System and method of metering with array of transducers

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.
