ABSTRACT:
In an electromagnetic flowmeter using a ceramic pipe as a measuring pipe, an electrode inserted in the ceramic pipe includes a ceramic core rod and a conductive portion of a refractory metal. The conductive portion covers a fluid contact end face of the core rod and extends along the longitudinal direction of the core rod. The other end of the conductive portion faces an outer surface of the ceramic pipe, and is opposite the fluid contact end face.
