DOPPLER FLOW METER AND METHOD

摘要

DOPPLER FLOW METER /A METHOD A catheter probe flow meter and method of determining the volume flow of a fluid through a conduit, at least one of the fluid and the conduit having energy-scattering interfaces. The method in one embodiment includes transmitting at least two and receiving at least one or transmitting at least one and receiving at least two sound beams through the fluid, resolving the Doppler vectors into an average velocity vector for each transmitting/receiving combination, and resolving the resolved velocity vectors into their component parts.
