Abstract
Integrated acoustic emission transducer apparatus and methods are described. An example integrated external preamplifier device includes a data extractor, a process variable determiner, a status indication determiner, and a presentation device. The integrated external preamplifier device receives an acoustic emission signal generated via an acoustic emission sensor operatively coupled to the integrated external preamplifier device. The data extractor extracts signal data from the acoustic emission signal. The process variable determiner determines process variable data based on the extracted signal data. The process variable data includes at least one of flow rate data, flow capacity data, flow area data, flow velocity data, mass accumulation data, or volume accumulation data. The status indication determiner determines status indication data based on the process variable data. The presentation device presents at least one of the process variable data or the status indication data at the integrated external preamplifier device.
