ABSTRACT:
A flowmeter determines the density of a fluid stream by periodically shifting a carrier sonic signal at a carrier modulation frequency and detecting the peak received energy after the carrier sonic signal traverses the stream. The flowmeter may additionally determine the temperature, volumetric flow, and mass flow of the fluid stream.
