Abstract
The invention relates to a method for operating a magneto inductive flow measuring device and to a magneto inductive flow measuring device, wherein at least one magnet system having at least one coil produces a periodically polarity changing magnetic field extending essentially perpendicularly to a longitudinal axis of the measuring tube for inducing a flow dependent voltage in the medium, wherein in a measuring phase for registering at least one voltage value for ascertaining flow velocity or volume flow an essentially constant magnetic field is produced, which is reverse poled in a polarity reversal phase, wherein energy supply during the polarity reversal phase occurs completely from a capacitor.
