FLOW RATE MEASUREMENT IN A VOLUME

摘要

A system for measuring flow rate within a volume includes one or more transmission devices that transmit one or more signals through fluid contained within the volume. The volume may be bounded, at least in part, by an outer structure and by an object at least partially contained within the outer structure. A transmission device located at a first location of the outer structure transmits a first signal to a second location of the outer structure. A second signal is transmitted through the fluid from the second location to a third location of the outer structure. The flow rate of the fluid within the volume may be determined based, at least in part, on the time of flight of both the first signal and the second signal.

1. A method for measuring flow rate within a volume comprising:
transmitting, by a transmission device, a first signal through fluid contained within the volume, wherein the volume is bounded, at least in part, by an interior surface of an outer structure and an object at least partially located within the outer structure, wherein the transmission device is located at a first location on the outer structure; measuring a first time of flight of the first signal from the first location to a second location on the outer structure; propagating a second signal through the fluid from the second location to a third location on the outer structure; measuring a second time of flight of the second signal; and determining the flow rate of the fluid within the volume based, at least in part, on both the first time of flight and the second time of flight.
