Abstract
A method and apparatus for remotely generating pressure signals in a fluid stream for telemetry purposes with minimal insertion loss and susceptibility to blocking flow of the fluid stream by providing a straight through acceleration path for the fluid stream followed by a straight through diffusion path, wherein pressure pulses representing data are generated by turbulence resulting from periodic disturbances made in the diffusion path.
