ABSTRACT:
An electromagnetic flow meter is described having a pressure containing vessel or conduit through which the fluid to be metered is passed. The pressure containing vessel is formed of first and second sections which are made of respective materials having first and second magnetic permeabilities, such as stainless steel and carbon steel. A single magnetic field generating coil is provided adjacent the first section for generating a magnetic field across the pressure containing vessel.
