ABSTRACT:
A mass flowmeter includes a hollow flow tube with a contoured longitudinal bore. Inserted into the contoured longitudinal bore are preferably four rods. The rods establish stable axial vortices within the hollow flow tube. Pressure pulses on the flow rods produced by the vortical flows are measured by pressure transducers and associated electronics then translated into an accurate measurement of mass flow. Total wide ranging flow stability and high signal output characterize this mass flowmeter as well as its ability to handle liquids, gases, and fluidized solids.
