Abstract
In a method for determining mass flow with a Coriolis mass flow measuring device arranged on a rotary filler, a correction value Δ{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)}−Δ{dot over (m)}.
Claims3
A method for determining mass flow with a Coriolis mass flow measuring device arranged on a rotary filler, comprising the steps of:
- conventionally determining mass flow {dot over (m)} with the Coriolis mass flow measuring device;
- ascertaining RPM n of the rotary filler;
- calculating a correction value Δ{dot over (m)}=k*n, with a constant k;
- and
- determining corrected mass flow {dot over (m)}corr with {dot over (m)}corr={dot over (m)}−{dot over (m)}.
