| 1. Non-intrusive apparatus for measuring parameters related to fluid flow in a conduit comprising:
an acoustic coupler located along the conduit and adapted for contact with the conduit;
a mechanical amplifier having an acoustic input coupled to the acoustic coupler and having an acoustic output;
an analog microphone coupled to the acoustic output and establishing first signals related to acoustic energy in the conduit;
and
a signal processor for receiving the first signals and comprising:
an analog amplifier for amplifying the first signals;
a digitizer for digitizing the first signals and generating a raw data stream;
and
at least a data processor for processing the raw data stream and generating second signals indicative of fluid flow in the
conduit.
