Abstract
An acoustic transducer for measuring a property of a fluid includes an acoustic pulse generator and buffer assembly. The buffer assembly is between the pulse generator and the fluid. The buffer assembly is composed of a core and a sleeve shrink fitted over the core to form a cladding layer. The cladding layer reduces dispersion of the acoustic pulses traveling through the core.
