Abstract: In a method for determining mass flow with a Coriolis mass flow measuring device arranged on a rotary filler, a correction value ?{dot over (m)} is ascertained, which is proportional to the RPM n of the rotary filler. This correction value is subtracted from the conventionally ascertained value {dot over (m)} of the mass flow. The corrected measured value {dot over (m)}corr is thus {dot over (m)}corr={dot over (m)}??{dot over (m)}.

It comprises a vibratory transducer with at least one flow tube for conducting the fluid, which communicates with the pipe.
