Claim:
1. An in-medium monitoring system for monitoring material carried within a pipe, comprising: an acoustic device installed within the pipe and configured to at least generate a voltage signal indicative of a condition of the material, the condition indicative of extrinsic properties of the material; a hardware unit including a detector module and a communication module, wherein the detector module includes a voltage to frequency converter configured to receive the voltage signal and output a modulated frequency signal that is modulated with data indicative of the condition of the material extracted from the voltage signal, and wherein the hardware unit further includes a log detection amplifier configured to receive the modulated frequency signal and to concurrently demodulate the modulated frequency signal in AM and FM modes; a switch connected to the acoustic device for switching the voltage signal to the hardware unit; and a power source for the acoustic device, the hardware unit and the switch, wherein the hardware unit and power source are attached to the pipe.
