Abstract: An ultrasonic device for measuring the rate of flow of fluid in a duct employs an ultrasonic signal transmitter and two ultrasonic signal receivers operating simultaneously, and the respective energy paths joining the receivers with the transmitter form predetermined angles of inclination with respect to the axis of the duct. Phase differences between the signals received by the receivers, and the pressure of the fluid in the duct, are used to form an output signal indicative of the mass flow rate of fluid in the duct.
