  • System and method for calculating flow velocity
    Patent number: 10371551
    Abstract: A system and method for calculation of flow rate comprising at least two ultrasonic sensors, ultrasonic transmit receive device, and signal processing device. At least two ultrasonic sensors are installed on the pipe where the fluid is flowing through, and at least two ultrasonic sensors contain different ultrasonic beam paths, further, the ultrasonic beam paths of at least two ultrasonic sensors contain the overlap area. The ultrasonic transmit and receive device is used to actuate at least two ultrasonic sensors, and is used to transmit one or multiple ultrasonic signals to pipes via one or multiple of at least two ultrasonic sensors, further, to receive ultrasonic signal via at least two ultrasonic sensors. The signal processing device is used to process the ultrasonic signal received, further, to calculate the flow rate of the fluid precisely.

  • ULTRASONIC METHOD AND DEVICE FOR MEASURING FLUID FLOW
    Publication number: 20170343397
    Abstract: A method of measuring a flow rate of a fluid flowing in a space between an outer conduit and an inner element in the outer conduit is provided. Ultrasonic waves are transmitted and received through the space between multiple pairs of ultrasonic transducers along multiple propagation paths, respectively. A mean line velocity of the fluid is calculated based on data from each pair of ultrasonic transducers. As such, multiple mean line velocities across the space are obtained. The flow rate of the fluid is calculated based on the multiple mean line velocities.
