A method for the acoustic data transmission via pipelines with external coupling of the sound transducer

摘要

The present invention relates to a process for the acoustic data transmission via pipelines with external coupling of the sound transducer, which makes it possible, by means of sound transmission via the pipe casing and / or the enclosed medium (digital or analog) signals to transmit. Applications could here signals for the regulation or - control system or the transmission of counts. As a transducer are - of a piezo elements or dynamic transducer in question, the possibly by means of suitable media or matching elements with the tube or the tubes are connected. This makes it possible, in particular, also a impedance matching.
