Abstract
A Doppler array flowmeter system that includes a phased array antenna coupled to a conduit. The phased array antenna includes a plurality of transducers that produce an acoustic beam by emitting a respective first acoustic signal. The transducers receive respective second signals, wherein the second signals are frequency shifted reflections of the first acoustic signals off of particulate in a fluid. A controller couples to the plurality of transducers and compares the first acoustic signals to the second signals to determine a volumetric flowrate of the fluid through a conduit.

A system, comprising:
- a Doppler array flowmeter system, comprising:
- a conduit configured to carry a fluid;
- a phased array antenna coupled to the conduit, wherein the phased array antenna comprises a plurality of piezoelectric transducers configured to produce an ultrasonic beam by emitting a respective first ultrasonic signal, and wherein the piezoelectric transducers are configured to receive respective second signals, wherein the second signals are frequency shifted reflections of the first ultrasonic signals off of particulate in the fluid;
- and
- a controller coupled to the plurality of piezoelectric transducers, wherein the controller is configured to compare the first ultrasonic signals to the second signals to determine a volumetric flowrate of the fluid through the conduit.
