Abstract
A method of determining the flow rate of a fluid in a conduit. Ultrasonic energy is directed through the conduit along multiple paths. The ultrasonic energy is detected and measured using a range gated Doppler technique to determine the velocity of the fluid at several points in the conduit. These point velocities are used to calculate the average flow rate of the fluid in the conduit.
