System and method for corrosion and erosion monitoring of fixed equipment

A method to assist a monitoring controller in detecting localized corrosion, comprising a processor, and a memory storing computer-executable instructions that, when executed by the processor, cause the monitoring controller to perform steps comprising:

• generating a short spike signal that activates, by an intelligent amplified multiplexer, a first transducer affixed to a fixed equipment;
• generating a smooth low-frequency analog waveform signal that activates, by the intelligent amplified multiplexer, a first of a plurality of second transducers affixed to the fixed equipment at locations in proximity to the first transducer;
• in response to the generating of the short spike signal, receiving an indication of a thickness measurement of the fixed equipment based on measuring time-of-flight;
• and
• in response to the generating of the smooth low-frequency analog waveform signal an indication of localized corrosion of the fixed equipment by a change of signal characteristics next to the time-of-flight;
• wherein the intelligent amplified multiplexer receives high current, high voltage inputs and is configured to selectively activate one of:
• the first transducer and one of the plurality of second transducers.

A method performed by a probe assembly permanently affixed to a component that transports materials, the probe assembly comprising a memory storing computer-executable instructions that, when executed by a controller of the probe assembly, cause the probe assembly to perform steps comprising:

• activating, by an intelligent amplified multiplexer, at least one first transducer of the probe assembly affixed to the component, in response to receiving a short spike signal;
• activating, by an intelligent amplified multiplexer, a first of a plurality of at least one second transducer of the probe assembly affixed to the component, in response to receiving a smooth low-frequency analog waveform signal;
• in response to the activating of the first of the plurality of the at least one second transducer, measuring, by a second of the plurality of the at least one second transducer, a first echo signal received through the component, wherein the first echo signal has a first time of flight and a first amplitude;
• in response to the activating of the first of the plurality of the at least one second transducer, measuring, by a third of the plurality of the at least one second transducer, a second echo signal received through the component, wherein the second echo signal has a second time of flight and a second amplitude;
• processing, by an amplifier and the controller, the first echo signal and second echo signal by baseline subtracting and digital filtering into a combined echo signal;
• and
• transmitting the combined echo signal, wherein the combined echo signal is an indication of localized corrosion in the component.
