The controller 5 operates a volume knob 10 according to the flow rate detected by the sensor 2 as well as the flow rate set 11 at a flow rate setting part 4 so that a real flow rate is equal to the set flow rate. Then the resistance is varied to give the phase control 14 to the voltage, and the rotational frequency of the pump 3 is varied. Therefore the real flow rate can be controlled to a set flow rate, i.e., a constant flow rate. Furthermore the controller 5 can vary the set flow rate with operation of the knob 10.
