A vortex flow includes a flowtube configured to receive a flow of process fluid. A shedder bar is disposed within the flowtube and is configured to generate vortices in the flow of process fluid. A vortex sensor is disposed to sense vortices in the flow of process fluid generated by the shedder bar. Measurement electronics are operably coupled to the vortex sensor and are configured to detect an analog signal of the vortex sensor and provide a digital indication relative to the analog signal of the vortex sensor. A processor is configured to receive the digital indication and calculate velocity of the process fluid flow based on a frequency of the digital indication. The processor is also configured to measure an amplitude of the digital indication and estimate density of the process fluid based on the measured amplitude. The processor is further configured to determine a fluid type based on the measured amplitude and assign a unit of flow corresponding to the calculated velocity to a fluid totalizer corresponding to the detected fluid type.
