A magnetic flowmeter 10 includes a pipe 12 with a non-conductive PTFE liner 14, magnetic coils 18A, 18B to generate a magnetic field, and electrodes 16A, 16B in contact with the fluid on opposite sides of the pipe 12. The electrodes 16A, 16B comprise conductive PTFE patch electrodes 30A, 30B 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 12 and an outer end 38 of each patch electrode 30A, 30B is aligned with an electrode hole 32 in the pipe 12. |
