摘要：
A flow rate measurement device is configured to measure a flow rate of a gas flowing inside of a pipeline, and includes an ultrasonic transducer installed so as to be in contact with the pipeline, and a flow rate calculation part configured to calculate the flow rate of the gas according to a result of reception of ultrasonic wave from the ultrasonic transducer, wherein the ultrasonic transducer includes an ultrasonic oscillation part configured to emit the ultrasonic wave toward the inside of the pipeline and an ultrasonic reception part configured to receive the ultrasonic wave, and at least the ultrasonic oscillation part has a focusing part configured to focus the ultrasonic wave on a center of the pipeline.
