Abstract: Ultrasonic flowmeter includes fluid flow path through which a measurement target fluid flows and a pair of ultrasonic transducers that can transmit and receive an ultrasonic signal. The ultrasonic flowmeter further includes flow rate calculator that calculates a flow velocity or flow rate of a measurement target fluid. In addition, fluid flow path includes a main flow path including a plurality of divided flow paths obtained by dividing a flow path having a rectangular cross-section by the same width, and a sub flow path including an added flow path having the same width as that of the divided flow path and having a height lower than that of the divided flow path. Furthermore, flow rate calculator calculates the flow rate of the measurement target fluid flowing through the fluid flow path from the flow velocity or flow rate of the measurement target fluid obtained based on the propagation time.
