Operating method for inductive flow measuring device with suppression or elimination of interference components of AC voltage supplied to magnetic system

摘要

The operating method has interference components of the AC voltage supplied to the magnetic system of the inductive flow measuring device suppressed or eliminated, using a flux coil positioned directly in the effective range of the magnetic system, with evaluation of the induced voltage (Uflux) across the flux coil for determining the phase position of the interference voltage, allowing corresponding correction of the measuirng signal. An Independent claim for an inductive flow measurng device is also included.
