  • Patent number: 11175165
    Abstract: Methods and systems for measuring a fluid flow comprise a plurality of transceivers disposed at predetermined locations distributed along a perimeter around the fluid flow. The transceivers transmit and receive acoustic signals through the fluid flow there between. A plurality of different acoustic paths through the fluid flow are formed between different transceiver pairs. Different time intervals are measured between respective times of transmitting and receiving the acoustic signals; and along the plurality of different acoustic paths. A velocity map of the fluid flow is calculated by fitting the measured different time intervals to a model of the fluid flow. The model of the fluid flow defines a velocity map with different flow velocities in a cross-section plane transverse to the fluid flow.
