Variable nozzle hole type fuel injection nozzle

A flowmeter which obtains the flow rate of a fluid by detecting the rotational speed of an impeller is provided with a transmitter for transmitting a laser beam or ultrasonic wave to the tip end of the rotating impeller, a receiver for capturing the laser beam or ultrasonic wave reflected by the impeller, and a data processing unit for calculating the difference between the frequency of signals captured by the receiver and the frequency of signals transmitted by the transmitter and for calculating the rotational speed of the impeller based on the calculated values.
