Abstract: A magnetic flowmeter includes a pipe with a non-conductive PTFE liner, magnetic coils to generate a magnetic field, and electrodes in contact with the fluid on opposite sides of the pipe. The electrodes comprise conductive PTFE patch electrodes bonded to the non-conductive PTFE liner so that an inner end of each patch electrode is exposed to fluid flowing through the interior pipe and an outer end of each patch electrode is aligned with an electrode hole in the pipe.

Abstract translation: 磁流量计包括具有非导电PTFE衬垫的管，产生磁场的磁线圈和与管相对侧的流体接触的电极。 电极包括结合到非导电PTFE衬垫的导电PTFE贴片电极，使得每个贴片电极的内端暴露于流过内管的流体，并且每个贴片电极的外端与管中的电极孔对准 。
