Abstract

An electromagnetic flowmeter for mass flow measurement of a flowing medium having a measuring tube (1), a magnetic field generator for generating a magnetic field that at least partially passes through the measuring tube (1), two magnetic coils (2), and two electrodes for tapping into a measurement voltage induced in the flowing medium. The measuring tube (1) is designed as an integrally molded metal pipe or as a metal pipe produced integrally by hydroforming. Preferably, the measuring tube has a wall thickness that is smaller at a mid-section than at its ends, and reinforcing ribs in the mid-section.
