Consequently, the vortex shedding frequency to be evaluated is dependent solely upon the flow
velocity and not at all upon media density and viscosity.
The local changes in pressure induced by vortex shedding are detected by a piezo sensor and
converted into electrical pulses corresponding to the vortex frequency.
The frequency signal from the flowmeter sensor, which is proportional to the flow, undergoes
downstream processing in the transmitter.
