发明名称 METHOD FOR DETERMINING THE MEASURING PERIOD OF A MAGNETO-INDUCTIVE FLOWMETER
摘要 A method for determining the working point of a magneto-inductive flow measuring device for detecting volume- or mass-flow of a medium flowing through a pipeline or measuring tube, wherein an alternating magnetic field produced by a coil arrangement is caused to pass through the pipeline or measuring tube, wherein a sensor-specific rise time (tr) from reversal of the magnetic field up to reaching of an at least approximately constant magnetic field, as dependent on the particular magneto-inductive flow measuring device, is ascertained and stored, wherein a minimum measuring time (tM) for providing a measured value of flow at the at least approximately constant magnetic field is determined, and wherein an optimized measuring period (Topt) is determined as the sum of the sensor-specific rise time (tr) and the minimum measuring time (tM) and made available for operation of the flow measuring device.
