ABSTRACT:
A magnetoinductive flowmeter encompasses a ceramic measuring tube as a conduit for a medium whose flow rate is to be measured, and a measuring electrode featuring a cermet body. The measuring tube is mounted in the wall of the measuring tube with its side that faces the medium conductively or capacitively connecting to the medium while its side facing away from the medium connects to a measuring line. The cross-sectional surface area of the cermet body is larger at its end facing the medium than at its other end facing away from the medium. The result is a measuring electrode that fully meets the respective requirements at either end notwithstanding minimized material consumption in making the electrode. A method for producing a measuring tube for the flowmeter is also disclosed.
