Zusammenfassung:A system and a related method is provided for correcting measurement glitches detected by a magnetic flowmeter assembly in determining a fluid flow velocity. The magnetic flowmeter assembly includes apair of electrodes that receive an instantaneous first and second electrode potential (voltage potential), Ue1 and Ue2, so as to determine an instantaneous induced voltage Ue across the fluid. A signal processor sends a digital signal of the induced voltage (voltage signal Ue) to a micro-processor, which processes the signal data and computes the corresponding instantaneous fluid velocity, v. Moreover, an instantaneous glitch detection variable Um is computed based on the electrode potentials (Ue1 and Ue2), so as to detect the presence of measurement glitches in said electrode potentials, wherein the signal processor will provide a digital signal of Um to the micro-processor. As such, the flowmeter assembly is able to correct for the measurement glitches by manipulating the instantaneousvoltage signal Ue, such th
