Abstract
A vortex shedding flowmeter has a vortex sensor with a cantilever mounted transducer vane comprising a piezoelectric polymer film laminated together with an elastic substrate and that is encapsulated in an elastomeric integument to enable the transducer vane to withstand vortex pressure fields that span more than three orders of magnitude with sensitivities that provide high turn down ratios.
