A magnetic-inductive flowmeter for ascertaining flow velocity and/or volume flow of a medium includes a measuring tube for conveying the medium, a magnetic field producing means and at least one electrode assembly, which is installed in the measuring tube in such a manner that it forms a galvanic contact with the medium, wherein the electrode assembly has an electrode body, wherein the electrode body is stylus-shaped and has a front end surface, characterized in that a pressure measuring transducer is coupled with the electrode body, wherein the pressure measuring transducer is contactable with the pressure acting on the front end surface, and the electrode assembly includes a temperature sensor, which is adapted to ascertain a measurement signal dependent on temperature of the medium.
