo type flow control device which does not employ a valve core to control an actual flow and to aim to save electricity. In actual flow control, part of energy wasted by heating is recycled as electric energy to reutilize energy and to contribute to saving energy. The turbo type flow control device is provided with a power generation part (306) and a turbine (308). The power generation part (306) is provided with a rotor (6) and a stator (7). The rotor (6) is provided with a ring (6-1) with a permanent magnet and impellers (6-2) integrated on inner sides of the ring (6-1). The impellers (6-2) of the rotor (6) are used as the turbine (308). A definite flow changing values with load change of a supply object of a fluid is used as input; a real flow of a fluid passing through a flow path is estimated according to a current angular speed of the turbine (308) and a current torque of the power generation part (306), so as to control the torque of the power generation part (306) which all
