1. An electromagnetic flowmeter comprising:
a flowtube configured to carry a flowing conductive fluid, the flowtube having a flowtube wall comprising a conductive material, the flowtube wall having an inner surface surrounding a fluid flow path for the conductive fluid;
a non-conductive liner positioned to electrically insulate the flowtube wall from the conductive fluid, the flowtube and non-conductive liner defining an electrode mounting hole;
an electrode extending through the electrode mounting hole, the electrode and the non-conductive liner forming a fluidic seal between the electrode mounting hole and the fluid flow path, at least a portion of the electrode being arranged in fluid communication with the flowtube within the electrode mounting hole.
