An ultrasonic flowmeter having a first propagation time measurement unit (11) that measures a first propagation time being a time until ultrasonic waves transmitted from a first ultrasonic sensor (2) propagate a fluid to be measured and are received by a second ultrasonic sensor (3). The ultrasonic flowmeter also has a second propagation time measurement unit (12) that measures a second propagation time being a time until ultrasonic waves transmitted from a second ultrasonic sensor (3) propagate the fluid to be measured and are received by the first ultrasonic sensor (2). The first propagation time measurement unit (11) and the second propagation time measurement unit (12) are arranged inside the same semiconductor (13), and the ultrasonic flowmeter also comprises a delay time measurement unit (14) that measures the semiconductor delay time. |
