Abstract
A system for monitoring the presence of deposits or buildup on the inside wall of a fluid-containing pipe comprises a pair of acoustic transmitters outside of the pipe and spaced apart along the length of the pipe and capable of transmitting an acoustic signal into the pipe wall, a pair of acoustic receivers outside of the pipe and spaced apart along the length of the pipe and capable of receiving an acoustic signal from the pipe wall, and a power source for causing the transmitters to transmit a signal. A method for monitoring the presence of deposits or buildup on the inside wall of a fluid-containing pipe, comprises (a) providing first and second acoustic transmitters outside of the pipe and spaced apart along the length of the pipe and capable of transmitting an acoustic signal into the pipe wall, (b) providing first and second acoustic receivers outside of the pipe and spaced apart along the length of the pipe and capable of receiving an acoustic signal from the pipe wall, (c) transmitting a first signal from the first transmitter, (d) measuring the amplitude of the first signal received at the first and second receivers as A11 and A12, respectively, (e) transmitting a second …
