Abstract: The present disclosure recites a method for time controlled carrying out of a filling process including steps of beginning a first flow measurement before or during the start of a filling of a first container, starting the filling of the first container at a first point in time, and ending the filling of the first container at a second point in time, wherein the second point in time is predetermined by a set, first time interval. The starting and ending steps are repeated for filling a second container. The method also includes ending the first flow measurement and ascertaining a total flow of the preceding fillings, comparing an actual value ascertained from the total flow a predetermined, desired value, and-adapting the first time interval based on the comparing step. An apparatus according to the present disclosure includes a control setup for time controlled fill amount control and a flowmeter.

Abstract: The present disclosure relates to a method for operating a magnetic-inductive flow meter for measuring the flow rate or the volumetric flow of a medium in a measuring tube and to such a flow meter, wherein the medium is acted upon by magnetic fields of different polarity and field strength, wherein the alternation between magnetic fields causes a voltage pulse in the medium, wherein a voltage pulse during a phase without a magnetic field is used for calculation of a correction of an electrode voltage characteristic.

Abstract: The present disclosure relates to a method for operating a magnetic-inductive flow meter for measuring the flow velocity or the volumetric flow rate of a medium in a measuring tube and to such a flow meter, wherein the medium is subjected to magnetic fields of different polarity and field strength, wherein the changing between magnetic fields causes a voltage pulse in the medium, wherein an analysis of the voltage pulse is used for calculating a correction of an electrode voltage profile.

Abstract: The present disclosure relates to a method for measuring flow velocity or volume flow of a medium by means of a magneto inductive flow measuring device and to an arrangement having a magneto inductive flow measuring device, as well as to a filling plant with an arrangement, wherein the medium has a low conductivity. A high accuracy of measurement is achieved by provision of a first narrowing of a medium-containing pipeline and/or a second narrowing of a medium-containing measuring tube, wherein the pipeline leads the medium to a measuring tube of the flow measuring device.
